You are about to bring a new server online, and you want the most efficient disk configuration possible for your new system. Select the proper RAID array on which to place your files for optimum performance and fault tolerance. Choose from RAID 1, RAID 2, RAID 0, and RAID 5:
RAID 5: Data Files
(OS and Binaries should be on a mirror. Transaction logs should be on a mirror because they need the sequential write speed that a mirror provides. Data files should be on a stripe set with parity, for the read speed it provides.)
