The Samsung 840 EVO is one of the best consumer SSDs on the market. The drive delivers good performance for its price. Earlier this year, Samsung launched the 850 Pro that uses the 3D V-NAND that boosts the performance, capacity and reduces power consumption for the SSDs over the 2D planar NAND. We were hoping that Samsung would deliver a consumer drive that also uses same 3D V-NAND as what it has done in the past. Well, our prayers have been answered as Samsung has unveiled the 850 EVO as the successor to the 840 EVO.
