For the first time, Samsung has starting producing SSDs using (wait for it) 3-bit multi-level-cell, 3D Vertical NAND flash memory, better known as TLC V-NAND. So, who in the actual hell cares? You might, if you're planning on buying an SSD or computer soon. Samsung's current V-NAND technology has resulted in models like the 850 Pro SSD, which topped all benchmarks and has a 10-year guarantee. But combining V-NAND with 3-bit tech has more than doubled wafer yields, which should result in even cheaper, faster and higher-capacity SSDs. The disks aren't on sale yet, but there's a good chance that one of the first available will be Samsung's recently leaked 850 EVO.
