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.
