RAID (Redundant Array of Independent Disks) is a special data storage configuration in which at least two interconnected hard drives work together to provide additional storage space, offer an additional layer of protection against data loss, and/or increase read/write speeds. Despite the complexity of RAID and the difficulties in reassembling a failed configuration, ASAP Data Recovery Services provides RAID data recovery services affordable enough for both businesses and individuals. Our engineers have spent more than a decade overcoming the most difficult of problems to recover data from failed RAID configurations and have gained considerable experience throughout. We pledge that if we can’t recover the data from your malfunctioning RAID configuration, nobody can!
Two of the three beneficial characteristics of RAID configurations, an additional layer of protection against data loss and an increase in read/write speeds, are achieved through “striping,” “mirroring,” and “parity.” “Striping” is the process of spreading data across multiple hard drives so that each hard drive could access its respective portion in unison, which allows for faster read/write speeds. “Mirroring” occurs when two or more drives contain identical data, which offers protection against data loss in the event that one or more of the drives within the configuration fail. “Parity” is when a portion of each drive within the configuration (or, in some cases, an entire drive) is appropriated for recovering data lost when a drive within the configuration fails. Additional storage space, the third beneficial characteristic of RAID configurations, is only achieved in RAID 0, where data is split evenly across two or more drives.
| RAID Level | Striping | Mirroring | Parity |
| RAID 0 | X | ||
| RAID 1 | X | ||
| RAID 2 (Obsolete) | X | X (Dedicated*) | |
| RAID 3 (Obsolete) | X | X (Dedicated*) | |
| RAID 4 (Uncommon) | X | X (Dedicated*) | |
| RAID 5 | X | X | |
| RAID 6 | X | X (Double Parity**) |
* – Uses a dedicated drive(s) for parity.
** – Offers protection against two drive failures rather than one.
There also exist “hybrid” RAID configurations, which combine the benefits of RAID 0 (additional storage space) and/or RAID 1 (mirroring) with other RAID levels to achieve a higher level of robustness or functionality. Some examples of “hybrid” RAID configurations are RAID 10 (1+0), RAID 100 (1+0+0), RAID 50 (5+0), RAID 51 (5+1), and RAID 60 (6+0).
