The Hitachi Deskstar 7K2000, is a 3.5-inch drive that fits inside any compatible computer or enclosure. As expected, the drive uses the SATA interface and is Energy Star-rated. Hitachi didn't reveal pricing, but said they were shipping the drive immediately. So be on the lookout. [Dvice]

Hitachi's proprietary biometric authentication system requires that users first register an account (probably linking their vein pattern to a credit card), but it allows one to purchase, say, a delicious can of green tea or icy cold black coffee by inserting a cautious hand into a machine for a quick scan.

Of course, the system exploits your identity a bit in the process, using age and gender information on file to display an appropriate video ad while you enjoy your refreshment. But hey, if a public Coke machine light-probing your innards doesn't bother you, why should a quick sales pitch? [MSN News via CrunchGear and Getty Images]

It's the first drill of its kind to feature a counterweight strong enough to cancel out what is undoubtedly some pretty serious recoil. I still think it would take all the counterweight in the world for this not to shake my spaghetti arms out of their sockets in two, maybe three seconds. But that picture—can't take my eyes off it.

The phone's 3.1-inch display is the first of its kind to have 3D-capabilities and can be swiveled horizontally to be more TV-like. There's not a lot of content being offered to accompany the phone right now, which is just as well since Hitachi doesn't recommend that people use the 3D feature for too long. Kids under the age of 6 shouldn't use it at all.

Besides the crazy stereoscopic screen, the Wooo also comes with a 5MP camera and a “Global Passport” that will connect you to KDDI au's network from anywhere in the world except Thailand, Guam and Canada. It'll be available in three colors by April—in Japan only, of course. [KDDI au]

Some say that the end of the trusty hard drive is near, killed by SSD. But let's not be so quick to give up on a technology that stores a whole terabyte for $100.

It'll be years before solid-state flash-memory disks (in this case usually referred to as SSDs) let us cheaply bank the same amounts of data as trusty old hard disk drives for a reasonable price. So, you might as well know how they work, 'cause honestly, they'll have a place on or next to your desk holding all the crap that won't fit on daintier solid state drives—HD movies, huge pictures, music and who knows what else if you're Jason Chen.

What Goes on Inside
The reason hard drive is abbreviated as HDD is that it's really a hard disk drive. Inside you've got what's called a "platter," which is a magnetized recording surface that spins around really really fast, with a head that zooms across the disk to read and write data, think kinda like a record player, except that the head never actually touches the disk except, as you will see below, when bad things happen. [Image via Wikipedia]

Hard drives also come in a few different sizes, with 1.8", 2.5" and 3.5" being the most common, but they've been bigger (and smaller). 3.5" is for desktops, 2.5" is for notebooks (or obsessively quiet desktops), and 1.8" is what goes in classic iPods, MacBook Airs and other small portable devices.

The more platters a drive has, the more data it can hold, but most advances in storage have focused on increasing storage density. A really high-capacity drive can have four platters, while many 3.5" desktop models and some elite laptop 2.5" drives have three platters. Most laptop drives and all the 1.8" portable-device drives that we know of are limited to two platters.

The real catalyst for those 1TB and 1.5TB monster drives pooped out by Hitachi and Seagate wasn't platter stacking, though. It was perpendicular magnetic recording, which allows for triple storage density by storing data vertically (or perpendicularly) along the platter's recording layer, rather than spreading it out across it horizontally (parallel-ly?). However, data is more fragile and susceptible to erasure when stored vertically, hence the slow creep in precision allowing for greater storage densities and capacities.

What All Those Numbers and Letters Mean
You might've noticed hard drives are often labeled as IDE or SATA or PATA or PITA (kidding), with specs like 5400RPM or 7200RPM, plus they come in various sizes, like 1.8, 2.5 or 3.5-inches. Confusing, no? So here's all that crap means.

RPM means the same thing it does in cars, rotations revolutions per minute. In hard drives it's important because the faster the disk spins, the faster it can read and write data. 7200RPM is the standard for desktop drives, but performance models run at 10,000RPM or 15,000RPM. Notebook drives typically run at 5400RPM, because they're smaller, but recently, you can order them with 7200RPM to get more performance at the cost of battery life.

