What is the difference between RAID 0 and RAID 1?
RAID 0 offers striping, which translates to better performance, but no-fault tolerance or data redundancy. RAID 1, on the other hand, offers mirroring, so the same data is available in two disks. RAID 1 is slightly slower than RAID 0 because there are two writes, but the read operations are equally fast.
