Samsung launches new 2TB SSDs

Samsung has announced a pair of high-capacity SSDs based on its 3D NAND (also known as V-NAND) technology — the 850 EVO and the 850 Pro. Specs on the drives are similar to the smaller capacity products that have already launched, but the drive densities have skyrocketed. The 2TB 850 Pro contains 128 individual 32-layer Flash ICs (128Gb capacity per IC, or 16GB). Samsung also upgraded the MHX NAND controller to handle 2TB arrays, and boosted the on-drive cache to 16Gb (2GB) of LPDDR3. Take the original 850 Pro and 850 Evo and scale them up, and this is what you get.
