Toshiba's XG6 SSDs put 96-layer NAND to good use
 

When we reviewed Toshiba's XG5 NVMe SSD, it was one of the fastest drives we'd tested. Although that was the first drive we fondled that came equipped with Toshiba's 64-layer BiCS 3D flash memory, at the time Toshiba had already announced that it had 96-layer chips in development. That's been a year ago now, and the XG5's successor is here. Meet the Toshiba XG6 NVMe SSD. As you've no doubt already assumed, this drive uses fourth-generation TLC BiCS flash, stacking 96 layers of NAND cells in each chip.
