Actual user storage less. ³ Test Conditions: Performance is based on the CrystalDiskMark 6.0.2 benchmark using a 1000MB LBA range ASUS Z270A desktop with Intel® i7-7700K 3.4GHz, 8GB 2133MHz DDR4. Windows 10 Pro 64-bit 19H1 using Microsoft StorNVMe driver, secondary drive. Performance may vary based on host device. 1 MB = 1,000,000 bytes. IOPS = input/output operations per second. ⁴ TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity. ⁵ Measured using the MobileMark™ 2014 on ASUS B9440UA WITH I5-7200U, 8GB RAM. Windows 10 Pro 64-bit 19H1 using Microsoft StorNVMe driver, Primary drive. 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. ⁷ Operational temperature is measured by an on board temperature sensor. ⁸ Non-operational storage temperature does not guarantee data retention. ⁹ 5 years or Max Endurance (TBW) limit, whichever occurs first.
