Everything here is theory, so YMMV...
The Deskstar 75GXP's are great drives. I have no idea of actual benchmarks,
but a 7200-rpm drive with a 2-MB buffer sounds great, and IBM has
traditionally made fast drives. I would actually invest the money in
switching to them, but this is a feeling and I have no data to back it up.
I would, however, note that perhaps the most significant speed benefit
should come from increasing the number of drives, shouldn't it? Given
RAID-0 characteristics, using three drives or more should provide
performance benefits above what you'll get from a single drive. You might
want to take into consideration the idea of buying either three IBM drives
or two more of what you already have.
I got ahold of four identical 20GB drives for chump change, and when I get
home I'm going to set up my personal box with all four doing RAID-0, also
on a KT7A-RAID. I'm hoping my theory is right and the thing smokes...
