RAID Configuration

RAID 0 (Stripe)

Striping is a performance oriented, non-redundant data mapping

technique. It does not provide fault tolerance. Data is spread across

all disks in the stripe set allowing multiple I/O operations enhancing

performance by taking advantage of today bus mastering technology.

The drawback is when one disk fails the whole group fails. Two to

four blank hard drives are required for striping.

It is recommended to use identical hard drives for all RAID

configurations, however it's also possible to combine hard drives of

different sizes and makes. In a stripe set, when combining hard

drives of different sizes the total stripe size will be the sum of the

smallest hard drive.
