■ RAID 10 Mode (Enables high-speed access and secure storage
of data)
Four hard drives are combined into a large virtual drive. Usable space is the total of two hard drives'
capacity. Because reads are distributed over two drives, access speeds are slightly faster than an
individual drive's. All data is written simultaneously to two hard drives. As a result, if one hard drive from
a pair (either 1-2 or 3-4) fails, all data can be recovered by replacing the drive. However, if two drives
from different pairs fail, such as 1 & 3, or 2 & 4, then data will not be recoverable.
