The Thunderbolt PCIe expansion chassis have been tested and certified by Apple and Intel for Thunderbolt compatibility. However, in order to use this device, a compatible PCIe card must be installed. Also, that card's driver must be compatible with requirements for Thunderbolt technology (e.g. hot-plug support and recovery from sleep).

Please download the latest drivers for your PCIe card from the corresponding manufacturer's website before attempting to use the card in the external Thunderbolt PCIe expansion chassis.

If a card is not on the compatibility list below, it does not necessarily mean that it is incompatible, it just means that we have not had the opportunity to test it in our lab and haven't received any user reports so far. If you would like to send us a card for testing or report a card that you are using yourself, please let us know.

PCIe Card Interface & Speeds

PCIe Interface

The PCIe interface can affect both the compatibility and the speed. If a card requires 8 PCIe lanes, it might not work at all in an enclosure with only 4 PCIe lanes. Check with the PCIe card manufacturer for more information about backwards compatibility. If a PCIe 2.0 x8 card is installed in a PCIe 3.0 x2 enclosure, it might be compatible and work OK but the performance will be limited to PCIe 2.0 x2 (~770 MB/s), due to the limited amount of PCIe lanes.

  • Thunder2 PCIe Box : PCIe 2.0 x4 (~1375 MB/s)
  • Thunder3 PCIe Box : PCIe 3.0 x4 (~2750 MB/s)
  • Node Lite : PCIe 3.0 x4 (~2750 MB/s)
  • Node Duo : PCIe 3.0 x2 per slot (~1375 MB/s per slot)
  • Node Pro : PCIe 3.0 x4 (~2750 MB/s)

Thunderbolt Interface

The speed of the Thunderbolt connection depends on the computer and on the Thunderbolt version. Using multiple devices in a daisy chain simultaneously can also affect the speeds.

  • Thunderbolt 1 : 770 MB/s
  • Thunderbolt 2 : 1375 MB/s
  • Thunderbolt 3 : 2750 MB/s

Some Thunderbolt 3 laptops are designed with only two PCIe lanes for the Thunderbolt interface. To reach the maximum of the Thunderbolt 3 interface at 40Gbps, four PCIe lanes are required, so having only two lanes will effectively cut the speed in half and you will only get 20Gbps. For laptops from Dell, check this page at www.dell.com. For laptops from Lenovo, have a look at this article on www.reddit.com. For other laptops, check your documentation, do a search on Google or contact the manufacturer for more information.
