Raid Configuration - Buffalo TS-XL User Manual

RAID Configuration

RAID configuration is done in System/Storage.
To change RAID configuration, click on an
array name in the RAID Array under the RAID
Configuration section.
Several types of RAID arrays are available.
RAID 0 - All drives are combined into one large,
fast drive, giving the maximum capacity for
your TeraStation. This size is the one listed
on your TeraStation's box and shows the total
capacity of the TeraStation with no data used
for redundancy. RAID Spanning is fast and
efficient, but with no redundancy, if one hard
drive fails, all data on the TeraStation is lost.
RAID 1
- Hard drives are arranged in mirrored
pairs. Each half of the pair reads and
writes exactly the same data. This costs you half the total capacity of the array, but provides
excellent redundancy. If a hard drive fails, the mirror continues to supply data, so you may work
on normally. You may replace the damaged or defective drive at any time, and normal RAID 1
mirroring will then be automatically restored. This is the default configuration for the TS-WXL/R1.
