There are some interesting things happening in the solid state drive space as of late. A little over a week ago, Samsung said it had begun mass producing its fifth generation 256Gb V-NAND flash memory that could lead to faster SSDs. Now just over a week later, Toshiba is touting a type of flash memory that could significantly increase capacities, too.

Specifically, Toshiba announced the development of a prototype sample of 96-layer BiCS flash, the company's proprietary version of 3D NAND, with 4-bit-per-cell (quad-level cell, or QLC) technology.
