Toshiba has showered its new BG Series M.2 SSDs, which is tiny measuring just 16 mm x 20 mm. Which is shorter than the shortest M.2 length (30mm) standard currently available. The BG series take advantage of the PCI-Express 3.0 x2 interface, and the NVMe protocol.
These drives are using Toshiba’s BiCS Flash, which is a multi-chip module that combines stacked TLC NAND flash memory with an SSD controller into one package. The BG series come in capacities of 128 GB, 256 GB, and 512 GB. Toshiba will also be selling these drives as chip separately, to notebook manufacturers so that they can solder them directly onto the mainboards of their low-cost ultra-portable notebooks.
