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.
