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.
