Last week Samsung unveiled the world's first 3D vertical NAND memory, and this week it announced the first solid state drives built with that memory. However, these SSDs are intended for the enterprise market and not consumer, at least at first. The V-NAND SSD comes in 480 and 960GB capacities, with the V-NAND's high capacity and outstanding reliability essential for enterprise-class servers. The 960GB model offers a more than 20% boost in sequential read and write speeds compared to non-3D V-NAND models, while still using the SATA 6Gbps interface. Samsung's 3D V-NAND memory uses "cylinder-shaped 3D Charge Trap Flash cell structures and vertical interconnect process technology to link the 24 layers comprising the 3D cell array." It basically allows for manufacturing productivity improvements more than double that of 20nm NAND flash.
Samsung does intend to create V-NAND SSDs for consumers, just right now the focus is on enterprise-class uses. The V-NAND SSDs began production this month, so I imagine it won't be long before data centers, businesses, and more start receiving some.
