    Seagate 1TB 2.5" drives are coming up, no word on whether they are 9.5mm or 12mm

    rule of thumb:

    single platter = 9.5mm
    dual platter = 12mm

    There are exceptions, but not many.

    I thought 3 platter drives were the primary reason for 12.5mm, like WD's 1TB drive which has 3 333GB platters?

    Where on earth did you hear that from?!

    Single and dual platter drives are 9.5mm, three platter drives are 12.5mm. Samsung's HM500LI is one of those rare three platter drives that are 9.5mm.

    That's your thumb. Sorry you have an usual thumb.
    3 platters are 12mm. The current generation 2 platters are 9.5mm.

    Not necessarily
    Samsung packed three platters in there HM500LI, which was a 9.5mm thick drive

    But usually three platters means 12.5mm

    That 1Tb seagate is guaranteed to be a 12.5mm thick drive. The ability to pack 500gb on a double sided platter simply isnt there yet

    I was more hoping that Seagate had managed to accomplish a miracle and squeeze it into the 9.5mm form factor, although that would rock if the somehow cracked the 500GB barrier this early.

    I agree with K-TRON. It is almost sure that these drives will be 3-platter versions and 12,5mm thick unless they manage to fit 3 platter in a 9,5mm case like Samsung did.

    What I don't like is that they try to reach first the 1TB "cool" size instead of the intermediate 640 and 750GB. From a technological point of view they are able to give us a 2 platter 9,5mm 640GB drive immediately and I know that they announced it already but haven't made it truly available to public.
    As far as I am concerned they should abandon completely the 12,5mm drives. They must not exist in a world where all notebook makers try to make thinner and lighter cases.

    With only 8MB of cache, I don't think these drives will be all that fast (same goes for the WD ones.) They are probably meant for storage use, as in storage applications the 12.5mm height and small cache might not be that much of a problem.

    In what situations would you actually notice the 8MB being a bottleneck to the system? All (if not, almost all) 5400RPM drives have no more than 8MB of cache as far as I know. I don't see how 12.5mm height and small cache have any relation.

    Probably intense database-type operations would require a fairly large cache. I'm not completely sure though.

    As for the 12.5mm drive height, with a laptop you would need to increase the thickness of the chassis slightly to get it to fit, which isn't really an option as most people are buying ultra-slim laptops these days. However, you can make a 12.5mm-high drive enclosure and put a WD10TEVT or whatever in it. That would still much smaller than a typical 3.5" 1TB drive+enclosure, not to mention using less power (one USB port instead of one USB port and power adapter,) and it'd only be a little bit thicker than the normal 9.5mm ones. Of course 3.5" drives store up to 2TB, but for most people 1TB is enough, and the fact that you can now get that capacity in a much smaller size and be able plug it in with one cable is more appealing.

    That's what I think, anyway...

    You do realize that there are users out there with the ability to accommodate a 12.5mm hdd. I, for example, can handle 2 of them.

    The question I have is this, can the Seagate hdd be harvested from the Seagate external drive casing and put into a laptop that can handle a 12.5mm drive? The new WD's in the external casing have the SATA connector removed and the USB connector is soldered directly the drive, which means you cannot harvest the drive for other uses.

    WD does sell a 1tb version that is outside of a case and does have a SATA connector, but it's not available until after Christmas.

    I answered my own question. No, you cannot remove the new Seagate hard drive from the casing and place it in a computer that can handle 12.5mm drives. The Seagate drives are even bigger then 12.5mm. I think they have 4 250GB platters. The picture shows a Seagate 1tb drive on the left next to a Hitachi 500gb 12.5mm drive.

    they're just cheating.
    they can make a 2tb 1.8" disk right now, they just have to make it fat enough.

    so we should stop naming disks by their diagonal size.. what's next? volume? :)
