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.
Figure 1. RAID 0 Stripe interleaves data across multiple drives
The logical drive's data capacity equals the capacity of the smallest physical drive
times the number of physical 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.
If physical drives of different capacities are used, there will also be unused
capacity on the larger drives.
A RAID 0 logical drive requires one or more physical drives.
