Hitachi Delivers Performance Without Sacrifice in New 7,200 RPM Travelstar Hard Drive

New 320GB Notebook Hard Drive Combines High Capacity and Superior Performance With Power Efficiency and Low Acoustics

SAN JOSE, Calif.—(BUSINESS WIRE)—Continuing its longstanding tradition of delivering superior performance with no sacrifices required, Hitachi Global Storage Technologies (Hitachi GST) today began shipment of its fourth-generation 7,200 RPM mobile hard drive, the Travelstar™ 7K320. The new drive delivers 60 percent higher capacity than its predecessor, while improving application performance by 12 percent and power consumption by 22 percent. The drive's quiet acoustics improve the experience of watching movies or listening to music on a notebook PC. The 2.5-inch drive is offered with optional Bulk Data Encryption for users wanting increased data security. Hitachi also plans to ship enhanced-availability (EA) models, designed to provide high-capacity storage for low-duty-cycle, 24x7 applications.

The performance attributes of the Travelstar 7K320 allow consumers to opt for a full-featured notebook or compact desktop model, while still achieving all the capacity and performance typically associated with a more traditional desktop PC. The new drives bring forth a number of essential features that are in strong demand from manufacturers of notebooks, compact desktops, gaming systems, blade servers and video surveillance systems. Some of these attributes include best-in-class operating shock protection of 400Gs, 5,400 RPM-equivalent power consumption and quiet acoustics.

"As operating systems have grown more complex, users have struggled with an overall decrease in system performance," said Larry Swezey, director, Consumer and Commercial HDD, Hitachi Global Storage Technologies. "Solid state drives (SSD) have yet to deliver an overall increase in speed, and certainly not at an affordable price. The 7,200 RPM speed of the Travelstar 7K320 provides an improved overall experience, at the capacities users want and at a far lower cost than SSD."

Gartner is predicting worldwide mobile PC shipments will surpass global desk-based PC shipments in the second half of 20091. This evolution has been driven by the ever improving performance-for-price of mobile PCs, relative to desktop PCs. Hitachi believes the greater availability of 7,200 RPM hard drives will help accelerate this trend, as more users realize the benefits of combining desktop-class performance with the convenience and portability of a notebook.

Advanced Features

The Travelstar 7K320 includes many features that translate into very tangible benefits for users, including:

* 320GB capacity for storing approximately 80 hours of high definition video, 320 hours of standard video, 100 movies, 80,000 4-minute MP3s or 160 games2
* The 7,200 RPM provides any operating system with a noticeable advantage in boot times and application performance. A SATA 3Gb/s interface and fast media transfer rates provide faster file copying and document retrieval, better graphics and improved game performance
* Best-in-class operating shock protection of 400Gs to minimize the effects of rough handling and vibration
* Power utilization on par with Hitachi's 5,400 RPM mobile drives, so that users can enjoy more "unplugged" notebook computing time
* The drive's quiet acoustics provide a richer audio listening experience for music, movies and games

Protect Your Data

The Travelstar 7K320 features optional Bulk Data Encryption (BDE), a capability that Hitachi has offered in its mobile hard drives since the start of 2007. Previously, data on a hard drive could be protected either through software-based encryption or a system-level password. Hard drive level encryption provides improved performance and a higher level of security than any of the previously available methods.

When employing bulk data encryption, data is scrambled using a key as it is being written to the disk and then descrambled with the key as it is retrieved. Thus, data encryption at the hard-drive level represents a more sophisticated approach of securing users' data and is generally considered to be virtually impenetrable. Another benefit is that it speeds and simplifies the drive re-deployment process. By deleting the encryption key, the data on the drive is rendered unreadable, thereby eliminating the need for time-consuming data-overwrite.

BDE models ship exclusively with a SATA 1.5Gb/s interface.

I said "void the warranty" and I meant it. The process I went through today means it'll be harder for me to complain to Apple if things get weird, so be cautious! Given the experience I've had, I think it will get easier and easier to swap HDDs, like RAM, because on the software side, at least as far as Apple goes, installing a fresh 2.5" SATA turns out to be straightforward, and ready for novices.

The key here is that there's no preparation needed for the new drive. As long as you've backed up your old drive to an external disk using Time Machine, you can prepare for the grand opening. I won't bore you with gory details, except to say that I found a good bit of guidance from this dude's blog.
The Process
From here on in, this issue may just as well apply to MacBooks and even iMacs as well as MacBook Pros, so everyone should take note.

Once you open up the system and swap out the drives, you can set the old drive aside, hopefully never to use it again. Assuming all went well, you restart the system and insert an OS X Leopard installation DVD. You won't need the OS installer on it, but you will need it to act as mediator between the Time Machine backup drive and the newly installed blank drive. Once it boots up (you may need to manually restart to get it to work right) follow these instructions CAREFULLY:

1. Choose your language.

2. At the main screen, choose Disk Utility from the Utilities pull-down menu.

3. Select the drive itself and click on Partition.

4. In the Partition menu, select 1 Partition and Options... where you choose GUID Partition Table. Click OK then Apply, then say "yes" to whatever warning comes up.

5. Once you have reformatted the drive, close the Disk Utility window.

6. Do Not Go Forward. Instead, when you see the main Welcome screen, click the Back button, which takes you to the language select page. It sounds silly but DO IT. This shakes the system into action.

7. Once you have reselected your language and are back on the Welcome screen, click Utilities and select Restore System From Backup...

8. The process should go smoothly from that point on. You simply select appropriate disks to copy your chosen backup data from your Time Machine drive to the new internal drive, as shown in the following sequence:

The Back Story
Originally I tried my swap without first clicking back to the language page, and the installer could not find my new hard drive. Disk Utility saw it and happily formatted it with the GUID partition, but even on the second pass, the installer wouldn't show it as a target option. All I got was this hollow emptiness:
I spoke with Jeerun Chan at Western Digital and asked him to try the same process, which yielded the same results. Then I tried it with another virginal hard drive, this time a 160GB SATA from Seagate. Between the two of us, we ran this test on three different configurations, with the same negative results.

The obvious but depressing solution was to just run the Leopard system installer, then use the migration tool to back up from my Time Machine drive. It's fairly smooth, and smart if you want a clean install on your new drive, but it's boring: it takes a few steps, and they're all obvious. I wanted a bit-for-bit dump from backup to new drive, fully automatic.

As I was installing Leopard on my second drive, the phone rang: it was Jeerun with the crazy back-button technique. I don't know how he thought to do it—I don't even think he knows, but the fact remains: when you have formatted your destination drive and are on the Welcome screen, click the back button and the process will work. If you don't click it, well, in our experience, it seems you will fail in your objective.

Obviously, this won't work if you don't regularly do a full system backup in Time Machine. If the omitted folders in your Time Machine options include system files, you won't be able to do this.

In truth, it might make sense to backup only personal files, especially since this process requires a Leopard install disk even to write the whole image back onto the new drive. Chen swears by SuperDuper, which is perhaps a better pro technique, one that doesn't require a system-install DVD. Still, I wanted to see if this major boast of Time Machine was all that it was cracked up to be. It is, and the end result will be tasty, as long as you don't forget that one little catch.

As with my last Time Machine HDD discovery, this one involves a little hocus pocus. While this method works, you may have your own trick, or a more scientific approach. If so, please share it in the comments below, and spare any fellow Mac users a frustrating afternoon.

Thanks to Jeerun and Heather at WD!