A higher RPM is the single greatest performance variable, since the faster it spins, the more data it can read or write within whatever time frame—it also makes access faster, since the head doesn't have to wait as long to pass over the right data once it's moved to the right spot. And a faster (lower) seek time, basically, refers to how long it takes for the drive to move its head where it needs to go to read or write data. High end drives have a seek time of just 2ms, while typical consumer drives are close to 9ms. Also, the higher the buffer—most typically 8, 16 or 32MB—the more data it can pre-cache, though Tom's Hardware found that you getdiminishing returns there.

How They Connect
The various kinds of drives essentially refers to how it interfaces or connects with your computer's motherboard. There are a bunch, but only a few worth knowing. Up until the last few years, the dominant standard was ATA, or Advanced Technology Attachment. Once SATA, or serial ATA, came onto the map (more on that in a sec), regular ATA picked up the alternative name parallel ATA.

Further revisions to the ATA spec allowed for hard drives with greater storage and faster transfer speeds, and you might see drives using the later spec revisions called "Ultra ATA" or something similar, and they can transfer data at 133MBps (which is slooooow). ATA drives are commonly called IDE (integrated drive electronics), but ATA is more precise. If you've ever messed around inside a computer, you'd recognize them because they connected to fatass ribbon cables that take up a lot of room. The third major interface, which you should know of, but not necessarily about, is SCSI (pronounced "scuzzy"), which was primarily used in the enterprise or high-end space when ATA was still king. The ATA/IDE interface also confused some with its master/slave assignations, which, as you'll see, is no longer a problem.

Okay, so the current hard drive standard in consumer PCs as of a few years ago is SATA, which is worlds better than ATA. For one, it's faster—first-gen devices ran at 1.5Gbps, but now they're up to 3Gbps, and are on the road to hitting 6Gbps. Also, their cables are way thinner, for better air flow and less tangly crap inside your case. And because they're smarter and don't depend on a lot of configuration, they're easy to work with, and are even hot-swappable. Newer external drives use a variant of SATA, eSATA (e for external) that essentially just moves the port to the outside of the computer case, delivering SATA speed for peripherals. Soon, eSATA will come in a bus-powered format, much like the smaller portable USB drives you see today.

Fast seek times are different than fast transfer times from a good interface—one pertains to how quickly the data can be located on the disk, and the other is how fast it can be sent over. To describe it in somewhat oversimplified terms, you can see how a slow interface on a fast seek drive would be better for a system that's constantly shifting tiny bits of data, where a fast interface on a relatively slower drive is good for moving really large files around.

Why They Die
Remember how I said the head usually never touches the drive's platter surface? When the head actually does touch the drive platter, it's what's called a head crash (check out the video above), and it means you're skee-rewed. Normally the head flies on a tiny pocket of air, but a single particle can make the head bounce on the disk, totally hosing the magnetic layer, especially at higher RPMs. And it just gets worse from there, because stuff scraped away by a head crash making it more likely that more head crashes will happen. More mundanely, the delicate mechanical parts eventually just wear out over time, which is typically measured by the the drive's rated mean time between failures. Unfortunately, there's not a whole lot you can do to predict when your drive is gonna go down in flames, unless you bought a drive from a series suffering manufacturing defects.

So what is really the single most important thing you should know about hard drives? Back your crap up, they may be awesome, but that doesn't mean they're without weakness.

It's not every day that you get to check out the world's thinnest LCD HDTV, let alone all three "ultrathins" currently in production, but that's what's going down. Sharp's super insane new flagship, the Limited Edition Aquos LC-65XS1U-S, arrived at my door in a bulletproof shipping container, 138 pounds of metal and glass measuring 65 inches diagonal that you can barely see from the side. Yes, in spite of its full-frontal gravitas, it measures only an inch thick at its edge, and a slightly more flexed 2 inches in the middle. It's gorgeous and ridiculous and designed to hang on a wall with no more protrusion than a dainty sketch in a frame—only it can blast Casino Royale at 1080p, 24 frames per second, while your face melts, and I'd have to sell my car twice over to buy it.

