Data recovery service for RAID 0, 1, 5 systems

RAID data storage is mostly used in enterprise servers. This type of storage has however democratized itself to small external systems such as Network attached storage (NAS). RAID systems are also present in computers where speed of data access is crucial, such as gaming computers.

The three types of RAID commonly used:

Although there are other variants, the most common RAID configurations are RAID 0, RAID 1 and RAID 5.

In addition to RAID configurations, there is also the JBOD which is stacking the capabilities of multiple disks into a logical volume which behaves as it was a single disk.

How to differentiate RAID types and JBOD

Trait : The data is mirrored, that is, replicated between the various data carriers. Data as well as parity check information constitute blocks that are stored in turn on the data carriers involved. Data streams are divided and distributed between data carriers. So each one contains only a fraction of the written data. The way the data is written depends on each system, but in general the data fills the first disk, then the second, and so on.
However, fragmentation of files between multiple disks can occur.

Number of data carriers: ≥ 2 ≥ 3 ≥ 2 ≥ 2
Total storage capacity: C
  • C : capacity of the smallest data carrier
≤ (N-1) * C
  • N : number of data carriers
  • C : capacity of the smallest data carrier
≤ N * C
  • N : number of data carriers
  • C : capacity of the smallest data carrier
C1 + C2 + … + Cn
  • C1 : capacity of the 1st disk
  • C2 : capacity of the 2nd disk
  • Cn : capacity of the nth disk
