    In reply to Building a NAS? Skip the Performance Drives
    i'm running (6) 7200rpm drives in my FreeNAS box. i guess i could have gone with 5400rpm, but i already had all the hardware so i didn't really buy new components when i put the unit together.

    @waclark57 i think you missed the point. the post clearly says, "The main bottleneck in any NAS is the RAID engine. Since many NAS units don't include a dedicated controller, oftentimes the speed of the drive just doesn't matter. If you're using a blazing-fast hardware RAID card in your own custom built setup, then drive speed might make a difference. But for most consumer units, the controller is the bottleneck."

    with that in mind, drive speed obviously isn't an issue in consumer based NAS systems. sure if you have maddd money to spend on high end hardware, and you have a beefy raid controller, 10k or 15k drives will make a difference. #diy

    I'm using Western Digital Green drives in my unRAID setup. [www.lime-technology.com]

    Currently at 2TB + parity and expandable up to 6 drives before I have to upgrade the software license to the next tier (16 drives). #diy

    In reply to Building a NAS? Skip the Performance Drives
    I read this article yesterday and there are a few points that need to be noted. First they used older 7200 RPM drives and current generation 5400 RPM drives. It would have been more meaningful if both sets of drives were current generation.

    The other note is that if you are setting up RAID 1 the 7200 RPM drives may actually be faster. This is because in the article they rationalize that it is the lack of a hardware RAID controller that causes the bottle neck because the CPU is doing all the XOR calculations. However in RAID 1 no XOR's are calculated because the drives contents are identical.

    just my 2 cents #diy

    That's why you get one of these:
    [www.promise.com]

    Put half in RAID 0 and half as backup....(I forget which RAID number that makes it) and hook it up via Fibre channel to your Xserve that you're logged into via open directory (and that your home folder is hosted on) via gigabit ethernet.

    What would LHer's recommend in terms of the best reliability 1TB drives for a NAS? Is that size in the sweet spot at this point? Am I going to significantly decrease reliability using 2TB drives? #diy

    @AmphetamineCrown: The Western Digital Caviar Black drives are by far the most reliable. [www.newegg.com]
    In fact, I just ordered two of these yesterday!
    Judging from current trends, virtually all of the 2TB drives currently out have pretty bad reliability track records. I had considered them, too, but I don't want to waste money on them.

    @AmphetamineCrown: If you're primary goal is the reliability of an individual drive and you're willing to pay the premium an "enterprise" drive like the Barracuda ES.2 or something from the newer Constellation line is going to give you the best reliability, especially if you plan on running 24/7.

    If cost is more of a factor, you might consider 1.5TB drives. Seagate (Barracuda LP), WD (Caviar Green), and Samsung (Eco Green F2) all have low-spindle-speed 1.5TB drives. Put them in a RAID 5 or RAID 6 configuration for reliability, utilize the 3-year warranty if needed, and you'll be fine.

    I personally just put together a NAS with 6 1.5 TB Barracuda LPs in a RAID 6 running the Openfiler NAS software and its been running like a champ. 70MB/s over gigabit ethernet without jumbo frames enabled. #diy

    @brisketboy: @David Frederick Becker: I've actually been using the Barracuda ES.2s in my 6 drive ReadyNAS. It is about a year old, and I replaced one a couple months ago when the monitoring software started detecting errors. Now I'm starting to see errors on two other drives. As easy as they are to replace, I'm not really liking the concept of running through 3 drives a year.

    Maybe I'll try the Caviar black drives and see how they do. Seems like I'm going to develop quite the history with replacing drives. #diy

    USB only is a dealbraker. Hear that LaCie?

    Unless it's USB 3.0 which is supposed to be 1000000% faster than anything USB out there.

    @AldenOedipus: Is anyone using USB 3.0 yet? Anyway, I think that they just used USB to keep the cost down. FW peripherals are generally expensive. Western Digital gets away with their prices by putting the shittiest hard drives they can.

    I kinda like it. But USB 2 only is kind of disapointing.


    Also i don't like the fact that these devices always seem to be surrounded by monkeys throwing stuff at each other and also the devices makes planets explode... I like my Jupiter, europa be damned!

    @circa86: I bought four of those Porsche design 250GB drives... All of 'em failed about about 4 months. I think the Porsche design, while visually interesting, sucked vis-a-vis heat dissipation.

    @Thud: I feel very lucky, albeit wary, about my Porsche LaCie FW drive. It's been 2 years now and it hasn't failed me yet, but I have another drive as a backup so I won't lose anything if it dies. :S

    USB 2.0 only? Wow. I would have expected a lot more out of a 2TB drive just hitting the market. At least throw in Firewire 800 if nothing else...


    If you really want a performance 2TB external, go with the setup I just picked out: [jevidon.tumblr.com]

    @Justin Evidon: If it were Firewire, the price would've been a great deal more than this, though LaCie generally has some of the cheapest Firewire external drives out there, with Western Digital coming in a bit cheaper. I wish it were network capable. Gigabit Ethernet can be a great deal faster.
