Specifications
Footnotes:
Specifications subject to change without notice.
1
Backwards compatible with PCIe Gen3 x2, PCIe Gen2 x4, PCIe Gen2 x2, and PCIe Gen2 x1.
2
1GB = 1 billion bytes and 1TB = 1 trillion bytes. Actual user capacity may be less depending on operating environment.
3
Test Conditions: Performance is based on the CrystalDiskMark 7.0.0f benchmark using a 1000MB LBA range ASUS Z170A desktop with Intel® i7–6700K 4.0Ghz, 8GB 2133MHz DDR4. Windows 10 Pro 64-bit version 1903 using Microsoft
StorNVMe driver, secondary drive. 1 MB/s = 1 million bytes per second. IOPS = input/output operations per second. Based on internal testing; performance may vary depending upon host device, usage conditions, drive capacity, and
other factors.
4
TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity.
5
Measured using MobileMark™ 2018 on Dell Precision 7730 intel® Core™ i5–8300 CPU @ 2.30GHZ 8GB Windows 10 RS5 (1809) Bios 1.13.1
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 thermal sensors in NAND package. The SSD box package is rated up to 60ºC.
8
Non-operational storage temperature does not guarantee data retention.
9
5 years or Max Endurance (TBW) limit, whichever occurs first. See support.wdc.com/warranty for regional specific warranty details.
