Hi Kam, I'm using a 3ware Escalade 7810 card with no problems at all. It's the 8-port 64-bit version. I have 5 drives in a RAID5 with 1 hot-spare attached to it. Not only does it have great drivers (works out of the box with FreeBSD), but you can also get the monitoring/maintenance daemon for FreeBSD. I recommend them for anyone who needs a large amount of cheap storage (we've got 320Gb). Also, I heard that Yahoo use the 3ware cards in their servers also, so they must be good! :) Cheers > Though I think vinum is about the best way to implement mirroring two disks > under FreeBSD, I have since seen that I really should be investigating > hardware based raid possibilities.
