Mac Pro RAID5 Questions

[Chaszmyr]

I'd be using Apple's RAID card in a Mac Pro with a 4 drives. So the questions are:

1. Are there any disadvantages to using RAID5 as a bootable volume?

2. Would a controller failure be a realistic possibility, and if there was a controller failure would turning off the system and replacing the RAID card be sufficient to salvage the array?

3. Would it be feasible to migrate the whole array to a different computer in the future?

Thanks in advance

Normally you can back up the RAID controllers configuration. Atleast thats how it works on the servers i have administrated. So using that small backup file you could restore a replacement RAID controller. Or move the drives to a different system. However, i am not sure how this works on macs with this card.

PS another guy is having problems with his new RAID card could you head over their and help us out with some questions?