I love you Giz readers too much to stop with something that none of us can actually afford—and if you can afford it, you'll be decent enough to not let us know—so I called in the new slender 1080p models from Hitachi and JVC, too. As much lower-priced sets, I thought they'd just be the icing on Sharp's Limited Edition cake, but they turned out to be, in their own right, fine specimens. Let's review, shall we?

Who Thin?
"Ultrathin" is best defined, at this moment, as a TV that is mostly thinner than 2 inches.

Hitachi's Director's Series 1.5 UltraThin UT37X902 (37 inches listing for $1,900) got its name because it's an inch and a half thick across its entire panel. It is a monitor with speakers, but no tuner and the barest of inputs—one HDMI and one VGA—to help it keep trim. JVC's LT-46SL89 (46 inches for $2,400) on the other hand is a true TV, with digital HD tuner, 3 HDMI ports, 2 analog inputs with option of component, composite or S-Video, and a PC VGA input. That adds a bit to the girth—while most of its main panel is one-and-three-quarter-inches thick, there's a middle section that is a fat three inches.

To give you a sense of comparison, Pioneer's fairly slim and lightweight first-gen Kuro plasma is nearly 4 inches thick, with a slimming bezel that measures about half that. Pioneer isn't content there, though—its newest Kuro Elite monitors are quite trim, and you'll recall last CES the company showed off an unbelievably thin half-inch plasma screen that's presumably nowhere near production.

WTF Thin?
When I asked Sharp Aquos product manager Tony Favia what the fuss was about all of these new super thin TVs, he said that customers, particularly high-end ones, wanted a TV that could hang on a wall as flush as art, and even fill in for art as needed. That's why Sharp loaded the XS1 with paintings: When you push "Image" on the remote, up pop masterworks by Hokusai, Renoir, Seurat and Van Gogh, about 10 or 12 total. You can't leave the TV set on a particular image, though, despite the remote's discreetly stashed Play/Pause/Fwd/Rew transport buttons.

The XS1 achieves its thinness in part by farming out its functionality: An accompanying AV box, tethered by a single long HDMI cable, doesn't just handle all of the inputs, but the digital tuner and AquosNet internet access as well. It's so integrated into the TV's life that without it that, though I was able to run a video source directly, I couldn't even touch picture settings.

The thing about thin is that it's not cheap, and as such, manufacturers aren't at liberty to cut out performance to slim down the screen. This is probably why the biggest successes in TV sales—Sony, Panasonic, Samsung and LG—haven't expressed outright interest in marketing slim product. In fact, Sharp is smarter than JVC and Hitachi, aiming the thin concept at particularly spendy customers (Russian oil barons, professional golfers, Alaskan governors who may soon sign book and/or TV deals), rather than just going thin to differentiate itself at the Best Buy.

You Can't Afford It
The sleek all-metal Sharp 65-inch XS1 Limited Edition costs $16,000. The 52 incher costs $11,000. The build materials have a lot to do with the cost. A critically acclaimed, plastic-encased 3.7-inch thick Pioneer 50-inch plasma (that weighs 13 fewer pounds) lists for around $4,000, and sells for as little as $2,500. So you're not a sheikh, I'm not a sheikh, why are we talking about a sheikh's TV? Favia said the company went for a "no compromise" approach, and as hard as I looked, I found just one technical compromise, one most (sheikhs) could live with. If the damn thing didn't cost so much, the XS1 would be one of my favorite TVs ever.

Speaking of the Kuro, I placed a first-gen model side-by-side to calibrate and compare, and though the Sharp LCD wasn't always as perfect as the Pioneer plasma, I was surprised to see how well it kept up. Even though the LCD is equipped with 120Hz Fine Motion Enhanced blur reduction, I realized that during the action sequences in Casino Royale it went with native 24p (24-frames-per-second) movie playback. There wasn't any noticeable blur. In fact, thanks to the massive LCD's dazzlingly snappy 4-millisecond response time, I found that you really didn't need 120Hz at all.

Contrast Is King
In the all-important land of contrast, this Sharp scores big. Sharp has, in the past, been criticized for confusing contrast with an overuse of darkness. The XS1 is obviously a ground-up redesign, but in that arena in particular, I found I could tweak settings to walk the line between crushed and bleached blacks. You don't see charcoal gray when you're supposed to see pitch black, and yet dark textures are plainly visible.

