Conguring RAID

By default, the TeraStation is congured with Drive C, a mirrored array accross drives 1 and 2, and

Drive D, a RAID 5 array accross drives 1, 2, 3 and 4. Other congurations are available. Changing

Mirrored Volume - Partitions on 2 drives are paired in a mirror array. Identical data is written to

each partition. Usable capacity of the array is the size of whichever partition is smallest. If a drive

malfunctions, data from the volume can be recovered by replacing the failed drive.

Striped Volume - Partitions on 4 drives are combined into one array. Fast write performance makes

this one of the best performing types of volumes. No parity is stored, so if any drive fails, all data

on the volume is lost.

Spanning Volume - Unused partitions from multiple hard drives are combined in one usable volume,

allowing you to make better use of partitions that might not be usable otherwise. If any drive used

the the volume fails, all data on the volume is lost.

Simple Volumes - Drives are addressed separately in Windows. No array is used.
