The new 2.5-inch 7 mm SATA drives feature Intel's eight-channel controller (PC29AS21CA0), the company's 20 nm NAND (IMFT, 64 Gb Die), and 1 GB of DDR3-1600 cache. However, the company overclocked the controller by 50 percent, bumping the speed up from 400 MHz to 600 MHz. The company also overclocked the NAND by 20 percent (83 to 100 MHz), resulting in 50µs read latencies. According to the specs, the 240 GB version provides sequential read speeds up to 550 MB/s and sequential write speeds up to 270 MB/s. Random 4 KB read and write are up to 86,000 and 56,000 IOPS, respectively, and the endurance is 50 GB writes per day. This drive, along with the 480 GB version, comes with a five year warranty.
