Terabyte Hard Drive Put To the Test 376

Posted by Zonk from the where-did-the-missing-69-gigs-go dept.
EconolineCrush writes "As a technical milestone, Hitachi's Deskstar 7K1000 hard drive is undeniably impressive. The drive is the first to pack a trillion bytes into a standard 3.5" form factor, and while some may argue the merits of tebi versus tera, that's still an astounding accomplishment. Hitachi also outfitted the drive with 32MB of cache—double what you get with standard desktop drives—making this latest Deskstar a leader in both cache size and total capacity. That looks like a great formula for success on paper, but how does it pan out in the real world? The Tech Report has tested the 7K1000's performance, noise levels, and power consumption against 18 other drives to find out, with surprising results."

      RAID 1+0 is the way to go for redundancy. Unless you're unlucky enough to lose both drives in one of the pairs making up the array, you can survive more than one drive failing.

      It's also the way to go for speed - your controller doesn't have to calculate the parity bits for every write operation (yes I know the parity sum is simple - that doesn't stop it from adding a bottleneck).

      RAID5 is most useful where:

      1. You desperately need the space.
      AND
      2. You can't afford the drives (or, for that matter, power/larger RAID controller) required to acheive the same space in RAID 1+0.

          Likewise, many hardware controllers won't let you extend a RAID-5 array, (unless they implement some dynamic stripe size hack, a la ZFS's RAID-Z [sun.com]).

          Recovering from a failed 1+0 is ok if it is a "simple" failure.
          Please explain what a !simple failure would be. Here, let me give you a 'simple' failure case where RAID-5 would be pretty difficult to recover from: a drive fails in your RAID-5 array, and you lose power or experience another hardware failure shortly afterwards, before you can replace the drive. Whoops, you just became another victim of the RAID-5 write-hole [wikipedia.org] (see the section under RAID-5 performance).

          OK, here's why we use RAID-10 at my installation: it provides great performance and can survive multiple drive failures without the overhead of something like RAID-6. RAID-10 also has no 'write-hole'. Don't just take my word for it, though, check out this article [adaptec.com] from Adaptec comparing the merits of all the basic RAID levels and their nested brethren.

        The "bottleneck" of parity calculations is so small as to be irrelevant. Parity-based RAID levels are bottlenecked by the much higher number of physical disk operations, not the parity calculations.

        What are people doing with drives to make them fail?

        I've got the same question, as I've gone through a lot of hard drives over the years but only due to upgrading, not failure. The only exception was the IBM Deskstar GXP75 that had the whole click of death thing going on. I don't count that one since it was a known issue that resulted in a class action suit, which I didn't bother to take part in. The first one failed within a month, so I replaced it at the store, and the replacement failed after a day. Replaced again. The third one failed after a week but I was tired of going back to the store by then so tried an experiment - the click of death was kicking in somewhere near 500MB after the beginning of the drive so I repartitioned it to leave the first 500MB unpartitioned. My experience with the drive up to that point told me that wherever the click of death manifested, it would consistantly happen in whatever part of the drive it first happened at. That drive has been in constant use ever since then (it's been like 5 years or so by now hasn't it?) and still works great, since it never accesses the 'bad part' anymore.

      For a decimal megabyte versus a binary one, there's 48 1/2 KB difference.

      For a gigabyte, there's about 70 megabytes difference.

      When the marketing department figured out they could make their drives look 5-10% bigger than what they actually were to all non-techies they took advantage of it.
      • It's worse than that actually, because as the sizes grow, the disparity grows too.
        • When you say 1KB, the difference is 2.4% or 24 bytes.
        • When you say 1MB, the difference is 4.8% or 48KB.
        • When you say 1GB, the difference is 7.4% or 74MB.
        • When you say 1TB, the difference is 10% or 100GB.
        So, the higher the capacity, the more difference is there between binary and decimal units. 2.4% difference is significant enough, but it's not as bad as 10%. Lacking 100GB, or a full tenth of the capacity is however quite noticeable.

When talking about m/g/k bits the convention is to use powers of 10, and when talking about bytes it is to use powers of 2.

      In the days of the Apple II people and marketing used power of 2 for both ram and storage, as it's quite impractical to do otherwise when you worked so close to the metal (apple commodore and spectrum users often knew the address of ram and rom blocks for their machine).

      Then some clever biz heads started using power of 10, but it was several years later.

      Unfortunately, using the kilo- mega- etc. prefixes is accurate for base 10.

      Depends on your use... I work with a lot of images and my drive has a 16Mb cache. When I save an image that's <16Mb, it's almost instant and I can start work on the next one. If the image is >16Mb, it takes a good 5~15 seconds for the drive to thrash around until it's saved it. For me, yeas, a large cache makes a difference as most of my images are in the 10~50Mb range.

        That's probably because write-back caching is enabled on your HDD but disabled in your OS (that's the default with Linux). Turning on write-back caching on your OS which will probably will make much more difference than a larger HDD cache.

        However, write-back caching is dangerous, since in case of a power failure, it may seriously damage your filesystem.

    I'm not that convinced by the testing methods here. The boot and load times page shows 20 seconds difference between the slowest and fastest drives which they barely comment on, and yet the drive with the slowest boot time is among the quickest when loading Far Cry and Doom 3? Something is not right there.

    And if they're really timing level loads with a stopwatch, why on earth are they quoting 2 decimal places (and besides, the variability in reaction time is accounting for most of the supposed differences in any case). Half of their tests don't appear to tell anybody anything significant, and the most worthwhile page in there is the conclusion. Pretty graphics though.

    Interestingly, this form factor would neatly fit some 512 MicroSD cards leaving enough room for mechanics (slots, frame) and electronics. Take 512 2GB cards, you get 1 terabyte of solid state memory. Each of the cards can work independently from the others = easy RAID of 512 disks = quite insane speeds possible, and cheap replacement of failing parts (you replace a single failing card, not the whole device). Of course the price would be higher, but still the 1TB drive isn't cheap for sure, and without RAID.

    The drive is the first to pack a trillion bytes into a standard 3.5" form factor

    Hard drives used to be physically much bigger [wikipedia.org], when the interface tech was "MFM: 5.25" diameter, and "Full Height" was about 3.5".

    Physically smaller discs have faster access times and lower power consumption. But why not use larger discs for their higher data capacity, without wrapping each smaller chunk in the same electronics overhead for rotation and data transfer? And get the faster data transfer at the outer cylinders from their faster angular velocity?

    At a guess, I'd say that a 5.25" full height HD could have 2.5x the 3.5" capacity per platter, and probably at least 5x the platters, for about 12x the capacity. The access times across the large areas would be larger, but for large files that wouldn't matter as much (as long as they're kept defragmented).

    These truly "large" drives could be the best for archiving, thrown back in place after an emergency and gradually replaced with 3.5" disks (if necessary) as they continue to run.

    We could have 12TB drives with the same encoding tech as these Hitachis. And they'd cost less per TB than the 3.5" ones, because they'd have more storage per overhead hardware. Where can I get one?

      Except they'd have more parts, more complexity, and the larger components would need to be made to even finer tolerences since they need to remain well aligned over a much larger area (and they'd need to be stronger if you wanted to keep the same sort of RPM). They'd be much more expensive, and you'd probably still have to drop the density per platter a lot to keep it within the realm of sanity, not least because of things like thermal expansion having a much larger effect.

      File next to the disk with multiple drive head assemblies; possible, but just not worth it when you could just fit more, smaller, cheaper, independent disks in the same space.
