 Backwards compatible to SATA 3 Gb/s and SATA 1.5 Gb/s.
 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.
 Measured using CrystalDiskMark, 1000MB LBA range, on Desktop with Intel Z77 chipset,
Windows 8 with Intel iRST version 11.7.0.1013, secondary driveLenovo X240 with Intel®
Core i5–4300U, 4GB RAM, Windows 8.1 update1 x64, Intel RST 12.8.10.1005. Performance
may vary based on host device. 1 MB = 1,000,000 bytes. IOPS = input/output operations
per second.
 TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary
by product capacity.
 Measured using the MobileMark™ 2012 benchmark with DIPM (Device Initiated Power
Management) enabled.
 MTTF = Mean Time To Failure based on internal testing using Telcordia stress part testing.
