5 Cards in this Set

  • Front
  • Back

RAID 0

Writing to 2 disks to increases write speeds but all data will be lost if one disk fails.

RAID 1

Mirrored units. Decreases write speeds but no data will be lost unless all disks fail.

RAID 5

Data blocks are striped across the drives and on one drive a parity checksum of all the block data is written. increased wroted speeds and no data is lost if 1 disk fails.

RAID 6

RAID 6 is like RAID 5, but the parity data are written to two drives. That means it requires at least 4 drives and can withstand 2 drives dying simultaneously.

RAID 10

Combination of RAID 1&0. Striping the data across 2 drives and then mirroring those drives.
