I've recently had a little trouble buying a hardware ATA raid card (I was shipped an incorrect model and lost out about GBP 100!) so until then I'm software only. I looked at (I think) raidframe (?) and this /appeared/ to support this functionality but I wasn't sure if it was something Vinum was also able to do. It seems you have clarified this for me.
