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 Striping interleaves data across multiple drives
The disk array’s data capacity is equal to the number of disk drive members
multiplied by the smallest drive's capacity. For example, one 100 GB and three
120 GB drives will form a 400 GB (4 x 100 GB) disk array instead of 460 GB.
If physical drives of different capacities are used, there will also be unused
capacity on the larger drives.
RAID 0 logical drives on VessRAID consist of one or more physical drives.
