"Samsung set the bar pretty high when they introduced the 840 EVO. Despite its use of 3-bit (TLC) NAND, this consumer-grade drive delivered performance much like that of its higher-end sibling, the 840 PRO. With the 850 EVO, Samsung has raised the bar even further. By utilizing their new MGX controller and 3-bit 3D V-NAND, the company has been able to cut power consumption while improving both the endurance and performance of the drive.”
