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.
