Is Intel Optane FINALLY Worth It? Optane H10 Tested!


The Intel Optane H20 has 256MB DDR3 and 32GB Optane. Dynamic random-access memory (DRAM) in their controller help to improve input/output performance and endurance.

The Intel Optane H20 due to the low density of memory chips able to last with no additional cooling systems. Some motherboards or laptops designed with thermal pads above or below the SSD for improving performance during times of high loads.

The Intel Optane H20 512Gb has sequential write speed 2100 Mb per second, sequential read speed 3000 Mbps. It run on Silicon Motion SM2265 controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The NAND memory type is Intel 144L QLC.
