    Chapter 4 Storage Management Chapter 4 Storage Management RAID Modes TeraStations support many types of RAID. The type of RAID arrays available for use depends on how many drives are installed in your TeraStation. Notes: • If you change the RAID mode, all data on the array is deleted. This is true for every procedure in this chapter. Always back up any important data before performing actions that affect your RAID array.

  • Page 43: Working With Raid Arrays

    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.
