        Technical Notes

        1. Windows requires a Thunderbolt 2 interface in the computer and in the expansion chassis to support more than two PCIe controllers. Note that some PCIe cards have a bridge to multiple controllers, so it is possible for a single dual-controller PCIe card to reach the limit if not connected via Thunderbolt 2. Not all Mac-compatible PCIe cards are also compatible with Windows. See thePCIe Card Thunderbolt Compatibility Chart for details.
        2. PCIe cards sold separately.
        3. Compatibility requires the installation of Thunderbolt technology-aware drivers, available from the manufacturer. See our supporting PCIe Card Thunderbolt Compatibility Chart for a list of up-to-date compatible PCIe cards.
        4. ThunderLok compatible with all copper Thunderbolt cables. Not yet compatible with optical Thunderbolt cables.
