The Samsung SSD 850 EVO is based on the technologically advanced 3D V-NAND architecture to achieve maximum read and write speeds in sequential and random access. Its layered cell architecture stacks cells vertically instead of side by side.
This results in higher density and better performance utilising a smaller footprint, breaking through the limitations of conventional planar NAND architecture. Compared to its 840 EVO predecessor, you now get up to 10% greater flexibility for better user experience. Having doubled the cell endurance for writing and minimised performance degradation, the 850 EVO assures long-term dependable performance of up to 30% longer than the previous generation 840 EVO. Samsung has so much confidence in its new SSDs that it now provides a 5 year warranty.
