OWC Mercury Elite-AL Pro Dual mini Chapter 2 - System Setup
2 SYSTEM SETUP
2.2 RAID Conguration (continued)
The OWC Mercury Elite-AL Pro Dual mini is able to utilize the 2 hard drives
in 3 dierent RAID modes; Disk Spanning (SPAN), Disk Striping (RAID-0), or
Disk Mirroring (RAID-1). You need to choose the RAID mode that suits your
needs properly.
Disk Spanning
The drives show up as one large single volume. The total size will depend
on the drives installed, you can use drives of dierent capacities. Spanning
is an array (not RAID) that is written sequentially to, across the hard drives.
By itself, it does not provide any performance or redundancy benets.
Disk Striping (RAID 0)
The drives show up as one large (single) volume. It is highly recommended
to use identical hard drives for this RAID method. However, you can utilize
drives of dierent capacity, but realize that the RAID size will be based on
the smallest capacity total of the drives used in the RAID set.
Disk Mirroring (RAID 1)
The drives show up as one volume, but only 50% of the total capacity can
be used. It is highly recommended to use identical hard drives for this RAID
method. However,while you can utilize drives of dierent capacity, the
RAID size will be based on the smallest capacity total of the drives used
in the RAID set. RAID 1 creates an exact copy (or “mirror”) of a set of data
on the second drive. This is useful when reliability and backup are more
important than capacity. When one drive fails, it can be replaced and the
data rebuilt.
