RAID 10 Recovery


Also known as RAID 0+1, the RAID 10 level array combines RAID 1 and RAID 0 architecture to provide full redundancy and data striping. Although this reduces the overall capacity available to only half, it provides an extra element of data security.

This architecture allows the RAID to operate in degraded mode following the failure of a single disk and even a second as long it is not the other drive in the failed mirrored pair. If both drives in a mirrored pair fails, the RAID will fail and most likely go offline.

As with all RAID systems providing redundancy it is essential that the failed drive is immediately replaced and the rebuild initiated, so as to decrease the risk of a second failure causing the array to go offline. A good backup strategy should also be used as insurance against such a failure occurring.

Despite the robust nature of this type of RAID array, our engineers have seen a number of examples arrive following the failure of both drives with a single mirrored pair. The use of mirrored pairs increases the chances of recovering all the data from the array following such a failure.

Any type of failure, be it physical or logical damage can be recovered by our data recovery engineers. Most RAID 10 arrays arrive as the result of multiple hard disk drive failures, although our data recovery specialists have recovered data from several which were repartitioned or reformatted.
