About RAID Arrays
RAID 1 Mirroring
When ConnectStor II is first started, if two disk drives are installed, ConnectStor II
automatically creates a RAID 1 or Mirrored array. RAID 1 maintains identical data on
both drives. If one drive should fail, ConnectStor II will continue responding to data
requests from users. Data will not be lost. When a replacement drive is installed in place
of the failed drive, ConnectStor II automatically sends all data from the original working
drive to the replacement drive until the data on both drives matches each other.
RAID 0 Striping
When ConnectStor II is first started, if one disk drive is installed, ConnectStor II
automatically creates a RAID 0 or Striped array. With ConnectStor II, RAID 0 is used for
one or two drives. Their combined storage capacity appears as a single storage volume (or
drive).
Under RAID 0 with two drives, when a file is saved, ConnectStor II splits up blocks of
data and simultaneously sends different portions to both installed drives. When a file is
read or retrieved, ConnectStor II simultaneously accesses both drives to rebuild the split-
up data. Using RAID 0 striping actually doubles the speed of sustained data transfers
(reads and writes) since two drives perform the work of one drive.
WARNING
: There is no fault tolerance under RAID 0 striping. If
one drive should fail, all data from both drives will be lost. If
you are using RAID 0, backup your critical files elsewhere on
the network.
