| Specifications subject to change without notice. |
| 1 1MB = 1 million bytes, 1GB = 1 billion bytes and 1TB = 1 trillion bytes. Actual user capacity may be less depending |
| on operating environment. |
| 2 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. |
| 3 See support.wdc.com/warranty for regionally specific warranty details. |
| 4 Not all products may be available in all regions of the world. |
| 5 This hard drive product meets or exceeds Restriction of Hazardous Substances (RoHS) compliance requirements |
| as mandated by the RoHS Directive 2011/65/EU and Directive (EU) 2015/863.6 Up to stated speed. As used for transfer rate, 1 MB/s = 1 million bytes per second. Based on internal testing; |
| performance may vary depending upon host device, usage conditions, drive capacity and other factors. |
| 7 Actual spindle motor rotational speed for this model is 7200 RPM; although ID Device may report 5400 to reflect |
| previous Performance Class designation. |
| 8 Controlled unload at ambient condition. |
| 9 MTBF specifications are based on a sample population and are estimated by statistical measurements and |
| acceleration algorithms under typical operating conditions: workload of 90TB/year and drive temperature of |
| 40°C. Derating of MTBF will occur above these parameters, up to 65°C drive temperature. MTBF does not predict |
| an individual drive’s reliability and does not constitute a warranty. Not all products may be available in all regions |
| of the world. |
| 10 Power measurements at room/ambient temperature. |
