Network Storage System

with RAID

Small-footprint, 4-bay System

Gigabit Ethernet

RAID 0/1/5

Ideal for small ofﬁces and

home networks with 3 to 10

networked computers who

want centralized storage.

Centralized storage

with plenty of capacity

to go around.

This high-speed network-attached storage system with capacities

up to 8 TB and a space-saving footprint gives you all the

beneﬁts of a big time data center without the need for a big

time IT department. Perfect for centralizing and sharing data and

multimedia ﬁles on a small ofﬁce or home network.

Big capacity, small footprint — Offered in 2, 4 and 8 TB

capacities, this small-footprint four-bay system takes up very little

space and provides plenty of storage to go around.

High-speed access, Ethernet connectivity — Provides data

transfer rates up to 1,000 Mb/s when used in a GigE network.

Gigabit networking and transfer rates are ﬁve to six times

faster than other network storage systems. This performance is

comparable to USB 2.0 direct-attached storage.

RAID capability — Offers multiple RAID conﬁgurations for data

protection and speed – RAID 0 (Striped), RAID 1 (Mirrored),

and RAID 5. The RAID 5 mode, only available on the fully-

populated 4-drive system, is the recommended mode to achieve

both high-performance and data protection through redundancy.

Remote access software — Access your ﬁles anywhere,

anytime using MioNet

remote access services from WD.

Stream digital media anywhere in your home — Built-

in DLNA certiﬁed media server for streaming music, photos

and movies to any DLNA certiﬁed multimedia device such as

As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total

accessible capacity varies depending on operating environment. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second,

and gigabit per second (Gb/s) = one billion bits per second. Total accessible capacity varies depending on operating environment and RAID conﬁguration. RAID 0

(striped) accesses the full capacity of the drives. RAID 5 accesses three-fourths of the total capacity for data protection. RAID 1 (mirrored) accesses half of the total

capacity for additional data protection. 4178-705023-A03 Jan 2009
