System Requirements

While the Echo Express III-R chassis requires no drivers, the expansion cards

you install do; Thunderbolt-compatible drivers to enable it to work properly

through the Thunderbolt interface are required. More information on which

cards are compatible with Echo Express III-R is available at:

* To support more than two PCIe controllers, Windows requires a Thunderbolt

2 interface in both the computer and the expansion chassis. Note that some

PCIe cards have a bridge to multiple controllers, so it is possible for a single

dual-controller PCIe card to reach the limit if not connected via Thunderbolt 2.

Not all Mac-compatible PCIe cards are also compatible with Windows.
