It's going to take a lot more good points to convince me to use a RAID card over software than the DLT/DAT thing the other day.

Um, think about it Rob. This is a MICROSOFT implementation of software RAID we're talking about.

Last time I tried to use a Microsoft software RAID, I lost all the contents of the disks when one of the disks failed. Fortunately, I'd backed them up the night before onto DLT...

Also think about speed. A hardware RAID controller will be hella faster. It'll have onboard cache and such.
