Pros and cons

According to our solid state drive (SSD) expert
  • This SSD has a built-in heatsink that actively processes the heat and keeps the drive cooled.
  • You can insert this SSD in an M slot of a motherboard or laptop with NVMe/PCIe support without an extra cable.
  • The WD Black SN850X 4TB Heatsink NVMe SSD has a high 7300MB/s read speed, so you can boot your computer and applications very quickly.
  • This M.2 SSD doesn't fit on every motherboard due to the M key, so make sure the connectors match.
