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 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. 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. |
