Here is a nice roundup of IDE-RAID cards. I've now confirmed that I'll be getting a 3ware 7500 soon.

by what I saw in there the 3Com is the slowest one.
Anyway I have a "software controlled" Adaptec 1200A and it's quite efficient and the CPU time taken is at about 5% in a Raid0 configuration

It (3Ware) was slowest in some areas, but faster in others. It has stellar read times. And it supports RAID 10.Comment

Not very informative on streaming sequential writes & reads, which is the most important for those doing video. Most RAID5's can only muster about what a single HDD can do regarless of how many drives are in the array. My SX4000 RAID5 delivers well over 90 mb/s consistantly on both sequential reads and writes.

If I remember correctly there is somekind of RAID bug in XP that affects performance.....
And they used that OS as test plattform....If there's artificial intelligence, there's bound to be some artificial stupidity.
