DATA SHEET

PC HARD DRIVES

WD Blue™

¹ As used for storage capacity, 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.

² Not all products may be available in all regions of the world.

³ 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.

⁴ Controlled unload at ambient condition.

⁵ See http://support.wd.com/warranty for regional specific

warranty details.

Power measurements at room-ambient temperature.

⁶ No non-recoverable errors during operating tests or after

non-operating tests.
