RAID Mode Switches M2, M1, M0 (SW1:3 – SW1-5)

the unit is powered up while the RAID Mode button is held down. Each type
of RAID has different properties and requirements, as follows:

1 Audible alarm is recommended at all times.

JBOD Mode (Individual Drives)
Number of drives: at least 1
Unit capacity: N/A (100% of each individual drive)
Spares: no
Fault tolerance: none
JBOD mode offers all connected units to the host adapter, no RAID is defined
at all.
NOTE: JBOD mode requires a SATA controller featuring Port Multiplier
support for eSATA connections.
NOTE: Optical drives can only be configured as JBOD using an eSATA
connection.
RAID 0 (Stripe set)
Number of drives: at least 2
Unit capacity: size of each member times number of members.
Spares: no
Fault tolerance: none - if any member is lost all data is lost.
RAID 0 “stripes” the file system across the array by placing sectors of data
sequentially between drives in a specific order.
