Mediasonic HFR2-SU3S2 Pro
Raid Box is a 4 Bay Enclosure for 3.5 SATA I / II hard disk drive. The main
feature of Pro Raid Box is its Hardware Embeded Raid function. It supports RAID
0 / 1 / 3 / 5 / 10
Spanning concatenates multiple
hard drives as a single large volume; resulting in a seamless expansion of
virtual volumes beyond the physical limitations of singularly connected
Striping is a method of concatenating
multiple hard drives into one logical storage unit. It is the automated
process of writing data across multiple drives simultaneously. Striping is
used to increase the performance of disk reads. The multiple hard drives
will write data in “column” effect. If one drive in a striped set fails,
all of the data in the stripe set is lost.
Mirroring is the automated process of writing data
to multiple drives simultaneously. Mirroring is used to provide
If one drive fails, the redundant drive(s) will continue to store the data
and provide access to it. The failed drive can then be
replaced and the drive set
can be re-mirrored.
Striped set with
This mechanism provides an improved performance and
fault tolerance similar to RAID 5 but with a dedicated parity disk rather
than rotated parity stripes. The single parity disk is a bottle-neck for
writing since every write requires updating the parity data. One minor
benefit is the dedicated parity disk allows the parity drive to fail and
operation will continue without parity or performance penalty.
RAID O - Spanning ModeStriped set with
Distributed parity requires all drives but one to be
present to operate; drive failure requires replacement, but the array is
not destroyed by a single drive failure. Upon drive failure, any
subsequent reads can be calculated from the distributed parity such that
the drive failure is masked from the end user. The array will have data
loss in the event of a second drive failure and is vulnerable until the
data that was on the failed drive
is rebuilt onto a replacement drive.
RAID 1 + 0
RAID 1+0 is mirrored(Raid 1) sets in a striped(Raid 0) set .
1. POWER SYNC
Powers off in synchronizatim with PC.
2. FORCED CONVECTION PROCESS
Known for it's exceptional properties for being lightweight, high
rigidity and superior heat dissipation capabilities, Aluminum is an
obvious choice when it comes to constructing a quality hard drive
enclosure, especially with the excess heat generated from the high-speed
hard drives available in the market.
3. SMART FAN
Comes with auto / manual modes & 3 levels of
speed for best convention.
4. Smart Fan functions:

5. HDD X 4 (Supported)
All 4 HDDs are recognized when they are install
