Technical Notes

  • Full performance requires the use of the included Thunderbolt cable or any Thunderbolt 5, 4, or 3 cable; not Thunderbolt 20Gbps cables. Look for the Thunderbolt icon and the number 5, 4, or 3 on the connector housings to identify 40Gbps or better Thunderbolt cables.
  • ThunderLok compatible specifically with Sonnet 0.5- and 0.7-meter Thunderbolt cables.
