1. Backwards compatible to SATA 3 Gb/s and SATA 1.5 Gb/s.

2. 1GB = 1 billion bytes and 1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment.

3. 1MB/s = 1 million bytes per second. Based on internal testing; performance may vary depending upon host device, usage conditions, drive capacity, and other factors.
   IOPS = input/output operations per second.

4. TBW (terabytes written) values calculated using JEDEC Client (2.5” and M.2 2280 models in 500GB and 1TB capacities and M.2 2280 model in 2TB capacity) and Enterprise (2.5” model in 2TB capacity, projected value) workload (JESD219) and mixed sequential and random workload (4TB model) and vary by product capacity.

5. Measured using the MobileMark™ 2012 benchmark with DIPM (Device Initiated Power Management) enabled.

6. MTTF = Mean Time To Failure based on internal testing using Telcordia™ stress part testing (Telcordia SR-332, GF, 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.

7. The SSD box package is rated up to 60°C.

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