Overview of
RAID 5 is a storage performance, data security and storage costs into account storage solutions. RAID 5 can be understood as RAID 0 and RAID 1 to compromise. RAID 5 can provide data security for the system, but the low level of protection than Mirror disk space utilization and higher than the Mirror. RAID 5 and RAID 0 approximating having data read speed, but with an additional parity information, the data writing speed slower than write operations on a single disk. And because the multiple data corresponding to a parity information, RAID 5 disk space utilization than RAID 1 high storage costs are relatively low, is the use of more of a solution.
RAID4 as RAID5 and data in units of blocks distributed to each drive. RAID 5 data is not backed up, but the data corresponding thereto and the parity information stored on each disk consisting of RAID5, and parity information, and data corresponding to each stored on a different disk. When a RAID5 disk data corruption, the use of the remaining data and parity information corresponding to recover corrupted data.
