Kioxia BG5 1TB SSD Review

The BG5 comes in two module sizes, M.2 2230 and the more familiar M.2 2280, like our review sample above. The 1TB 2280 drive is a single-sided design with all the components sitting on one side of the PCB.

Under the product sticker is a single 1TB package of Kioxia's BiCS5 112-layer TLC 3D NAND (coded TH58LKT3X25BAEG). There's a lot of empty real estate between the NAND package and the tiny Kioxia controller, labelled TC58NCOL1BGSB at the other end of the board.
