RAID 0 – Stripe
When a RAID Volume is striped, the read and write blocks of data are interleaved
between the sectors of multiple disk drives. Performance is increased, since the
workload is balanced between drives or “members” that form the RAID Volume.
Identical drives are recommended for performance as well as data storage
efficiency.
Figure 1. RAID 0 Striping interleaves data across multiple drives
The RAID Volume’s data capacity equals the capacity of the smallest disk drive
times the number of disk drives. For example, one 100 GB and three 120 GB
drives will form a 400 GB (4 x 100 GB) RAID Volume instead of 460 GB.
If disk drives of different capacities are used, there will also be unused capacity
on the larger drives.
Because RAID 0 does not offer Fault Tolerance, meaning that you cannot recover
your data after a disk drive failure, Promise does not recommend a RAID 0
Volume for your SmartStor.
RAID 0 Volumes on SmartStor consist of one or more disk drives.
