Some RAID cards are substantially slower at RAID 5 than 0/1/0+1. The
3ware ATA RAID boards are excellent, for example, except at RAID 5.
They now produce a couple of boards with more CPU power or different
ASICs, or whatever, to make up for this shortfall. But they are more
IIRC the 7x10 series is quite slow at RAID 5, but the 7x50 series
improved upon this greatly. My source is www.storagereview.com, though,
I do not use any of their newer RAID 5 boards.