This has much to do with the tight grid of RGB LEDs behind the main panel that light only what's needed. This technique has recently earned Sony and Samsung high praise for contrast and color reproduction, but it has a third crazy attribute: The 65-inch Sharp is capable of using less energy than the 46-inch JVC and even the 37-inch Hitachi, because it lights only what it needs and doesn't require the constant glare of a fluorescent light source.

When it comes to specific wattage demands, the Sharp hovered in the low to mid 100s with peaks upwards of 200W. The plasma was averaging 250 or higher, maxing out during the brightest scenes at 400W. The JVC's 46 incher could be set, using the backlight slider, anywhere from 98W to 200W, and the Hitachi similarly ranged from 83W to 171W. Though nice and slim, both of these sets use constantly lit fluorescent lamps.

While contrast on these smaller TVs didn't immediately seem as good, I got a sneaking suspicion that LED backlighting is, at least in part, a psychological trick. See, constant FL light means that, when watching 2.35:1 widescreen movies, you get a touch of gray in the bars at top and bottom, at least you do unless you dial down the backlight and sacrifice some whiteness. With LED backlighting, the LEDs behind the letterbox's black bars are simply turned off. You perceive that contrast to be better since there are fewer dead giveaways of less-than-perfect contrast.

I'm not trying to uncover a mystery here; I'm just saying that once I ignored the light shining through the black bars, I was happy enough with the contrast and color—demonstrated below by Disney's new Sleeping Beauty Blu-ray, our friend HD Guru Gary Merson's favorite color-gamut test source along with, naturally, Southland Tales—on both the JVC and Hitachi. Sometimes "good enough" is actually "good."

The Last LCD Issue
The funny thing is that two of the three test TVs suffered from an annoying LCD-related problem, and it wasn't the cheaper two. Both the Sharp and the JVC, which in many ways could not be more different as TVs, lost color saturation and even shifted in tint when viewed from the most peripheral angles.

Viewing angle issues are far from new: Projection TVs and LCDs have continued to suffer from them for years and years (in some cases decades). And maybe you think that it's no big deal, since most people watch a TV sitting head on. But I think that ultrathin TVs—intended to hang flush on walls, and without a pivoting mount—should be especially good looking at every angle where the picture is remotely visible. The Hitachi alone managed to hold its colors to the very edge, losing only brightness, as you'd expect.

New Hope
In the end, I think this review session did more to renew my faith in LCD technology than it did to sell me on the whole ultrathin thing. I spent years at line shows wondering why anyone would buy an LCD when plasma was an alternative, and even the amazing rise of Sony and Samsung in the LCD space was clouded by the simultaneous rise of all those extra-crappy savings-club TVs.

It's worth noticing that these ultrathin sets don't hail from the current Korean, Japanese or Chinese TV powerhouses. But as flagships from their companies, they do an even better job boding well for the whole industry, at least from a technical perspective. Plasma can still enjoy its high noon, but at a cost—nothing here looked better than the Kuro, but it took twice the energy to deliver that marginally better picture. And when it comes to hanging these bastards on the wall, well, let's see if Pioneer's still going to make good on that ultra-ultrathin promise from last CES. If not, these LCDs are going to be the slim-o-cizers to beat. That is, until the first 40-inch OLEDs hit the market. [Sharp Aquos Limited Edition XS1; Hitachi 1.5; JVC SuperSlim]

For live video, the camera runs its own IPTV server, which compresses the video down to H.264 in real time before sending it out to a compatible TV. The folks at Tech On are claiming this all goes down over 802.11g, though (and not n), so quality may not be the best. Cool capabilities to have built-in, though. And if anyone has a line on IDing the liquid-filled banana being filmed in that image, please share with the rest of us. [Tech On]

Hitachi Launches a Trial of GazoPa, a Similar Image Search Service

GazoPa Selected As TechCrunch50 Venture Project
SAN FRANCISCO —(Business Wire)— Sep. 10, 2008 Hitachi, Ltd. (NYSE:HIT)(TOKYO:6501)(hereafter "Hitachi"), announced today that it has launched a trial of a similar image search service called GazoPa as an invitation-only beta at TechCrunch50 conference in San Francisco. GazoPa was selected as a finalist at the conference.

