1
2 to 32 disks,
up to 2 TB
Mirroring and duplexing.
Data written to one disk is duplicated to a second for
maximum data protection, but with 50% usable capacity.
If a physical disk fails and a hot spare disk is available, the
controller automatically inserts the spare and builds onto it
the contents of the failed disk
5
up to 2 TB
Independent data disks with distributed parity blocks.
Employs a combination of striping and parity checking. The
use of parity checking provides redundancy without the
overhead of having to double the disk capacity.
If a physical disk fails and a hot spare disk is available, the
controller automatically inserts the spare and builds onto it
the contents of the failed disk from data and parity
information on the remaining disks. For many applications,
RAID 5 offers the best compromise between capacity,
reliability, and speed.
