The Kioxia RD500 has 1GB DDR4. Dynamic Random-Access Memory makes drive faster, but more expensive.

The Kioxia RD500 due to the high density of memory chips require the installation of additional heat sink. This will lower temperature of the controller and memory. Some motherboards already has thermal pads above and below the drive to improve performance during heavy loads.

The RD500 2Tb has sequential write speed 3200 Mb per second, read speed 3400 Mbps. NVMe run on Phison E12 ? controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The NAND memory type is Toshiba TLC.
