RAID configuration
0

0

(block-level striping without parity or mirroring) has no (or zero) redundancy. It provides improved performance and additional storage but no fault tolerance.

1

(mirroring without parity or striping), data are written identically to two drives, thereby producing a "mirrored set"; the read request is serviced by either of the two drives containing the requested data, whichever one involves least seek time plus rotational latency.

i

5

(block-level striping with distributed parity) distributes parity along with the data and requires all drives but one to be present to operate; the array is not destroyed by a single drive failure.

A RAID-60 composite consists of a RAID-0 array that combines several RAID 6. This requires at least two controllers with four hard disks each, i.e. a total of eight hard disks. In principle, the differences between RAID 5 and RAID 6 are highly scaled to the differences between RAID 50 and RAID 60: throughput is lower, while data security is higher. The simultaneous failure of any two drives is possible at any time without data loss; further failures are only uncritical if a maximum of two drives per striped RAID 6 are affected.

10

A RAID 10 group is a RAID 0 over several RAID 1, combining the characteristics of both RAIDs: security and increased read/write speed.
A RAID 10 network requires at least four hard disks.

50

A RAID 50 array consists of a RAID 0 array consisting of several striped RAID 5.
A RAID-50 network requires at least six hard disks, for example two RAID-5 controllers each with three disks per controller connected together with a software stripe RAID 0.
A RAID-50 network is used in databases where write throughput and redundancy are paramount.

SAS

Serial Attached SCSI (SAS) is a data transfer technology designed to move data to and from computer storage devices such as hard drives and tape drives. It is a point-to-point serial protocol that replaces the parallel SCSI bus technology that first appeared in the mid 1980s in corporate data centers, and uses the standard SCSI command set.
