 For 1000GB capacity.
 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. As used for transfer rate or interface, megabyte
per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second.
Performance will vary depending on your hardware and software components and configurations.
 Not all products may be available in all regions of the world.
 Backward compatible with PCIe Gen3 x2, PCIe Gen3 x1, PCIe Gen2 x4, PCIe Gen2 x2, and PCIe Gen2 x1.
 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.
 Q=Queue, T=Thread.
 TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity.
 Power measurements at 25°C.
 Measured using MobileMark

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.

Operational temperature as reported by device (composite temperature).

Non-operational storage temperature does not guarantee data retention.
