Raid 0 - Stripe - Promise Technology FastTrak TX4650 User Manual

FastTrak TX4650, TX2650 User Manual
RAID 0 – Stripe
When a logical drive is striped, the read and write blocks of data are interleaved
between the sectors of multiple physical drives. Performance is increased, since
the workload is balanced between drives or "members" that form the logical drive.
Identical drives are recommended for performance as well as data storage
efficiency. The logical drive's data capacity is equal to the number of drive
members multiplied by the smallest logical drive member's capacity.
Figure 1. RAID 0 Stripe interleaves data across multiple drives
For example, one 100 GB and three 120 GB drives will form a 400 GB (4 x
100 GB) logical drive instead of 460 GB.
RAID 0 logical drives on the FastTrak TX Series RAID consist of one or more
physical drives.
