What does Raid 5 recovery mean?

The term Raid 5 recovery is used to denote the Raid recovery process for a Raid 5 array in case of data inaccessibility and faulty disk drives. As RAID 5 is most commonly used where large volume of business-critical data are handled successful RAID 5 recovery is extremely important for such organizations.

Characteristic features of Raid 5 array

A Raid 5 array is the most powerful type of Raid array that can be found in network and computing systems, thus making the Raid 5 array to be immensely popular with its users.

A minimum of three disk drives and a maximum of sixteen disk drives are used in Raid 5 array. It is better to use identical disks to ensure a better performance.

Raid 5 array uses the method of striping with parity for redundancy data. In the parity method, two blocks of data are analyzed and a third data block is formed based on the results of the other two data blocks. This process follows the method of binary math.

This parity method allows for data reconstruction when a drive is replaced following Raid failure in any drive. Raid arrays operating twenty four hours a day implement the hot swap technology. This technology allows a faulty drive to be replaced even when the array is running. Through this technology, data can be rebuild even when the array is continuing with its daily operations. However the performance of Raid 5 array degrades during raid rebuild.

Raid 5 array failure

Failure in Raid 5 array can be caused due to a number of problems

  • Server crash in case of server based Raids
  • Inability of the controller card to recognize the disk drives (in case of controller card-based Raids)
  • Corrupt disk drives
  • User unable to access data
  • Data is lost and
  • Replaced drive is attached in a wrong way

Several data recovery companies specialize in the process of Raid recovery. Therefore, whenever a trouble of Raid failure arise, it is always advisable to give a call to these companies indulging in data recovery and Raid recovery.

Data recovery in Raid

The complex process of recovering the data that are either lost or are inaccessible is made easy with the use of specialized, sophisticated software meant for data recovery.

These data recovery software can easily trace back the lost data using the parity information and with the help of sophisticated technologies.

It is advisable to leave the daunting task of Raid recovery to the industry professionals who respond quickly to your calls and offer you user friendly services and that too at attractive packages. Websites of such companies can be easily found in the net.

Raid rebuild in raid 5 recovery takes almost six to eight hours. But the sooner you contact with these raid recovery companies the better are the chances of getting your Raid 5 fixed in time.
