not true. RAID 5 is the worst for dis disk performance. it writes all data accross all drives, with parity. This allows an entire drive to die and the system will work around it, and when replaced, the drive will be automatically rebuilt.
RAID 1 (mirroring) is WAY faster for reading data (it can choose between two drives) RAID 0 (Striping) is the fastest all around.

A popular combo (for DBs) is RAID 0+1
