Samsung 850 Evo SSD 500GB SATA3 Hard Drive

The Samsung 850 Evo SSD 500GB SATA3 2.5-inch 6 Gbps 32-layer SATA (MZ75E500B/EU) hard drive is built under Samsungs' unique and innovative 3D VNAND flash memory architecture, a breakthrough in overcoming the limitations of density, performance and resilience of today's conventional NAND architecture. 

3D VNAND is manufactured by stacking 32 layers of cells vertically on top of each other instead of reducing cell dimensions and trying to fit into a fixed horizontal space, resulting in higher density and better performance using a smaller footprint. The Samsung 850 Evo SSD 500GB SATA3 hard disk drive offers optimized performance for everyday computing experiences. With performance enhanced by TurboWrite technology, the 850 EVO not only provides a 10% better user experience than the 840 EVO, but also random write speeds up to 1.9 times faster for 120/250GB models. 

In fact, the 850 EVO offers first-class sequential reading (540 MB/s) and write (520 MB/s) performance in all capacities. This comes with optimized random read and write performance across all QD and QD1 and QD2 enhanced for client PC use. With TurboWrite, write speeds are significantly accelerated during data transfers by creating a high-performance write buffer on the SSD. 

This is one of the best external hard drives on the market.
