The Kioxia XG8 has LPDDR4. DRAM makes SSD work faster, but also more expensive.

The Kioxia XG8 1Tb due to the low density of memory chips can operate without additional heat sinks. Some motherboards or laptops already has thermal pads above or below the drive for improving productivity during times of heavy loads.

The Kioxia XG8 1Tb has maximum write speed 5800 Mbps, maximum read speed 7000 Mb per second. SSD operate on Kioxia TC58NC0L1XGSD controller and M.2 4.0 x 4 high-speed serial computer expansion bus standard. The NAND flash memory type is Kioxia BICS5 TLC.
