Hi. I have found a nice little two port RAID card (supports 250Gig)....my question is this... I want to add two identicle 250Gig's in mirror, I also have a spare 160Gig. What would be the performance effect of having the two 250Gig drives on the same channel (IDE 1) as primary and secondary. Then using the odd 160Gig on IDE 2. Thanks.
