Technical Notes

  • ThunderLok 3 compatible specifically with Sonnet 0.5- and 0.7-meter Thunderbolt 3 cables; Sonnet 1- and 2-meter Thunderbolt 3 cables require ThunderLok 3L.
  • While the Echo Express SE IIIe features a 40Gbps Thunderbolt 3 interface, some computers equipped with Thunderbolt 3 use an x2 PCIe lane implementation of Thunderbolt 3 technology that limits PCIe performance to 20Gbps.
  • Full performance requires the use of the included 40Gbps Thunderbolt 3 cable, other 40Gbps (not 20Gbps) Thunderbolt 3 cable, or any Thunderbolt 4 cable; look for the Thunderbolt icon and the number 3 or 4 on the connector housings to identify Thunderbolt cables.
  • Second Thunderbolt port supports USB 3.1 Gen 1 (5Gb) or Gen 2 (10Gb) devices when connected with proper cable or adapter (sold separately).
