35
RAID 5
(TS-XL only) - All drives in a RAID 5 array reserve part of their data space for parity
information, allowing all data to be recovered if a single drive fails. The parity information takes
up about one hard drive’s worth of space, so if you set up all four drives in the TeraStation as a
RAID 5 array, your usable capacity will be about 3/4 of the total capacity of the TeraStation. This
is the default configuration for the TS-XL.
RAID 10
(TS-XL only) - Combines RAID 1 and RAID 0 for a fast, secure array. Half of the
TeraStation’s total capacity is used for redundant information.
