SSD The Samsung 850 EVO is based on a technologically advanced V-NAND 3D architecture to achieve maximum read and write speeds in both sequential and random access. This architecture layers the cells to themselves instead of to each other.
The result is higher density and higher performance in smaller dimensions, thus overcoming conventional NAND flatbed architecture. Compared to the 840 EVO predecessor, you get up to 10% more flexibility for a better user experience. The U 850 EVO has doubled the reliability of the write cells and minimized subsequent downtime performance, making it up to 30% higher than the 840 EVO. Samsung is so strong behind its SSD that it gives it a 5-year warranty!
