The Pioneer APS-SE20Q has 512 MB DDR3. DRAM makes drive work faster, but also more expensive.

The Pioneer APS-SE20Q 2Tb due to the high density of memory chips requires installation of additional heat sink. This would lower temperature of the controller and memory. Some motherboards already has additional cooling above and below the storage to enhance performance during times of high loads.

The APS-SE20Q 2Tb has write speed 3000 Mbps, maximum read speed 3400 Mb/s. Storage run on Phison PS5012-E12S-32 controller and M.2 3.0 x 4 high-speed serial computer expansion bus standard. The memory type is Micron 3D QLC.
