1 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 3 Gb/s transfer rate calculated according to the Serial ATA specication published by the SATA-IO organization as of the date of this specication
sheet. Visit www.sata-io.org for details.
2 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.
3 Maximum burst rate running the Mode 5 Ultra ATA transfer mode.
4 Controlled unload at ambient condition.
5 The term of the limited warranty may vary by region. Visit support.wd.com/warranty for details.
6 No non-recoverable errors during operating tests or after non-operating tests.
