Isn't a 10 or 24 spindle RAID 5 array awfully likely to encounter a

that's why you should use raid6 (allowing for dual failures)
You can have as many parity drives as you want with RAID 5 too.
you can? I've never seen a raid 5 setup with more then a single parity
dirve (or even the option of having more then one drives worth of
redundancy). you can have hot-spare drives, but thats a different thing.
what controller/software lets you do this?
