      What types of PCIe cards can be used with the ExpressBox 1T?

      Maximum PCIe card length for ExpressBox 1T is 7.75" long. Check the Thunderbolt PCIe Card Compatibility for a list of cards that have compatible drivers. If your PCIe card is not on this list, contact the card manufacturer to ask if they have a Thunderbolt 2 Compatible driver.

      Can the Magma Thunderbolt 2 Interface add-in card be used in a Mac Tower?

      No, it will not work as a add-in PCIe card in a Mac Tower.

      Do older Thunderbolt devices on a Thunderbolt 2 daisy chain affect performance?

      Yes. If you have a mix of generations on a Thunderbolt 2 daisy chain, make sure that the Thunderbolt devices sit after the Thunderbolt 2 devices on the chain. Anything placed after a first generation Thunderbolt device will operate at Thunderbolt speeds.
