M.2 SSD

×

SSD performance is also affected by the PCI Express version. SSD speeds will only operate at lowest PCI Express version to avoid bottlenecks, it is recommended to match the PCIe version supported by your ASUSTOR NAS with your SSD. For example, installing a PCIe 4.0 SSD into a NAS that supports PCIe 3.0 or installing a PCIe 3.0 SSD into a NAS that supports PCIe 4.0 will cause your SSD to run at PCIe 3.0 speeds.

RAID reconstruction may not proceed smoothly if mixing drive models and brands. Please try to use drives of the same model to create a RAID array.

M.2 SSDs vary widely in construction, cooling, size between brands, and product lines. Please refer to the compatibility list below to find out if an SSD needs heatsinks.


  • Flashstor (FS67), Flashstor Gen2 (FS68):
    • Please install ASUSTOR heatsinks by ASUSTOR. (Click here to purchase)
    • You can also choose to install a commercially available heatsink with a size below 70x22x4.5 mm and must be installed on the obverse of the SSD.
  • Lockerstor (AS66), Lockerstor Gen2 (AS67), AS54:
    • Please install a commercially available heatsink with a size below 70x22x4.5 mm and must be installed on the obverse of the SSD.
  • Lockerstor (AS65), Lockerstor Pro (AS71, AS71R), Lockerstor Gen3 (AS68):
    • Please install a commercially available heatsink with a size below 70x22x12 mm and must be installed on the obverse of the SSD.
  • AS-T10G3:
    • Please install ASUSTOR heatsinks by ASUSTOR. (Click here to purchase)
