About RAID Levels

Striping (RAID 0)

Reads and writes sectors of data interleaved between multiple drives. When any disk

member fails, it affects the entire array. Performance is better than a single drive since the

workload is balanced between the array members. This array type is for high performance

systems. Identical drives are recommended for performance as well as data storage

efficiency. The disk array data capacity is equal to the number of drive members times the

smallest member capacity. For example, one 1GB and three 1.2GB drives will form a 4GB (4

x 1GB) disk array.

Stripe Size - a value can be set from 1KB to 1024KB sector size. The size can directly affect

performance. In the FastBuild BIOS, the “Desktop” default is 8KB while “Server” and “A/V

Editing” are 64KB.
