RAID 10, also called RAID 0+1, is a RAID configuration which combines data striping with mirroring. This allows for extra redundancy and speed over a straight mirrored pair. The downside of this configuration, over a RAID 0 striped array, is the decreased capacity.
RAID 10 configuration does however, provide a very high level of redundancy, as the data stored on a disk is duplicated exactly onto another disk. This allows for the possibility of more than one disk to fail, and still have an operational RAID.
RAID 10 arrays are set-up to store data across multiple disks and mirror this onto another set of multiple disks. Although this gives very high levels of protection against data loss, this type of configuration is a very inefficient use of disk space, where half the available storage is dedicated to mirroring.
Data loss from RAID 10 striped mirrored configuration is still a possibility, if disks containing the same data, fail on both sides of the mirrored pairing.
We can still recover your data from RAID 10 failures. Once the failed source and duplicate disks are received into our laboratories, our data recovery specialists can quickly determine the best options, and attempt a full disk recovery on the RAID 10 striped mirror disk set.
Although RAID 10 provides 100% redundancy, RAID 10 systems must still be used with caution. We have recovered data from many types of RAID disk failures with some from RAID 10 striped mirror set-ups.
From our disk recovery services, we understand that RAID storage disks can still fail in a number of ways:
- Power surge
- Multiple disk failures
- Damaged operating system
- Corrupt file systems
If you require recovery of data from a RAID 10 system, we can help. Contact our data recovery specialists to discuss your problem.