GazoPa is a web image search service that uses features from an image to search for and identify similar images. In conventional image search, users do not find results of image searches to be as accurate as those of web page searches. This is often because some images do not have metadata, some have incorrect metadata, and some are difficult to describe with words. Therefore, keywords are not sufficient as the only conditions for image searches.

With GazoPa, users can overcome the limitations of metadata, and word descriptions. GazoPa enables users to search for similar images using characteristics such as a color or a shape extracted from the image itself. GazoPa even enables the use of users' own photos, drawings, and images found on the web, as search keys to locate similar images from the GazoPa database. Not only does GazoPa support photos but also searches video thumbnails. Unlike video sharing websites that use keywords to search, users can search for videos using images.

GazoPa enables searches at high speed even for large quantities of image data. GazoPa currently searches 50 million images crawled from the web within one second. Since GazoPa crawls the web continuously, it will soon be capable of searching more than 100 million images.

As the number of digital camera and camera phones increases steadily to exceed 1 billion worldwide, the number of digital images that are captured by digital devices also increases dramatically. It therefore becomes more and more important to search for a needed image from a large quantity of images in a short time. GazoPa overcomes the limits of keyword searches and introduces a new world to image searches.

Hitachi Debuts Three Format Hybrid Blu-ray Disc Camcorder

— Hitachi proudly presents the next generation HD camcorder able to record onto the next generation HD format, Blu-ray —

CHULA VISTA, Calif.—(BUSINESS WIRE)—Hitachi Home Electronics (America), Inc. continues to introduce state-of-the-art consumer electronics with its next-generation Blu-ray Disc Hybrid Camcorder with the ability to record onto the next generation HD format, Blu-ray.

A step above from its predecessor announced last year, the DZ-BD10HA from Hitachi’s Consumer Group contains several new features and improvements. A newly developed 7 mega pixel CMOS image sensor, which captures rich and vibrant videos and stills in FullHD (1920 x 1080) High Definition. The new DZ-BD10HA can also record up to 4 hours 20 minutes of 1920x1080 video or 8 hours 40 minutes of 1440x1080 video onto the built-in 30 GB HDD. Additionally, the built-in SDHC card slot provides added flexibility by allowing for Full HD video and still recordings.

The new DZ-BD10HA also offers a dubbing function that allows Full HD video to be transferred with the single push of a button from either the HDD or SDHC card to the BD drive, all within the camcorder, without having to connect to a PC. Editing functions such as split, splice, delete, merge, and transitions can also be performed within the camcorder before dubbing for additional functionality. The Transcoding feature allows for the camcorder to transfer full HD videos off the HDD or SDHC card to standard definition DVD discs for the sharing of videos with friends and family who may not own a Blu-ray player yet.

Another new feature added to this year’s camcorder is face detection, which automatically detects and focuses on faces to provide the most true to life color accuracy and clarity. Additionally, Hitachi has developed a compact, low power consumption, quiet and highly reliable 8cm BD/DVD drive, which results in a 20% reduction in overall volume compared with last year’s DZ-BD7HA Blu-ray hybrid camcorder.

“Hitachi is well known for having introduced the world’s first DVD camcorder, the world’s first Hybrid camcorder with a DVD drive and a Hard Disk Drive and the world’s first Blu-ray camcorder,” said Daniel Lee, Vice President of Marketing at Hitachi Home Electronics, America. “Hitachi continues to improve upon and deliver cutting-edge and innovative products, and is pleased to offer the latest upgrades in camcorder technology to its customers and consumers. The new DZ-BD10HA underscores Hitachi’s commitment to developing original technologies that consumers can easily embrace.”

While keeping the same core design as the previous Blu-ray camcorder, the DZ-BD10HA has several added features and an ameliorated design. These features include:

Three Format Hybrid Compatibility

This camcorder has the versatility of being able to record HD video onto three separate formats (Blu-ray Disc, Hard Drive, SDHC) and provides the flexibility and ease of playback and long recording time all in one camcorder.

