Samsung has quietly begun shipping a new range of solid-state drives featuring the company's latest 30nm multi-level cell (MLC) NAND flash memory and a multi-core controller chip built in-house. The 470 series just became available in the U.S. Other than that they all share the same features, including a 2.5-inch brushed aluminum casing with orange accents, a SATA 3Gbps interface, TRIM support, a MTBF (mean time before failure) of 1.5 million hours, resistance to shocks of up to 1500G, and a three-year warranty.
