ATA 100 on a proliant server?

  1. ATA-100? Are you sure? ATA-100 is a little long in the tooth.

    IDE has grown up. The only real difference between SCSI and IDE drives
    is the electronics board. The drives are often identical (it's been
    that way for quite some time). IDE is now faster and cheaper than
    SCSI, so there is no reason for the expense of SCSI on a small system.
    My Tyan 2875S (single-processor version of a dual Opteron server board)
    has IDE (2) and SATA (4) channels.
  2. Really?

    The above one is about twice the performance (half the access time,
    half the latency, twice the spindle RPM, half the seek time, twice the
    sustained transfer rate) of the closest Ultra ATA/100 or SATA/150
    drive from the same manufacturer. Only capacity tends to be lower than
    for the cheap "pack rat" consumer drives. Some of them are still being
    made in 5400 RPM.
    Just as most people would be perfectly fine with 1GHz rather than 3.
    Or a Chevy rather than a Z-4.

    There's very little difference in IDE and SCSI drive reliability these days.
    Indeed I had 2 consecutive brand new Seagate Barracuda IVs ( SCSI ) fail in just
    a few months some years back.

    The speed of IDE is also way ahead of early implementations of SCSI anyway
    although high end SCSI still has the edge on data transfer rates.

    Was reading the article about the proliant server. I was shock that they
    offer ATA100 on the drive system. I know Ok so its raid ATA but my
    impression has always been that IDE should be no where near server
    platforms. Anyone have more experience with this? Do these server machines
    running ATA stand up well in the real world.
