What is RAID?
RAID, short for Redundant Array of Independent Disks, is a combination of two or more disks with the aim of providing fault
tolerance and improving performance. There are several different levels of RAID, with each one providing a different method of
sharing or distributing data among the drives. The ShareCenter Pro supports
JBOD
,
RAID 0
,
RAID 1
,
RAID 5
, and
Standalone
.
RAID 0 provides data striping, which spreads out
blocks of data over all drives, but does not provide
data redundancy.
Although performance is improved, the lack of
fault tolerance means that if one drive fails, all data
in the array will be lost.
RAID 1
RAID 1 provides mirroring over multiple disks, with the
same read/write speed of a single disk. A RAID 1 array can
only be as large as it’s smallest member disk.
Because the data is stored on multiple disks,
RAID 1 provides fault tolerance and protection, in
addition to performance advantages.
