Backward compatible to SATA II and I.

As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating

environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. 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. Effective maximum SATA 6 Gb/s transfer rate calculated according to the Serial ATA speciﬁcation published by the SATA-IO organization as of the date of this speciﬁcation sheet. Visit

www.sata-io.org for details.

Performance is based on the CrystalDiskMark benchmark using a 1000MB LBA range on ASUS Z170A ATX desktop with Intel Z170 chipset, Intel i7–6700K 4.0GHz, 8M, Skylake, 8GB 2133MHz DDR4, Windows 10 Pro 64-

bit using Intel iRST version 15.2.0.1020, secondary drive, C-state off. Performance may vary based on host device. 1 MB = 1,000,000 bytes. IOPS = input/output operations per second.

Measured using the MobileMark™ 2014 benchmark with DIPM (Device Initiated Power Management) enabled.

MTTF = Mean Time To Failure based on internal testing using Telcordia stress part testing.
