SouthBit Data Recovery specialises in recovery from all types of RAID arrays. RAID setups are prevalent in servers, NAS devices, external drives and other instances where a large amount of storage is required, along with some form of redundancy.
SouthBit currently has a 100% recovery rate for all RAID failures sent in for recovery. From small, 2 drive setups to 16 drive rack mounted servers, we offer the best chance of recovering your failed RAID array.
The most common types of RAID configurations are as follows:
Known as a striped set or striped volume. Data is written evenly across multiple disks, without parity. Speed and performance are the advantages of RAID 0. However, RAID 0 provides no redundancy. If one drive in the array fails, the entire array goes down. RAID 0 is also used to create a large volume out of smaller disks. This configuration is often used where performance is key and data security is not a requirement.
Known as a mirrored set. This type of configuration mirrors data across 2 disks. This setup has good redundancy as there are essentially 2 copies of the data on 2 physical disks. The RAID volume can only be as big as the smallest disk. RAID 1 has many advantages, but does not make good use of available disk space.
This configuration uses block-level striping with the parity data spread across all disks. It requires a minimum of 3 disks. RAID 5 makes good use of available disk space and offers redundancy with performance. One of the most popular RAID configurations. They can be managed by either hardware of software controllers.
RAID 10 (0+1)
This uses the advantages of RAID 0 (speed via striping) and RAID 1 (mirror) to give a configuration that provides both speed and redundancy. Disk usage is, however, not ideal.RAID illustrations curtosey of http://www.prepressure.com
