Crucial announced its M550 series of performance SSDs, succeeding its existing M500 series. Built in 7 mm-thick 2.5-inch SATA, mSATA, and M.2 form-factors, the M550 series offers higher sequential transfer rates, and comes in higher capacities near existing price-points, over its predecessor. It also introduces a handful new features, such as NWA (native write acceleration), RAIN (redundant array of independent NAND), adaptive thermal protection (ATP), and hardware encryption. The drives appear to be based on a Marvell-made controller platform, with Micron-made MLC NAND flash. The mSATA 6 Gb/s and M.2 models come in capacities of 128 GB, 256 GB, and 512 GB; while the 2.5-inch SATA 6 Gb/s models include 1 TB capacity. The drives offer sequential reads as high as 550 MB/s, with up to 500 MB/s of sequential writes. They're backed by 3-year warranties, and should eventually replace the M500 series from their existing price points.
