The Silicon Power US70 has SLC Caching DRAM Cache. Dynamic random-access memory (DRAM) in their controller help to improve I/O performance and endurance.

The Silicon Power US70 2Tb due to the high density of memory chips require the installation of additional heat sink. This would lower temperature of the memory chips and controller. Some motherboards from the factory has additional cooling below and above the SSD to enhance performance during heavy loads.

The Silicon Power US70 has write speed 4400 Mb/s, maximum read speed 5000 Mb/s. Storage run on Phison PS5016-E16 controller and M.2 4.0 x 4 high-speed serial computer expansion bus standard. The memory type is 3D Nand.
