RAID 6 storage arrays are starting to become more popular, as the increased size of disks and rebuild times, have also increased the risks associated with RAID 5 arrays. RAID 6 combines redundancy and speed with a small trade-off in the efficient use of storage.
The RAID 6 disk configuration is a set-up where the data is striped along with distributed parity information across a minimum of four hard disks. The striping gives you speed and the distributed parity which is stored on two drives, provides enhanced fault tolerance. Should one or even two of the disks fail, data on the failed disk or disks can be rebuilt from the parity information stored on the remaining working disks.
When a RAID 6 array fails, RAID 6 recovery is still possible because of the redundancy capability. However, if more than two disks in the RAID 6 array fail at the same time, the missing data from the failed disks can not be rebuilt without expertise and RAID 6 data recovery experience.
RAID 6 data recovery requires the thorough understanding of the RAID disk sequencing, RAID stripe lengths, XOR parity and Galois field parity information, along with experience in file system and data structures.
DiskEng RAID 6 data recovery specialists can recover your data from RAID 6 storage arrays. For many years now our RAID recovery specialists have been developing the techniques required to recover data from your RAID 6 array.
