RAID recovery

Hard disk RAID arrays are frequently used to store vital information. When they fail it can be a stressful for situation even for the most experienced IT professional. Reconstructing a failed RAID array requires expert knowledge of both system controllers and filesystems. Cheadle Data Recovery Offers recovery or all RAID configurations, including:

Cheadle Data Recovery offer free consultation, free diagnosis, and free turnaround time estimate. It is also possible for Cheadle Data Recovery to send out a technician to your building to examine the RAID array.

About RAID

"RAID" is now used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple hard disk drives. The different schemes/architectures are named by the word RAID followed by a number, as in RAID 0, RAID 1, etc. RAID's various designs involve two key design goals: increase data reliability or increase input/output performance. When multiple physical disks are set up to use RAID technology, they are said to be in a RAID array. This array distributes data across multiple disks, but the array is seen by the computer user and operating system as one single disk. RAID can be set up to serve several different purposes.

Why does RAID fail? RAID systems can fail due to the following reasons:

Below: RAID example - RAID 0

RAID 0 data distribution. Data is spread over two physical hard disk drives. It provides improved performance and additional storage but no redundancy or fault tolerance. A single disk failure destroys the entire array because when data is written to a RAID 0 drive, the data is broken into fragments.

This setup is commonly found in Lacie Big Disk and G-Tech drives.
