Gets the advertised speeds. Easy install.
Worked out of the box on FreeNAS 8.3. Worked with Intel drivers on CentOS 6. Speed is comparable to other 10gbit solutions.
Does exactly what it is supposed to. Setup was as easy as any other networking card, except ten times the speed! We put one of these on our server, and on our video editing workstation. We have a Netgear 10gbe XS708E switch between them. They are all connected through shielded CAT7. In a realistic day-to-day use, it's usually around 300 to 500 MBps. In some specific scenarios (large ISO files, etc) it goes to over 700MBps. This easily maxes out the SSD on the workstation! We no longer have to copy video files locally at our studio, instead they can remain on the server. It was very easy to set up link aggregation. I managed a peak of roughly 1.8GBps transfers to the server in specific scenarios, like setting up a ramdrive, running ATTO, etc.
