Chapter 3 Managing Storage
Creating Volumes
Notes:
• To create a RAID volume, use RAID Builder instead of the Disk Management option in Windows Storage Server.
• When volumes are deleted or formatted, or the RAID mode is changed, all data stored on the volumes is erased.
Before executing these operations, back up any important data.
• In this manual, "recover" means reverting the TeraStation (including the data) to its former state prior to the drive
failure. It doesn't refer to reading data from a failed hard drive.
Volume Types
RAID 6 Volumes
RAID 6 distributes two parity blocks when writing data. The usable space is equal to the sum of the capacity of four
drives. If two drives in a RAID 6 array fail, data on the array can be recovered after the failed drives are replaced.
However, if three or more drives fail, all data is lost.
RAID 5 Volumes
RAID 5 distributes a parity block when writing data. The usable space is equal to the sum of the capacity of five
drives. If one drive in a RAID 5 array fails, data on the array can be recovered after the failed drive is replaced.
However, if two or more drives fail, all data is lost.
RAID 10 Volumes
Mirrored pairs of drives in RAID 1 arrays are combined into a RAID 0 array. The usable space is equal to the capacity
of three drives. The same data is written to multiple drives so that if one drive from either or both RAID 1 array fails,
data on the array can be recovered after the failed drives are replaced. However, if two drives on the same RAID 1
array or three drives in total fail, all data is lost.
Striped Volumes
RAID 0 stripes data across the multiple drives, but lacks parity blocks like RAID 5 or RAID 6. The usable space is equal
to the capacity of all drives on the TeraStation. RAID 0 doesn't have any redundancy so data cannot be recovered if
even a single drive fails.
Creating a RAID Volumes
