USB3.0/eSATA/1394b-to-SATA II RAID Subsystem
10
Quick Setup Guide
Failure in a hard disk will cause the RAID controller to enter into degraded mode. The
host controller can still read/write data to the RAID without knowing any hard disk defect.
Users have to replace the hard disk then the RAID controller will enter in on-line rebuild
mode automatically.
Besides, if there is only partial defect in a hard disk, the RAID controller will read data
from the other healthy hard drive.
Mirror (RAID 10) for High
Performance and High Security
RAID subsystem could be configured to
support Stripe and Mirror at the same
time, i.e. RAID 10. Take four hard
drives in RAID 10 as an example. Hard
drive 0 and hard drive 1 could act as
Mirror 1. Hard drive 2 and hard drive 3
act as Mirror 1 too. The RAID controller
then configures these two Mirrors as
Stripe.
At least two drives (either one in each
Mirror) can be allowed to fail without
any impact to RAID data access. If two
drives from the same Mirror are failed,
the RAID data is not accessible and
becomes invalid.
Concatenating (Large)
This mode is also named “Large”. In this mode,
the RAID controller will concatenate all of the hard
drives into a single hard drive with larger capacity.
For example, if three 500GB hard disks are
connected to the RAID subsystem in Large Mode,
user will get a single hard disk with capacity of
1,500GB.
If any one hard disk gets defective, information
stored in this LARGE RAID will become invalid.
