APS-SE20Q (1Tb) produced by Pioneer may work on PCIe 3.0 that is undoubtedly slower than PCIe Gen4. The sequential write speed is 3000 Mbps, that is okay for this expansion standard. The NVMe can write 200 TBW, that is not much in comparison with rivals. When everything is weighed in the balance, Pioneer APS-SE20Q 1Tb is a well-balanced SSD.

+ Pros

  • Good writing speed
  • Capacity

- Cons

  • PCIe 3.0
  • Writing speed

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

The Pioneer APS-SE20Q 1Tb due to the low density of memory chips may function with no additional cooling systems. Some laptops or motherboards already has additional cooling below and above the drive to enhance productivity during times of heavy loads.

The APS-SE20Q 1Tb has sequential write speed 3000 Mb per second, read speed 3400 Mb per second. NVMe operate on Phison PS5012-E12S-32 controller and M.2 3.0 x 4 interface standard. The memory type is Micron 3D QLC.
