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 6 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 Controlled unload at ambient condition.
4 Product MTBF and AFR specications are based upon a 40°C base casting and system workloads of up to 180 TB/year (workload is dened as the amount of user data transferred to or from the hard drive).
5 Based on a typical 1-5 bay tabletop NAS product environment under normal operating conditions.
6 The term of the limited warranty may vary by region. Visit http://support.wd.com/warranty for details.
7 No non-recoverable errors during operating tests or after non-operating tests.
8 Sound power level.
