Toshiba Announces New BGA SSDs Using 3D TLC NAND
 

Toshiba has announced a new generation of BG series single-chip SSDs, with a newer controller and expanded capacity options thanks to the adoption of 3D NAND. The BG series is Toshiba's SSD solution for tablets and ultrabooks that need a smaller form factor than a M.2 2280 module but higher performance and capacity than eMMC solutions.

Toshiba's BG1 series was first previewed at CES 2015. That first generation uses a PCIe 2 x2 link and implements the NVMe 1.1a protocol. The BG1 is available in capacities of 128GB and 256GB either as a 16mm by 20mm BGA package integrating both the SSD controller and NAND flash, or as M.2 2230 removable modules.
