Working With Raid Arrays; Using Jbod - Buffalo TeraStation 1000 User Manual

RAID 1
Combines 2 or more drives into a mirrored array. The available space in the array is the capacity of a single drive.
Identical data is written to each drive. If a drive is 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 2 or more drives into a single array. The usable drive space is the total space of all drives used. This simple
RAID mode offers faster performance than RAID modes that include parity. If a single drive in the array fails, then all
data in the array is lost.
JBOD
This mode uses the hard drives inside the TeraStation as individual drives. The drive space you can use is the total
capacity of all drives in the TeraStation. If any drive is damaged, then the data on that drive is lost.
