Technical Notes

  • Performance in a Thunderbolt to PCIe card expansion system limited by maximum 40Gbps Thunderbolt PCIe bandwidth of 2800 MB/s. PCIe bandwidth of Thunderbolt 2 is about half the bandwidth.
  • You may install one SSD now and add a second one later without needing to reformat the existing one. Only 2280 (80mm — the most common length) length M.2 SSDs are supported. M.2 SSDs longer or shorter than 80mm don’t fit.
  • 2.5Gb/s and 5Gb/s speeds are supported when used with NBASE-T compatible (multi-Gigabit) switches.
