RAID levels
Cards in this deck (17)
- 1Block level striping only, the spread read/writes across the drives, making a fast system, no toleranceRAID 0
- 2Mirroring only to create identical copies of data on the other drives, all but one drive can failRAID 1
- 3Bit level striping with hamming code error correction to enable rebuilding data with spread read/writes, one drive failureRAID 2
- 4Byte level striping with parity error correction to enable rebuilding data with spread read/writes, one drive failureRAID 3
- 5Block level striping with parity error correction to enable rebuilding data with spread read/writes, one drive failureRAID 4
- 6Block level striping with parity error correction to enable rebuilding data with spread read/writes, one drive failure, more advanced than RAID 4RAID 5
- 7Block level striping with double parity error correction to enable rebuilding data with spread read/writes, two drive failuresRAID 6
- 8What levels can have 2 or more drives, minimum?RAID 0 and RAID 1
