The Micron RealSSD C400 is a 2.5-inch SATA III solid state drive with 256GB of MLC NAND, sold under part number MTFDDAK256MAM. It was one of the early 6Gb/s SATA drives built on Micron's own flash, and it delivers the fast boot times and quiet, shock-resistant operation that made SSDs a worthwhile upgrade over spinning disks. It suits older laptops and desktops that still have a 2.5-inch SATA bay, or anyone reviving a machine on a budget. Against current SATA drives it is dated: sequential speeds sit well below what modern TLC drives reach, and 256GB fills quickly with games and media.