7 Mega Pixel CMOS Image Sensor

The CMOS image sensor in this camcorder is designed to record the highest resolution video with effective 4.67 mega pixels while minimizing distortion and artifacts to ensure the most clear and vibrant high definition picture. The camcorder is also capable of capturing 6.22 mega pixel stills onto an optional SD or SDHC card.

One-Touch Dubbing

With the push of one button the user can transfer HD video from the SDHC card or hard drive to a Blu-ray disc all within the camcorder; this eliminates the need to turn on a computer.

Face Detection

This feature automatically detects and focuses on the face to provide true-to-life color accuracy and sharp picture quality to the user.

O.I.S. (Optical Image Stabilization)

O.I.S. automatically detects and cancels camera shake by accurately stabilizing the lens to produce the most sharp and vibrant picture possible.

Pricing and Availability

The Hitachi model DZ-BD10HA model Blu-ray Hybrid with built-in 30GB hard disk drive (HDD) is priced at a Manufacturers Advertised Price (MAP) of $999. The camcorder will be available in Japan on August 9th and will be available in North America in September 2008.

Hitachi Delivers High-Capacity, Low-Power Digital Video Storage For the Tera Era

Hitachi CoolSpin Technology Delivers Low Power and Quiet Acoustics for Digital Video Applications

SAN JOSE, Calif. – July 30, 2008 – Hitachi Global Storage Technologies (Hitachi) today introduced two new CinemaStar™ hard drives optimized for use in digital video recorders (DVRs) and set-top boxes. The CinemaStar™ 7K1000.B is available in a broad range of capacities up to one terabyte (1TB) and the CinemaStar 5K320 delivers up to 320GB of capacity and incorporates innovative Hitachi CoolSpin™ technology.

CoolSpin drives use a motor speed optimized for low power and acoustics, enabling Hitachi to deliver the industry’s quietest, most energy-efficient 3.5-inch hard drives. Hitachi CoolSpin enables a new generation of DVRs and set-top boxes that store more hours of video, run more quietly and use less power.

The new Hitachi CinemaStar drives include the following:

Drive mechanics designed for continuous 24x7 operation

Silent-seek acoustics for nearly inaudible operation

Three low-power idle modes for best-in-class power utilization and heat emission

Smart Command Transport (SCT) and SmoothStream technology optimizes the drive for uninterrupted audio and video streaming

Expanded temperature range to enable fan-free DVR designs

Ramp load/unload design to increase shock protection and power savings

Thermal monitoring and fly-height control to enhance drive reliability during lengthy video encoding/decoding sessions

Optional Bulk Data Encryption (BDE) for increased protection against data loss

Proven perpendicular magnetic recording (PMR) technology helps to ensure maximum stability, reliability and data integrity

CinemaStar 7K1000.B

The CinemaStar 7K1000.B is based on the recently-introduced, second-generation Hitachi 7,200 RPM terabyte hard drive family. The new 3.5-inch drives, available in capacities ranging from 160GB to 1TB, leverage seven generations of power management technology to deliver best-in-class low power and thermal emissions. Hitachi used HiVERT technology, first pioneered on 2.5-inch Travelstar drives, to increase the power efficiency characteristics of the drive. The CinemaStar 7K1000.B enables device manufacturers to develop DVRs that run cooler and require less power, which ultimately leads to longer product life.

All CinemaStar products are enhanced with silent-seek acoustics to deliver bedroom-quiet operation, and a Hitachi patented load/unload ramp mechanism that helps prevent disk wear and protects the disk during non-operation. The CinemaStar 7K1000.B is also built using the industry’s most reliable perpendicular magnetic recording (PMR) technology for maximum stability, reliability and data integrity.

1TB CinemaStar hard drives can hold up to 247 hours of MPEG-4 encoded high definition video1 and can support more than 10 simultaneous data streams.

CinemaStar 5K320

The CinemaStar 5K320 provides up to 320GB capacity and features innovative CoolSpin technology to deliver a new level of power efficiency and quiet operation for digital video applications. Key to CoolSpin technology is an optimization of motor speed to provide an ideal balance of performance, power utilization and acoustics.

Both CinemaStar drives announced today combine a targeted 1.2M hour Mean Time Between Failure (MTBF)3 and extended operating temperature range to maximize DVR lifespan. At 3.1W idle power, the CinemaStar 5K320 helps meet low power compliance targets for consumer electronics devices and allow consumers to save on their energy costs.

