they have two different Western Digital 60 GB Scorpio drives. One
says it's ATA-6, and the other says it's IDE Ultra ATA 100. They are
two separate drives - the ATA-6 one has a 2 MB cache, and the IDE has
an 8 MB cache.
I went to Wikipedia to look at the differences with the interfaces, and
it *appears* that the two
interfaces are the same... It is that true?
ATA-6, Ultra ATA/100
UDMA 5 (100)
AKA Ultra DMA 100
48-bit LBA, Device Configuration Overlay (DCO),
Automatic Acoustic Management
Does is matter which drive I use for the replacement? I would prefer
the one with the 8 MB cache, naturally.
The original IBM Hitachi drive just says IDE/ATA on it.
Thanks for any help with this.

Re: Replacement HD - Interface question
That is not universally true. There are 7200 rpm drives that use less
than some 5400 rpm drives. Although the average 7200 rpm drive probably
uses more power than the average 5400 rpm drive, because the range for
both types of drives is so large, you can't generalize on power
consumption or heat, you can only compare two specific drives.
