This is intriguing. Where would I look to get info on this? I'm running XP
Pro.

Of course, I now seem to have mismatched HDs. The primary is an 80gb
Hitachi which PCPitstop show as having about 2.3mb uncached throughput and I
just added an 80gb WD which is showing 6.1 gb uncached throughput.
Strange...

You don't even need a RAID card - you can mirror drives under Windows
NT/2000/XP without any hardware controller.
