RAID
Redundant array of independent disks (RAID) combines multiple physical disks into a single storage unit,
and then distributes data across the disks in one of several predefined methods.
The following features make RAID ideal for use with data storage and NAS applications.
RAID Feature Description Advantages Disadvantages
Grouping Disks that are combined
using RAID form a
RAID group, which QTS
considers one large
logical disk.
Managing the storage space
of one large disk is simpler
and more efficient than multiple
small disks.
Initial configuration can be
more complicated.
