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.
WD hard drive products manufactured and sold worldwide after June 8, 2011, meet or exceed Restriction of
Hazardous Substances (RoHS) compliance requirements as mandated by the RoHS Directive 2011/65/EU.
Controlled unload at ambient condition.
MTBF specifications are based upon internal testing using a 40°C base casting temperature. MTBF is based on
a sample population and is estimated by statistical measurements and acceleration algorithms. MTBF does not
predict an individual drive’s reliability and does not constitute a warranty.
Workload Rate is defined as the amount of user data transferred to or from the hard drive. Workload Rate is
annualized (TB transferred X (8760 / recorded power-on hours)). Workload Rate will vary depending on your
hardware and software components and configurations.
See http://support.wd.com/warranty for regionally specific warranty details.
Power measurements at room-ambient temperature.
No non-recoverable errors during operating tests or after non-operating tests.
