most of mnc used hdd raid. this is the techonolgy used for

there software available raid are raid 0, 1 ,2,3,4,5,6

Answer / mcmarc
redundant array of inexpensive disk, this is used for data
distribution and data redundancy.
levels
0 data distributed (no redundancy)
1 data distributed across disk and having a mirror of each
disk, its expensive
5 data distributed with parity

Answer / manoj
Raid is Redundant Array of Independent Disks/Device.It is
Technology to improve Disk read & write Performence and
FaultTolerance., By adding new disk u can recover data if
one of disk goes down / fails. parity is a calculated
technique to rebuild data from disk fails.
levels in Raid
0 - stripping
1 - Mirroring
3 - Striping with Parity
5 - Striping with Parity with more fault tolerant widley
used.
