The Silicon Power UD70 has SLC Caching DRAM Buffer. DRAM makes storage work faster, but more expensive.

The UD70 500Gb due to the low density of memory chips able to work without further heat sinks. Some motherboards already has thermal pads above or below the storage for better productivity during times of high loads.

The Silicon Power UD70 has write speed 3000 Mbps, read speed 3400 Mb per second. Storage works on Phison PS5012-E12S-32 controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The NAND memory type is Micron 3D QLC.
