data in most companies has led to an explosion of storage
systems and hard disk drives. It's statistically proven that as
HDDs proliferate so will the number of hard disk drives
failures, which can lead to lost data. Analyzing what happens
when a HDD fails illustrates the issue: 1) A hard disk dive
fails 2) The drive must be physically replaced, either manually
or from an online pool of drives. 3) Depending on the RAID set
level, the HDD's data is rebuilt on the spare: 4) The time it
takes to rebuild the HDD's data depends on the hard disk drive's
capacity, speed and RAID type. - SATA drives typically have a
rated - non-recoverable read error rate of 1014: roughly 1 out
of 100,000,000,000,000 bits will have a non-recoverable read
error. This means that a seven-
