Specifications subject to change without notice.
1 Backward compatible to SATA II and I.
2 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.
3 Performance is based on the CrystalDiskMark benchmark using a 1000MB LBA range on Gigabyte GA-Z77X-UD5H desktop with Intel Z77 chipset, Intel i7-3770 3.4GHz, 8M, Ivy Bridge, Windows 8 64-bit SP1 using Intel iRST version 18.104.22.1683, secondary drive, C-state off. Performance may vary based on host device. 1 MB = 1,000,000 bytes. IOPS = input/output operations per second.
4 TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity.
5 Measured using the MobileMark™ 2012 benchmark with DIPM (Device Initiated Power Management) enabled.
6 MTTF = Mean Time To Failure based on internal testing using Telcordia stress part testing.
