OWC Mercury Rack Pro mini-SAS
Chapter 1 - Introduction
1.6.4 Disk Mirroring with Striping (RAID 10) (also known as RAID 1+0)
The drives show up as one volume, but only 50% of the total capacity can be used,
depending on the drive with the smallest capacity. RAID 10 creates an exact copy (or
“mirror”) of a set of data but also uses a RAID 0 Stripe for speed. When one hard drive
fails, it can be replaced and the data rebuilt automatically.
1.6.5 Disk Striping with dedicated parity (RAID 3)
The drives show up as one volume, but the total capacity, depending on the drive with
the smallest capacity, is the combined size minus the size of one drive. RAID 3 uses
byte level striping with parity data located on 1 disk. Very fast performance can be
achieved with RAID 3.
1.6.6 Disk Striping with distributed parity (RAID 5)
The drives show up as one volume, but the total capacity, depending on the drive with
the smallest capacity, is the combined size minus the size of one drive. RAID 5 uses
block level striping with parity data distributed across all member disks and therefore
provides the perfect balance between high performance and data integrity. When one
hard drive fails, it can be replaced and the data rebuilt automatically.
1.6.7 Clear RAID Mode (also known as Independent)
Each drive will appear as a single volume. If you wish to use a mixed variety of capacity
and model hard drives, this is the mode to use.
NOTE:
Hard drives of identical model are required for all RAID types.
