Promise Array Management
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 100 GB and three 120 GB drives will form a 400 GB (4 x 100 GB) disk array.
Stripe Size – A value can be set from 16KB to 256KB sector size. The size can directly affect performance. In the PAM, the default is 64KB.
