REBUILD
The RAID MASTER’s Rebuild feature is available manually under RAID 1 and
RAID 1+0. If one of the existing RAID Set becomes “degraded/broken”,
functional hard drive/SSDs can be inserted to Rebuild and recover the data
within the degraded/broken RAID Set. However, recovery of the data/RAID Set
depends on each situation (RAID Mode, number of “non-functional” Disks, etc).
The use of identical hard drive/SSDs from the same manufacturer, having the
same capacity and RPM is highly recommended
.
Please read the "REBUILD: …" section under “RAID MASTER: OPERATION”
for more information.
RAID MODES
A Redundant Array of Independent (or Inexpensive) Disks (RAID) is a system
that utilizes multiple hard drive/SSDs to share or replicate data among the hard
drive/SSDs. The benefit, depending on the selected RAID Mode (combinations
of disks), is one or more of increased data integrity, fault-tolerance, throughput or
capacity as a single drive when compared to individual hard drive/SSDs.
Any RAID mode changes or deletions will erase all the existing data inside the
hard drive/SSD. It is highly recommended
to save all existing data to another
hard drive/SSD before performing any RAID mode changes or deletions.
Using identical hard drive/SSDs with the same capacity and RPM, and from
the same manufacturer are highly recommended
for best performances.
