The card I used was a the TX2 without RAID for the $28 price. I used Linux
software mirroring and hdparm reported speeds of >30MB/sec using my 2 IBM
40GB ATA100 40GB drives. This was on a Duron 800 processor with 512MB RAM.
I expect that there is some CPU overhead to do the mirroring, so if you're
using a slow or saturated CPU, this may not be the right answer.
On a side note, I also bought a Promise TX2 RAID controller for use in
Win2K. It's working fine too but I haven't done any performance tests to
see how fast it is.
Seasons Greetings!
