I have two 8-port ones i a machine with 500GB hitachi drives, runs ok, but NCQ 
needs extremely new firmware from hitachi. I've so far tried, among other 
things, raid0, raid5, lvm stripe over devices, heavy I/O while rebuilding, .. 
everything but two performance problems looks fine (#1 ext3 sucks on 3ware 
raid5, #2 I can't get good read performance on two raid5s in a lvm stripe).
