NAS compatibility –- WD Network drives are specifically engineered for NAS systems with up to five drive bays.
The drives are designed and extensively tested for compatibility in the unique 24x7 operating environment and
demanding system requirements of home and small business NAS.
Energy efficient – Reduce your electricity bill and carbon footprint with WD Network drives. Innovative
technology reduces power consumption and lowers the operating temperature, resulting in a more reliable and
affordable solution for always on 24x7 NAS environments.
Exclusive NASWare™ technology – The secret is in the technology. Advanced firmware technology built into
every WD Network hard drive, enables seamless integration, robust data protection and optimal performance for
systems operating in NAS and RAID environments.

improvement over standard desktop drives, the WD Network drives are designed and manufactured to be a more
reliable and robust solution for your NAS system.
3D Active Balance Plus – Our enhanced dual-plane balance control technology significantly improves the
overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive
vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over
time.

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 buffer or cache, one megabyte (MB) = 1,048,576 bytes. 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. Effective maximum SATA 6 Gb/s
transfer rate calculated according to the Serial ATA specification published by the SATA-IO
organization as of the date of this specification sheet. Visit www.sata-io.org for details.
