Samsung's 850 Pro offers business-class features, like a 300 TBW (terabytes written) guarantee and ten-year warranty. The drive also supports additional encryption algorithms for drive protection.
VNAND is only featured on the 850 Pro. Vertical NAND can be thought of in a vaguely similar fashion to Intel's 3D transistors – by stacking the cells in three-dimensional space, the drives can fit more data without significantly reducing speed. More on that in our previous article.
Of today's announcement, Samsung stated:
“The new 2TB 850 SSD PRO and EVO drives remain in the same 7-millimeter, 2.5-inch aluminum case as their predecessors did. Equipped with Samsung’s advanced chip solutions, including 128 individual Samsung 32-layer 128Gb 3D V-NAND flash chips, an upgraded high-performance MHX controller that supports 2TB capacity, and four 20nm-class process technology-based 4Gb LPDDR3 DRAM chips, the 2TB 850 family provides industry-leading performance and power efficiency. With added capacity, professionals and consumers can experience a smoother computing environment prepared for the intense demands of rich content such as 4K UHD video editing and viewing.
Following the launch of the 2TB 850 drives, Samsung will expand high capacity 3D V-NAND SSD lineups to include mSATA and M.2 form factors to address the gaming PC, laptop PC and high performance SSD markets.”
