Maxtor's ATA-133 Does 160GB

Posted by CmdrTaco on from the 160-scoops-of-yum dept.

B. Galliart writes "ExtremeTech has an article about Maxtor's two new bleeding edge ATA-133 drive models coming out later this month. The most interesting of these is the 160 Gigabyte DiamondMax Plus D540X (priced around $400) which uses Maxtor's purposed "BigDrive" 48-bit address space instead of the common E/IDE 28-bit address space thus getting pass the 137GB barrier. The drive should be useable on existing computers due to a bundled Promise Technologies ATA-133 PCI card."

  1. It's the rotation speed that counts by Drashcan · · Score: 5, Informative

    For most of the applications the rotation speed is more important than the ATA standard. This determines the access time.
    I prefer an ATA-66 @ 7200 rpm above an ATA-100 @ 5400

      High rotation speed might also be bad. I've noticed that none of my 5400 rpm hdd have crashed (IBM Deskstars and Maxtors) but my 3 IBM Deskstars running at 7200 rpms have all crashed, mostly on spin-up problems.

      it is not the rotation speed that counts. rotation speed accounts for access time, but nothing more.
      cluster density is another kettle of fish, if a drive can pack twice the amount of information in half the space, you should get twice the sustained transfer rate, all things being equal.
      speed is access time.

      a good overview of rotation speed vs data density is available from tom's hardware:
      There are basically two ways to increase the performance of hard drives: increase the rotation speed or increase the data density. Increasing the rotation speed definitely enables better sequential performance, but only if you adjust the read/write mechanism accordingly.
      I dont want to take away all of tom's message, so read it further for a reasonable overview of the issues involved.

      7200 rpm is not high rotation speed - 10k rpm scsi drives are in there 3rd generation, and a few 15k rpm drives have been out for a few months now. The IBM 60gxp series is simply dead in the water, read the forums at www.storagereview.com for more info.

      I for one will never buy another high-rpm drive until they have proven them reliable.

      I've never had issues with a 7200 RPM drive, but there are some applications where they definitely don't work well. If you don't have good heat dissapation in your case, don't get a 7200 RPM drive. They produce much more heat than a 5400 RPM drive. 7200 RPM drives are known to not work well in a TiVo. The heat they put out tends to cause severe stutter problems, among other things.

    With 8 of those drives (which would fit into a regular PC with RAID controler) you could finally reach a Terabyte. Gee, now no point in compressing those CDs into MP3, might as well keep them in clean WAVE files :)

  3. Extended LBA already part of ATA-6 spec by arafel · · Score: 3, Informative

    "Extended" LBA commands are part of the ATA-6 standard (or proposed standard, or whatever it's marked as today). They give 48-bit address spaces. I suspect Maxtor is using this; if not, hopefully it will be soon.

    Hope that's helpful.

    ATAPI still has a limit of 2 devices (master/slave) per controller. Ultra-SCSI is 15, not including LUNs.

    ATAPI devices are still limited to hard drives and CD-ROMs (via a hack). SCSI handles scanners, tape drives and other devices as well -- it is much more generic.

    ATAPI still causes performance degredation when you are accessing the master and slave on the same channel at the same time. SCSI does not.

    How quickly do we forget that CPRM proposal was defeated and Maxtor was one of the high-profile companies to vote against it. IBM, Microsoft, Iomega and others wanted to push it through.

  6. "Maxtor Big Drive" = ATA/ATAPI-6 by Otto · · Score: 4, Informative

    Maxtor's so called Big Drive technology is no more than an implementation of the spec. ATA/ATAPI-6 specifies a 48 bit address scheme, giving a new upper limit of 2^48*512 bytes, or 128 petabytes.

    Also, the limitation is not 137 GB, it's 128 GB. And Maxtor's new drives are not 160 GB, they're slightly more than 149 GB. These mistakes are what happen when you start believing "drive manufacturer math".

    Buy 2 and run them in raid-1. If you're paranoid, buy 3 at the same time so you have a spare
