I guess that the original questions have not been asked, so the answers really depend: Why raid? is the complexity of doing and maintaining raid worth the objective? I can give good arguments for NOT raid, it just depends on what YOU want Why LVM? That lets you dynamically extend your disk size The cost is reliability If cost and size are constraints the new 300G WD disks, heck even the Seagate 1T disks are cheap and relatively cheap. Me I choose expensive! WD raptors in a LVM for the server, with 2/3 times a week BU to 300G WD. I can restore my server in an hour or so, that suits me, and I've not needed to do so in 3 odd years.
