1. As used for storage capacity, 1GB = 1 billion bytes and 1TB = one trillion bytes. Actual user capacity may be less depending on operating environment.

2. As used for transfer speed, megabyte per second (MB/s) = one milltion bytes per second. Performance will vary depending on your hardware and software components and configurations.

3. 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.

4. See support.wdc.com/warranty for regional specific warranty details.

5. 5 years or Max Endurance (TBW) limit, whichever occurs first. See support.wdc.com for regional specific warranty details.

6. MTTF = Mean Time To Failure based on internal testing using Telcordia stress part testing (Telcordia SR·332, GB, 25°C). MTTF is based on a sample population and is estimated by statistical measurements and acceleration algorithms. MTTF does not predict an individual drive's reliability and does not constitute a warranty.
