recovery options.

Ultra-cool operation

A cool drive is a more reliable drive.

WD continues to develop new and

innovative ways to keep drives cool

while they are operating.

Quiet

Noise levels have been minimized to

less than one sone* - virtually below

the threshold of human hearing.

Low power consumption

The drive draws less than 2 Watts

while operating and a mere 4.75

Watts during spin up.

1 million hours MTBF

Best-in-class reliability for

small-form factor AV storage.**

Preemptive Wear Leveling

(PWL)

The drive arm frequently sweeps

across the disk to reduce uneven

wear on the drive surface common

to audio video streaming

applications.

* A sone is a subjective unit of loudness as perceived by a

person with normal hearing.

** Based upon dual tuner system operating in typical 30°C air

ambient environment.

1As 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 3 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.
