Samsung SSD 850 Pro comes with the technologically innovative 3D V-NAND architecture to achieve the maximum read and write speeds of sequential and random access. This architecture layers cells on the top of each other instead of side by side.
The result is a higher density and higher performance at smaller dimensions, and thus it overcomes the conventional planar NAND architecture. At the same time, if compared to the previous models, it has double the life. V-NAND technology can reliably handle entry of 150 TB (TBW), which is equal to 40 GB per day for 10 years. Samsung trusts this SSD so much that it gives 10-year warranty on it!
