    "Operating System Stated Capacity"

    Lets be clear so maybe you can be clear in the next article.

    The IEC, IEEE, CPIM, and NIST define Giga (G) as 1,000,000,000 or one billion.

    The same standards organizations define Gibi (Gi) as 1,073,741,824.

    As such, by standard definitions, these hard drives are in fact 1000GB, or 1000 gigabytes.

    Your "Operating System Stated Capacity" really means "Windows Explorer Capacity". Other operating systems don't get it wrong like Windows does. So if you report this wrong information at all, you should make the truth known -- that Windows is well known to WRONGLY report GiB as GB (and MiB for MB and so on).

    Those drives have 1000 gigabytes of space. Windows Explorer and solid state memory companies report the space incorrectly.

    Looks like another review of the 7200.11 drive where it appears the reviewer didn't remove the jumper limiting it to SATA 1. Interface bandwidth burst rate is over 200MB/s on my 7200.11 with the jumper removed. Reply

    That's also the first thing that came to my mine... "dude forgot to remove the jumper." Reply

    Dave, is there a reason that Samsung's 1TB drive
    was not included in this review? The drive is
    difficult to obtain in the US but is available in
    other countries at this point in time. Tomshardware
    has already posted a review, and there is also
    discussion taking place on storagereview.com

    It's a matter of availability, not of lack of interest. We do like the latest Samsung offerings - they simply didn't have a drive shipped to us in the lab in time for the article.

    If they get us a 1TB drive for us to have a look at, then we'll gladly put it in a future article.

    Thanks for reading!

    In the meantime, Tom's hardware did the Samsung Spinpoint F1 review[1], which showed it has great non-server performance. In fact, it outruns WD Raptor WD150ADFD in some tests. Power consumption is between 'cuda 7200.11 and Caviar GP.

    You get a lower overall price per Gig by using two 500 gb drives. Reply
  • Googer - Monday, November 26, 2007 - link

    With a pair of 500GB hard drives, you do not get it in a single volume, power consumption increases, RAID 0 decreases reliability and increases error possibilities.

    The fact that it takes two drive bays is a sore thumb to those who build small form factor multi-media systems with only one drive bay that will also funtion as a Digtal Video Recorder.

    I should also add, this "GREEN" drive is ideal for a TiVO upgrade due to it's large size, quiet operation, low heat, and noise output.

    One thing I would have liked to see in the article is a RAID test. Specifically, I wonder whether or not the WD drive with its variable rotational speed will have problems in RAID configurations.

    In my experience with the WD drives, the answer to this question is yes. I have two of the WD Terabyte drives in a RAID MIRROR setup. The issue I noticed is that while copying data onto the mirror from multiple sources, some data becomes corrupt. I contacted WD support about the problem and am waiting to hear back from them. Perhaps it is true that these WD drives simply do not work well in a RAID setup.

    Has anyone else experienced problems with the WD drives in RAID?

    Dear Darshan,

    Thank you for contacting Western Digital Customer Service and Support.

    The WD10EACS is a desktop drive. WD desktop drives do not work properly when used in a RAID array. I recommend you exchange your WD10EACS drives for the RAID model, WD1000FYPS.

    I was hoping they'd introduce ACS (Actual Capacity Specification) with the 1TB drives so when I look in My Computer it would actually say 1 TB under Total Size instead of 930 GB. Uncool :rolleyes:

    SI has settled on TB for 1 trillion for a long time. If you want 2^40 bytes, you'll need TiB (tebibyte). While computers have been using Kilo, Mega, Giga, Tera for a long time, the fact is that those were originally designated as 1000, 1000000, 1 billion, 1 trillion, etc. before computers began using the abbreviations. Computer scientists were lazy (as usual - I can say that because I studied CS) and simply used Kilo for 1024 because it was "close enough".

    As far as I'm concerned, "ACS" has been in use for a long time; now we just need to get operating systems and users to understand the correct meaning of SI prefixes. :)

    What...no check on wattage usage on the drives? If its a "green" drive id like to know how much power its actually saving. Reply
  • nowayout99 - Monday, November 26, 2007 - link

    Ditto. I was expecting to see some sort of power draw comparison, afterall the one drive is marketed as being "green."

    Instead, we're asked to take their word for it.

    Why is it that almost every single article Anandtech puts out has a conclusion that contradicts their own test results?

    Seriously. If the two drives are so different and so suited for different purposes, why are you even comparing them? If it's just to say that the WD drive excells at being green and the Seagate drive sucks at performance, why even bother with an article?

    You cannot judge the drives solely on the merits of the competition while ignoring what the drive is good at.

    This right here: "the redeeming feature of the Seagate drive is only that it turns in better results than the Western Digital drive". That's a no-brainer, and anyone could have guessed that by looking at the manufacturer specs. More to the point: wasn't that the goal of the article--to find out which of the two performed better? So, why, in your conclusion, do you completely ignore the fact that the Seagate drive is clearly the better performer?

