As used for storage capacity, one gigabyte (GB) = one billion bytes and one terabyte (TB) = one trillion bytes.
Total accessible capacity varies depending on operating environment.
2
Test Conditions: Performance is based on the CrystalDiskMark 5.2.2 benchmark using a 1000MB LBA range ASUS
Z170A desktop with Intel® i7–6700K 4.0GHz, 8GB 2133MHz DDR4. Windows 10 Pro 64-bit 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.
3
TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity.
4
Measured using MobileMark™ 2014 on HP EliteBook X360 1030 G2 with i7–7600U, 8GB RAM. Windows 10 Pro,
64-bit RS3 using Microsoft StorNVMe driver, primary drive.
5
Power measurements at 25°C.

MTTF = Mean Time To Failure based on internal testing using Telcordia stress part testing. 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. (Telecordia SR-332, GB, 40°C)
