InterfaceiFastest host connection the drive is rated for. The PCIe generation of an NVMe drive is its own field. A Thunderbolt drive that also works over USB uses its Thunderbolt version.

ControlleriController maker and model as named by the maker or a review. On an external drive, the controller of the SSD inside, not the USB or Thunderbolt bridge chip. The bridge chip goes in the source note.