    You judge the Seagate drive for not being quiet, for running hot, for having bad performance, yet you completely ignore the fact that in your little "head-to-head" comparison, it is the victor in terms of performance. By that same token, you praise the Western Digital drive for being quient, for running cool, and you completely ignore the fact that it performed worse than any other drive tested.

    The bias on this site is palpable. So much for honest reviews.

    Do you actually make a HD purchase decision solely based on performance?

    I actually liked the conclusion. Sure, the WD is slower in almost everything. But if you look at the real life benchmarks it's only about 5% in all apps except WinRAR. Is this difference high enough to offset the savings in price and power consumption? I think this is the type of question that the consumer should be asking, and the conclusion does a good job at doing just that.

    Anyway, if you do not like the conclusion, you can easily look at the facts and benchmarks only and make your own call. Ultimately, AT can only give information and recommendations. The decision maker is still you.

    Exactly what gamer in their right mind is going to be using that 1T for gaming anyways??

    Things that make you go hmmm....

    This isn't just a comparison of Seagate to Western Digital, obviously. That's why there are several other hard drives listed in the benchmarks. The conclusion for the Seagate fits with the benchmarks: it is slower than (or at best equal to) the Hitachi 1TB drive in every single test. The only thing it has going for it is a five-year warranty, which doesn't count for much in my book. Sure, you can get a replacement drive for an extra two years, but until manufacturers start providing data recovery as part of the warranty I just don't think it's a big deal. I have dozens of hard drives from all the major manufacturers; granted, I'm not stressing every single drive 24/7, but drive failures are uncommon - whether in the first three years or at 4-5 years.

    WD has lower power (meh - 4W is *nothing* when it comes to power!), but it also has a much lower price. Seagate has a price that is $5 cheaper than Hitachi (at Newegg - though I admit I'm not sure what the difference is between the four Hitachi 1TB drives that show up). The "enterprise" version is also $25 more than most expensive Hitachi - $55 more than the cheapest 1TB Hitachi. Given the better performance (Seagate has low write performance) and essentially equal price, we'd recommend the Hitachi over the Seagate.

    I for one found the article helpful. It isn't about showing performance and choosing a winner based on speed, it is about showing all aspects of each and letting the buyer decide. Some people might want pure speed, and some might want a low power, quieter option.

    I think logic is lost on some people.

    While 4w may not seem like much to a power user, it is a big deal to someone who is building a low power system such as a VIA based system. It's obviously not going to be used for playing games but can certainly work as a file server / internet proxy. When you can get a power supply with a total output of 60w (pico 60w power supply) every watt saved brings your total lower. A lower total mean less cost for your file server / internet proxy. Reply

    I would imagine it would also be nice for a low power home file server.
    1 of these 1TB drives would use probably <1/3rd of the power of 2x500GB drives, or ~1/2 the power of another 1TB drive.
    If you have say a RAID-5 array with 5 or 6 of these drives, you're looking at a decent reduction in power which is always nice for a 24/7 machine.

    Those who have wanted to use low power hard drives on a desktop motherboard have always had the option of using 2.5" laptop drives. Reply

    Well put, Jarred.

    The Hitachi was reviewed some time ago, now, and (as you mention) its results are included in the charts. It gets mention in the conclusion as being the preferred option over the Seagate, as well.

    The Green drive does have a place as a quiet drive (the quietest of the 1TB drives tested), and it comes at a low price point. That's considerable - particularly for HTPC users, who may not appreciate the Hitachi's noise.

    For performance-oriented applications, though, it's a tough sell.

    Me thinks that this whole "green" thing from WD is because they were having issues producing a performance drive. Maybe the lower power consumption would make sense in a laptop drive, but I'd much rather have performance on the desktop.

    Seagate's ATA drives have always been so-so performers, so I'm not surprised with the outcome. However, they 5 year warranty more than makes up for it in a home server environment.

    Other drives are performing well. It's nice to have the choice. And there are uses for low-power high-capacity drives. Reply

    Your low-level results also back this up.

    There was a discussion on their forums about how it would be prohibitively expensive to produce a drive that could vary it's spindle speed due to the extra stress on the mechanism. Reply
  • Interlink - Tuesday, November 27, 2007 - link

    Anybody with a mic e.g. in his headset and a PC with microphon input is able to measure the fixed spindle speed of a WD10EACS: [url=http://forums.storagereview.net/index.php?showtopi...">http://forums.storagereview.net/index.p...c=26021&...]5400 rpm[/url]. Reply

    IBM is varying the spindle speed (Low RPM Standby mode). But only after quite an amount of idle. http://www.silentpcreview.com/article304-page2.htm...">http://www.silentpcreview.com/article304-page2.htm... Reply
