I'm totally new to RAID so I appreciate the help. I learned a little from reading previous threads. I have 3 x 750GB Seagate drives that are just begging for some tinkering. I've heard a lot about RAID, but I have no clue what I'm doing (and that scares me). What should I do? I can't decide which type I need, if any. I'm mostly concerned about Leopard. Will Time Machine render my mirrored drives useless? What about striping? Concatenated? Should I use my boot drive in the array, or is this a bad idea? What's the difference between striping 2 drives as opposed to 3 drives? Thanks!
