Seagate Claims 2.5" SCSI Drive is World's Fastest 218

Posted by ScuttleMonkey 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."

      Generally speaking, Seagate's Savvio line of HDDs are intended for server and enterprise storage (read: SAN/NAS) use, not for laptop use. 2.5" hard drives are particularly useful in some compact storage arrays or in blade servers. They probably consume wayyyy to much power for your average laptop. Also, most laptops don't feature SCSI storage. Most use IDE or SATA. It's possible that Seagate could, in the future, come out with a SATA version of this drive, but I don't think it's likely given the power consumption and heat characteristics of 15K RPM drives. Seagates laptop drives don't even break 7.2K.

        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

      The term "von Neumann bottleneck" was coined by John Backus in his 1977 ACM Turing award lecture. According to Backus: "Surely there must be a less primitive way of making big changes in the store than by pushing vast numbers of words back and forth through the von Neumann bottleneck. Not only is this tube a literal bottleneck for the data traffic a problem, but, more importantly, it is an intellectual bottleneck that has kept us tied to word-at-a-time thinking instead of encouraging us to think in terms of the larger conceptual units of the task at hand.

    • Can anyone explain to me why SCSI drives always seem to be lagging IDE in terms of capacity? Does the increased rotational speed make them unable to discern smaller features on the disk?

      SCSI drives, while using a 3.5" form factor, use smaller platters inside so that they can spin at the higher rotational speeds. Thus, lower capacity. AFAIK, SCSI drives use the same bit density per square unit of linear measure as SATA/PATA drives.

      The people buying SCSI drives are going to be attaching them as part of a honking great array. The biggest concern is speed, and you get that by spreading the data across as many drives as you can.

      73GB doesn't sound so bad when you multiply it by 12 for the number of disks you plan to use.

      The main limitation for bit density on a high speed drive is the channel data rate (since you can't use anything but standard CMOS in a low power, high volume, low margin product.) If you spin faster, at a given maximum bit rate, you lose bit density. Also, for faster seeks, you have to put down more servo information (otherwise you may not see any servo bursts for some time while the head is crossing only data.)
      You can generally stuff more data on a platter by spinning it slower. That's why basic 2.5" dri

    • Higher capacity = lower speed. Most SCSI drives sacrifice capacity for higher speed.

      They probably have smaller platters, and also, less total platters in the drive. This means the drive has a smaller capacity, but the read head has the advantage of not having to move as far across the disk to read data, reducing latency and increasing performance (AFAIK).
  • Putting it in a 2.5" package is pretty cool, but there have been 15k rpm 3.5" drives since the early '90's, as far as I recall. My desktop Dell has one. Here's a review of three popular ones [xbitlabs.com]. And, for the record, the edge velocity on a 3.5" is considerably higher than a 2.5" for the same rpm.
    Correct me if I'm wrong here: 3.5" x 3.14 = 11 cm circumference, *15,000 = 1.6E5 cm/min, /100 = 1.6E3 m/min, *60 = 98910 km/hour.

      you are wrong... your figure is hundreds of inches/hour, not km/hour. 3.5" * pi * 2.54 = ~28cm circumference. *15000 = 4.2e5 cm/min. /100 = 4.2e3 m/min. /1000 = 4.2 km/min. *60 = 251 km/hour. the edge velocity for a 3.5" as compared to a 2.5" drive is simply the ratio of their diameters.
  • Doesn't this faster speed make the HDD make more heat and use more power?
    • Yes, SCSI drives run hotter and use more power than a consumer drive. A typical consumer drive runs at 7200rpm, while a 15k SCSI drive is over double that, at 15000rpm (they are quite a bit louder too).

      According to this review [techreport.com], the Savvio 2.5" 15K drive uses less power than older 10K drives. Also, it is twice as quiet as previous 10K models, that's pretty impressive IMO.

      These drives aren't cheap either, the 36GB version goes for around $450 while the 73GB version goes for around $840.
