Is Intel Optane FINALLY Worth It? Optane H10 Tested!


The Intel Optane H20 has 256MB DDR3 and 32GB Optane. Dynamic Random-Access Memory makes SSD work faster, but more expensive.

The Intel Optane H20 due to the low density of memory chips may operate without extra heat sinks. Some motherboards designed with additional cooling above or below the drive for better productivity during heavy loads.

The Intel Optane H20 1Tb has maximum write speed 2100 Mbps, maximum read speed 3000 Mb per second. It works on Silicon Motion SM2265 controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The NAND flash memory type is Intel 144L QLC.
