Raid Arrays - Buffalo LinkStation User Manual

Using your LinkStation

RAID Arrays

Several RAID modes are available for LS-WXL and LS-WSXL LinkStations. LinkStations with only one
hard drive do not support RAID modes.
Note:– All data is lost when the RAID mode is changed. Back up any important data before
changing RAID modes.
– In this document, "Recovery" means putting the LinkStation back to the state it was in
before the malfunction happened. It does not mean reading data from broken hard
drives.
– When the use mode of the hard disk is changed, all the data in the hard disk gets delet-
ed. Please take back-up before changing use mode so that the important data will not
be lost.
• RAID 1 mode
Uses 2 hard drives in a mirrored array. One drive's worth of space is usable. Identical data is written to
both drives. If one drive is damaged, data can be recovered by replacing the damaged drive.
• RAID 0 mode(LS-WXL, LS-WSXL Default Settings)
Multiple hard drives are combined into a single array. The total capacity of all drives is usable. This is
the fastest of the LinkStation's RAID modes. If any drive is damaged, all data on the array is lost.
• Normal Mode
Each drive is accessible as a separate, individual drive. The total capacity of each drive is usable.
If any drive is damaged, all data on that drive is lost.
