RAID 10 Data Recovery

RAID Data Recovery Services

RAID 10 data recovery (RAID 1 + RAID 0) is a combination of RAID 1 and RAID 0. RAID 10 stripes the information and then makes a copy of the stripes. A RAID 10 configuration first divides the information across the disks, and then it copies the stripes.

RAID 01 (RAID 0 + RAID 1) makes a full copy of the disk and then stripes it. Since the striping occurs after the mirroring, all of the information is on both the disks rather than split up between the disks.

Advantages of RAID 10

  • If something goes wrong with one of the disks in a RAID 10 configuration, the rebuild time is very fast since all that is needed is copying all the data from the surviving mirror to a new drive. This can take as little as 30 minutes for drives of 1 TB.

    Disadvantages of RAID 10

  • Half of the storage capacity goes to mirroring, so compared to large RAID 5 or RAID 6 arrays, this is an expensive way to have redundancy.

    RAID Failures

    •   RAID controller failure
    •   Rebuild failure
    •   Damaged striping
    •   Multiple drive failure
    •   Drive not detecting in BIOS
    •   Configuration damage or corruption
