2.3RAID 10

RAID 10 is a combination of RAID 1 and RAID 0. RAID 10 has mirrored drives. It breaks up data into smaller blocks, then stripes the blocks of data to each RAID 1 RAID set. Each RAID 1 RAID set then duplicates its data to its other drive. The size of each block is determined by the stripe size parameter, which is set during the creation of the RAID set. RAID 10 can sustain one drive failure in each array while maintaining data integrity.

Uses

Works best for data storage that must have 100% redundancy of

 

RAID 1 (mirrored arrays) and that also needs the enhanced I/O

 

performance of RAID 0 (striped arrays). RAID 10 works well for

 

medium-sized databases or any environment that requires a higher

 

degree of fault tolerance and moderate to medium capacity.

Strong Points

Provides both high data transfer rates and complete data

 

redundancy.

Weak Points

Requires twice as many drives..
