7.1 Introduction to RAID
RAID (Redundant Array of Independent Disks) allows multiple disk drives to
be combined together into a RAID Volume. You create a RAID Volume on
your NAS-7400 when you perform the setup procedure, either in the NAS
Setup Wizard or the PASM Setup Wizard.
The benefits of a RAID can include:

Higher data transfer rates for increased server performance

Increased overall storage capacity for a single Volume

Data redundancy/fault tolerance for ensuring continuous system
operation in the event of a disk drive failure
Different RAID levels use different organizational models and have varying
benefits.
7.1.1 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.
