''After a server upgrade our client's RAID 5 volume became inaccessible. I tried to recover the data with several data recovery tools, with no success. We decided to try remote RAID Data recovery at RAID Recovery Online. Most of the data was recovered within 24 hours and the rest was available shortly after that!''

RAID 5 distributes data across several disks while protecting the data against a
single disk failure. Storage performance increases with higher read and write transaction
Data is divided into blocks, and each block is stored on a different drive.
Parity block is stored on a single drive and distributed among the disks.
efficiently utilizes the capacity of the disks, reducing the capacity by one disk.
In case of a single disk failure, the array can be rebuilt. However, quite often
the rebuild process fails, or is not performed before a second disk fails, and all
the data become inaccessible.
