Detail — Click “Detail” to see additional disk information. If the drive supports

In this section (Model 505895 only), you can manage the RAID array and set up
your drives. The Gigabit SATA NAS supports RAID 0 and RAID 1. Two hard drives
of identical capacity and make are required. If only one drive is installed, the RAID
conguration will not be available.
RAID 0 — Used when speed is the primary objective, RAID Level 0 (also called
“striping”) is not redundant. This form of array splits each piece of data across
both of the drives in segments; since data is written without any form of parity
data-checking, it allows for the fastest data transfer compared to the other
setups. However, if one drive becomes damaged, the whole array can become
corrupted.
RAID 1 — This mode requires two identical drives for implementation. A RAID 1
creates an exact copy (or mirror) of a set of data on the second drive, useful
when reliability and backup are more important than data capacity. Available
capacity to the user will only be as large as a single drive, but when one of the
