3D NAND

At CES, Samsung displayed a variety of new SSD solutions, including PM863 and SM863, the company's new SATA 6Gbps enterprise drives. At the time Samsung was only sampling its key OEM customers, but with today's announcement Samsung is making the drives available through its retail channel in early August. The PM863 and SM863 are based on Samsung's in-house "Mercury" controller, but unfortunately I don't have any additional details on the controller architecture itself. I'm guessing it's a derivative of the client-grade controllers utilizing ARM Cortex R4, but I'll have to wait for Samsung's reply before I know for sure.
