Working With Raid Arrays; Using Jbod - Buffalo TeraStation 3010 User Manual

Chapter 4 Storage Management
RAID 1
Combines two or more drives into a mirrored array. The usable space is equal to the capacity of a single drive.
Identical data is written to each drive. If a drive becomes damaged, data can be recovered by replacing the
damaged drive. As long as one drive in the array remains undamaged, all data in the array can be recovered.
RAID 0
Combines two or more drives into a single array. The usable space is equal to the total capacity of all drives in the
array. This simple RAID mode offers faster performance than RAID modes that include parity. If a single drive in the
array becomes damaged, then all data in the array will be lost.
JBOD
This mode uses the drives inside the TeraStation as individual drives. The usable space is equal to the total capacity
of all drives on the TeraStation. If any of the drives become damaged, then all data on that drive will be lost.

Working with RAID Arrays
