Okay, so the server is currently set up in the following way, using disk utility software RAID when RAID is mentioned. The computer has 5 hard drives installed (using one of the optical drive bays for a HD) Drive 1 and Drive 2 are RAIDed together in type 1, and are the system/server disk. Drive 5 is a media server disk (movies, TV shows, music) Drive 3 and Drive 4 are RAIDed together in type 0, and are a Time Machine backup disk for both of the above. It's critically important that the system/server portion never goes down. It's being used for web serving, email serving, calendar serving, etc. I've heard that Apple's software RAID isn't the most reliable thing out there, so I'm considering adding a PCI express hardware RAID card. I believe I'd only need it to be 2 channel to handle the two drives, but if it's only minimally expensive to go to 4 channel and would allow me to do Drives 3/4 in type 0 via hardware, so much the better. So, my questions are: 1) Is Apple's software raid actually reliable? If so, when a Drive 1/2 fails, would popping in a new one automatically restore it to type 1 redundancy? 2) What are the best CHEAP Mac compatible PCI express RAID cards? I really don't need high performance (speed) at all. 2 channel is all I need, but if 4 is only a little more I'd go with it (assuming a 4 channel lets you have 2 different raid configs) 3) How do you actually set up the RAID in the Mac OS? Disk Utility still? 4) In the Time Capsule, Apple claims to use "Server grade hard drives for extreme long life". Where does one buy these hard drives? Again, I have no real speed needs for Drive 1 and 2, so I'd pick up two of those if I could find them. 5) Also considering a SAS card, if there's anything remotely price reasonable out there. Seems like that may be necessary to get a drive designed for reliability. Are there any reasonably priced SAS cards out there? Thanks in advance!
