The Kingmax PX3480 has Nanya 256 - 1GB DDR3. Dynamic Random-Access Memory makes storage faster, but more expensive.

The PX3480 512Gb due to the low density of memory chips can operate without further heat sinks. Some motherboards already has additional cooling above and below the storage to improve performance during times of high loads.

The Kingmax PX3480 has sequential write speed 3000 Mbps, maximum read speed 3400 Mbps. SSD works on Phison PS5012-E12-27 controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The NAND memory type is Toshiba TLC.
