System Requirements

While the Echo Express SE I chassis requires no drivers, the 
expansion card you install does; 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 SE I 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.
