Performance seems as good as hardware-based RAID solutions. Under 5.1-RELEASE I've been told that the boot partition can be on a vinum volume; in 4.8 that's not possible but I've used extra space to create several duplicate boot partitions. I've always used SCSI, but the low cost of ATA devices would certainly make me look at them today. I've also been told that you'll need as many ATA busses as drives, since slave devices slow down ATA speed. Mike Squires
