Technical Notes

  • While the Echo I Desktop features a 40Gbps Thunderbolt interface, some Windows computers equipped with Thunderbolt 3 use an x2 PCIe lane implementation of Thunderbolt 3 technology that limits PCIe performance to 20Gbps.
  • Power supply will operate as low as 90VAC, with linear power derating from 400W @ 115VAC to 320W @ 90VAC.
  • Full performance requires the use of the included 40Gbps Thunderbolt cable, other 40Gbps (not 20Gbps) Thunderbolt cable, or any Thunderbolt 4 cable; look for the Thunderbolt icon and the number 3 or 4 on the connector housings to identify 40Gbps Thunderbolt cables.
  • ThunderLok 3 compatible specifically with Sonnet 0.5- and 0.7-meter Thunderbolt 3 cables.
