what is the advantage of RAID

Answer Posted / raja

Higher Data Security: Through the use of redundancy, most
RAID levels provide protection for the data stored on the
array. This means that the data on the array can withstand
even the complete failure of one hard disk (or sometimes
more) without any data loss, and without requiring any data
to be restored from backup. This security feature is a key
benefit of RAID and probably the aspect that drives the
creation of more RAID arrays than any other. All RAID
levels provide some degree of data protection , depending
on the exact implementation, except RAID level 0 .
