Video Review

The fastest SSD for gaming, and one big problem..


The DC P5800X 400Gb has no dynamic random-access memory (DRAM) or data about it is not known. Dynamic Random-Access Memory in their controller help to improve I/O performance and endurance.

The Intel DC P5800X due to the low density of memory chips may last without additional cooling systems. Some motherboards designed with thermal pads above or below the storage for better productivity during times of high loads.

The Intel DC P5800X has maximum write speed 7400 Mb/s, maximum read speed 7400 Mb/s. It operate on Intel controller and U.2 2.5" or E1.S high-speed serial computer expansion bus standard. The NAND flash memory type is Intel Optane 2nd Gen.
