Dual-level RAID

achieves a balance between the increased data availability

inherent in RAID 1 and RAID 5 and the increased read performance inherent in

disk striping (RAID 0). These arrays are sometimes referred to as

RAID 0+1

or

RAID 10 and RAID 0+5 or RAID 50.

In summary:

•

RAID 0 is the fastest and most efficient array type but offers no fault-

tolerance. RAID 0 requires a minimum of two drives.

•

RAID 1 is the best choice for performance-critical, fault-tolerant

environments. RAID 1 is the only choice for fault-tolerance if no more than
two drives are used.

•

RAID 3 can be used to speed up data transfer and provide fault-tolerance in

single-user environments that access long sequential records. However,

RAID 3 does not allow overlapping of multiple I/O operations and requires

synchronized-spindle drives to avoid performance degradation with short

records. RAID 5 with a small stripe size offers similar performance.

•

RAID 5 combines efficient, fault-tolerant data storage with good performance

characteristics. However, write performance and performance during
drive failure is slower than with RAID 1. Rebuild operations also require
more time than with RAID 1 because parity information is also
reconstructed. At least three drives are required for RAID 5 arrays.

•

RAID 6 is essentially an extension of RAID level 5 which allows for

additional  fault  tolerance  by  using  a  second  independent  distributed
parity scheme (two-dimensional parity). Data is striped on a block level
across a  set  of  drives,  just  like  in  RAID 5,  and  a  second  set  of  parity
is  calculated  and  written  across  all  the  drives;  RAID 6  provides  for  an
extremely  high  data  fault  tolerance  and  can  sustain  multiple
simultaneous  drive  failures.  The  perfect  solution  for  mission  critical
applications.