The digital video recorder market continues to experience robust growth. IDC estimates that shipments of hard drives for personal video recording applications will grow at a 14% annual growth rate between 2007-20122.

“Hitachi has been making dramatic improvements in power savings generation to generation and our CoolSpin product line in particular, sets new standards for power-efficient audio/visual hard drives,” said Larry Swezey, director, Consumer and Commercial HDD Marketing and Strategy, Hitachi Global Storage Technologies. “The Hitachi CinemaStar drives are designed to excel in DVR and set-top box applications, where cool operation, quiet acoustics and overall power efficiency are of critical importance.”

Availability

The CinemaStar 7K1000.B will begin shipping to customers worldwide in August and the CinemaStar 5K320 is expected to ship in September, 2008.

The optics remain largely unchanged, with a 10x zoom but this time coming with an optical anti-shake system. There's also face recognition for exposure and focus automation, and the same Picture Master image processing tech built in.

In HX mode, at full 1920 x 1080 pixel resolution, the cam manages a 15Mbps bitrate and fits about 4.5 hours of recording onto the 30GB drive, or an hour onto a 8-cm BD. At 720 x 480 resolution, in SX mode (9 Mbps) it'll fit 20 minutes onto a DVD. Its battery will shoot for about 80 minutes, and the whole package weighs about 1.27 pounds and measures 3.1 x 5.5 x 3.4 inches.

Available in Japan at first, from August 9th for around $1,400. [AVWatch]

The change in range is due to the chunk of spectrum being used (5GHz for WHDI and anywhere from 3.1 to 10.6 GHz for UWB). UWB is a low-power, short-range broadcast because it has to play nice with the other protocols found on the wide breadth of spectrum it calls home. (For better or worse, Monster's wireless HD kit is wireless up until the point it needs to use your home's coax wiring to gain whole-house coverage).

WHDI, however, is camped out in a chunk of unlicensed 5GHz spectrum just like 802.11n Wi-Fi, meaning it must be able to tolerate the reasonable levels of interference only from other devices that use the same frequencies, and can broadcast at higher power levels than UWB—enough for a range of "over 100 feet." WirelessHD, a third major spec also funded by Samsung and Sony, plus Panasonic, Toshiba, LG and NEC, uses the 60GHz band, and apparently has problems unless the transmitter and receiver are within line-of-sight.

Components will be paired through menu systems using a pass-key, like Bluetooth. The spectrum can hold around six streams of 1080p video at a time, although real-world interference may vary. A likely scenario would be streaming from a WHDI cable box or Blu-ray player downstairs to 3 TVs throughout your house while still having room for HD gaming in the den.

The fact that a few heavies like Panasonic are still notably missing could mean another standards battle is on the horizon. While WirelessHD already claims a published 1.0 spec, and Monster's UWB product should be out by the fall, the WHDI spec is due to be finalized at the end of the year, with products hopefully popping up in time for CES '09. Stay tuned until then—as one format war ends, another begins.

Update: By now, most of you have figured out that Iomega and LaCie only make the housings, so if the drive itself fails, you have to unscrew the box to see who the real culprit is. Also, anyone voting for IBM can just vote for Hitachi, which bought the whole IBM storage division a number of years ago.

I will say that, after reading the comments, I feel bad that I didn't divide Seagate and Maxtor, but then again, there is only one company to blame now—let's just hope they're not merging all of their manufacturing!!! My guess is that Maxtor may have ended up the biggest loser, at least proportionately, and Seagate, solo, would have looked a lot better than WD.

As for those of you who complain that this poll is not scientific, you are TOTALLY RIGHT!!! It's not scientific. Go back to your Science and your Nature for the raw research, cuz over here we're talking about life experiences.

Why We Care: MRAM uses just 10% of the power of DRAM and offers instant-on computer booting. Plus we're sick of typing "DRAM."

Why It's Too Good To Be True: Engineers still needs to get their MRAM failure rates down to 1% over a decade before the technology will be deemed acceptable. Everyone thinks that this can happen by 2015 (which is a lot further off than, say, tomorrow). [NikkeiNet via techradar]
