1 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.

2 As of April 2017.

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

4 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 environ-

ment. 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.

5 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.

6 Controlled unload at ambient condition.

7 Product MTBF and AFR specifications are based upon a 40°C base casting temperature and typical system workload rate of 219TB/year. Product is designed for workload rates up to 550TB/year.

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

9 No non-recoverable errors during operating tests or after non-operating tests.

10 Sound power level.
