APS-SE20Q (500Gb) produced by Pioneer support PCIe 3 that is undoubtedly slower than PCIe 4.0. The maximum write speed is 3000 Mb/s, that is pretty good for this expansion standard. The Internal SSD can write 200 TBW, that is bad in comparison with closest competitors. After evaluating all the facts, Pioneer APS-SE20Q 500Gb has more cons and we do not recommend to have it.

Pioneer APS-SE20Q-500 Internal SSD Review


The Pioneer APS-SE20Q has 512 MB DDR3. DRAM in their controller help to increase input/output performance and endurance.

The Pioneer APS-SE20Q due to the low density of memory chips may run with no additional cooling systems. Some motherboards or laptops already has thermal pads above or below the storage for better productivity during heavy loads.

The Pioneer APS-SE20Q 500Gb has write speed 3000 Mb per second, maximum read speed 3400 Mb per second. 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.
