RAID 5 Data Recovery

Recovery For RAID 5 Systems

Redundant Array of Independent Disks (RAID) is a technology that combines multiple physical disk drives into a virtualized drive that uses disk striping and parity data across multiple drives. This improves both speed and safety versus having several drives run independent of one another. A simple definition of disk striping is the distribution of blocks of data over multiple drives. A RAID 5 volume is one of the most popular variations of RAID because it distributes striped and parity data over all disks.

How RAID 5 Works

RAID 5 requires a minimum of three physical disks. Parity and striped data is written to each disk. The parity data written to each disk acts as a failsafe. If one disk becomes defective, the other two disks will operate, although performance will most likely be degraded until RAID 5 data recovery is completed.

How RAID 5 Arrays Can Fail

RAID 5 fails when one or more drives in the array fail. When one or more drives fail, a common response among network engineers is to hot-swap out the defective drive and let the array rebuild itself. Adding a new drive back into the array may work, but it may also cause additional problems that can put your data at risk.

How we Can Help

WeRecoverData.com is a world leader in data recovery. When a RAID 5 unit fails, it is important to have an image of the functioning drives. A simple restore from backup will not work. Just plugging in a new drive into the array and waiting for a rebuild does not a guarantee of success. WeRecoverData.com offers a free initial consultation and around-the-clock response. If you find yourself in the unfortunate position of needing a RAID 5 data recovery, contact us for peace of mind and a prompt resolution.  Our highly trained engineers have years of experience specializing in RAID recoveries and utilize state-of-the-art proprietary technology.  If we can’t recover your critical data, it is simply not possible!
