My hard drive claims to be ATA100; the motherboard claims UDMA 33/66 IDE. I'll admit that I know nothing of the relationship between ATA and UDMA, but I had assumed that the numbers were comparable, especially since most hard drives seem to be ATA66. Can you enlighten me?
From my experience the differences between ATA and UDMA are a matter of semantics. I do beleive that the marketing departments of the various HD makers use this term ad-hoc (though I have read that there is a difference from a technical standpoint) For example mobo makers refer to their IDE channels as UDMA and the HD makers will use both terms (ATA and UDMA).
So am I likely to gain anything by hooking my ATA100 hard drive to an ATA100 controller rather than hooking it directly to an UDMA 33/66 mobo? Paul
