Seagate Claims 2.5" SCSI Drive is World's Fastest

Posted by ryuzaki0 on from the like-a-supersonic-record dept.

theraindog writes "Seagate has announced a 2.5" SCSI hard drive that spins at an astounding 15,000RPM. The Savvio 15K is the first 2.5" hard drive with a 15K-RPM spindle speed, but what's more interesting is that Seagate claims it's the fastest hard drive on the market. Indeed, the drive boasts an impressive 2.9ms seek time, which is more than half a millisecond quicker than that of comparable 3.5" SCSI drives. The Savvio 15K also features perpendicular recording technology and a claimed Mean Time Between Failures of 1.6 million hours."

    They just keep chipping away at that Von Neumann bottleneck.

  2. How many seek/ECC errors does it give?? by madhatter256 · · Score: 2, Interesting

    I don't know about you, but every single Seagate HDD I've tested, both brand new and used give a lot of seek errors way above the SMART margin if you run SpinRite 6.0. I've experienced Seagate HDDs simply failing because of too many logged seek/ECC errors and Windows will freeze as it initially loads. I have never seen this type of perfomance with Samsung, WD, Fujitsu (SCSI) and Hitachi HDDs. Sure, not all hard drives are perfect but in my experience, Seagates have always given me problems to the point where I simply don't recommend them anymore.

      I've only had 2 of more than 12 WD drives die; one was because it fell while running from more than 8 feet off the ground, the other was insufficient cooling. I've had 5 of 6 Maxtors die, and I'm 4/4 with IBM drives deaths. 0/4 for Seagate, but they are my most recent acquisition.

      You're right, everyone has stories. I have 2 4 drive WD arrays that have been around for 3 and 2 years, no failures there. But I wouldn't trust any data to an IBM or a Maxtor drive.

      And here is some anecdotal evidence to counter your claim that Western Digital drives suck.

      I have 4 250gig WD SATA drives (all model WD2500KS). I've had 2 of them for a year and not a single issue. Recently I bought two more and I've had them set up in a RAID0 array for the past 3 months without any problems. I use Acronis True Image just in case, but I haven't had to restore any images yet... IMO, these western digital drives are great, they are fast and quiet, and they cost less than $90 a piece.

      One major problem I've seen is people with crappy power supplies causing hard drive corruption. If your power supply isn't able to keep your hard drive(s) powered correctly, you can have corruption, blue screens of death, etc.. It's pretty important to have a good PSU that delivers stable power across all rails. A bad power supply won't be able to keep your drives powered at all times, causing data loss, etc..

  3. the edge of the plate spins 50 meters a second! by dgerman · · Score: 4, Interesting

    This is insane. The edge of the plate travels 3km a minute:

    2.5 inches diameter => ~20cm perimeter at 15k RPMs => 3km/Minute => 50m/s => 180 km/hr.

      That's nothing; in terms of rotating things, flywheel batteries are much more interesting. They have achieved a velocity of 2km/s at the edge. (about Mach 6)

    I guess what's new is the 2.5'' form factor. Smaller drives should be generally faster due to increased density, but they get a bad reputation from laptop drives with really low RPM.

    Most use IDE or SATA.

    I think you mean PATA or SATA. IDE stands for Integrated Drive Electronics and simply means that the controller for the hard drive is on-board, and requires a suitable host. PATA and SATA are simply two different for the host to communicate with an IDE drive.

    We are used to equating IDE and PATA because PATA was the only widespread method of connection between the host and the drive. So while we all understand what you imply by saying "IDE or SATA", it is more correct to say "PATA or SATA". In fact the term PATA was coined only after the invention of SATA.
