Facebook asked for denser and cheaper 100TB QLC NAND SSDs during its keynote address at the Flash Memory Summit. Coincidentally, an hour later, Toshiba laid out its ambitious plans to develop 100TB QLC SSDs. Toshiba plans to pioneer the use of QLC (Quad-Level Cell) technology with a new variant of its 64-layer BiCS3 NAND, but the company will also employ its TSV (Through-Silicon Via) technology to boost its die stacking capability, which effectively doubles capacity per package. QLC NAND makes several tradeoffs, particularly in the endurance and performance department, but it will provide more density than even the beefiest new SSDs.
