This is probably the bazillionth thread on RAID setups and whatever, but I have a 2008 Octo mac pro and I want to set up a RAID 1 with my hard drives. I hope experienced users can help me out with some questions. 1) I know I'm going to need to get a RAID card, are they any good (preferably cheaper) equivalent cards compared to the Apple RAID card? 2) Is it advisable to get two identical hard drives, (brand, model etc.) or is it fine to just use the same capacities? 3) If one hard drive fails, is there an indicator that a drive has failed? 4) Finally, if a drive does fail, how can I go with a restore or replacing the faulty drive? Any help would be greatly appreciated, and 100 internets to anyone with some really helpful information!
