I highly recommend this adapter! Easy to set up. Works with Windows, Mac, and Linux. And works with Synology DS920+ (which is also built on Linux). Installed on my DS920+ I get it's full speed. Running wonderfully since Mid February.

Runs perfect

Doesn't require any weird pro-grade server backplanes to connect, just a regular PCI Express slot If drivers are needed, they can be downloaded as a bundle beforehand and installed offline SFP+ ports accept a few varieties of transceiver, so you don't even need to replace your ethernet wiring to use this
