SCSI vs. IDE In The Real World

Posted by timothy on from the safe-to-go-back-in-the-water dept.

An anonymous reader writes "Gerard Beekmans has a really good comparison of the speeds of IDE and SCSI drives up over on devchannel.org. Should help put an end to the myth of IDE erasing SCSI's speed advantage." Note that Beekmans' test handicaps the SCSI disk a bit, with interesting results. (DevChannel, like Slashdot, is part of OSDN.)

  1. scsi and laptops by KhanAFur · · Score: 3, Interesting

    This article show that scsi drive have a considerable advantage over the same spindle speed of ide drives. Laptops tend to have slower drives. Has anyone considered using scsi drives in laptops?

    Does anyone know fo laptops that use scsi drives?

  2. You get what you pay for. by Sheetrock · · Score: 4, Interesting
    Besides the speed advantage, SCSI drives also typically last two to three times longer than their IDE counterparts, and generally go through more rigorous testing.

    Tape drives are like this, too. They look the same, they act about the same during the write process, but the cheapie drives that come with some servers will fail to reread the tapes if they're reused as constantly as they are in most businesses (who, on average, reuse the same weekly tapes for a full year or more!). Better to put the money into a DLTtape solution than to rely on what's bundled with the server.

  3. Holy war? by BenjyD · · Score: 4, Interesting

    What is this? Holy war week on Slashdot? In the last week or so we've had stories on BSD vs Linux, Linux vs Solaris, PHP vs Java, Exchange vs Sendmail , x86 vs PPC and now IDE vs SCSI. All that's missing is Vi vs Emacs and I think we'll have pretty much every major computing disagreement covered.

  4. SCSI over NFS better than Local ATA for me! by MarcQuadra · · Score: 4, Interesting

    I get better real-world performance from my Ultra-2 SCSI drive _over NFS_ than I do for my local ATA/100, and the SCSI disk itself is about 5 years old.

    That says something.
