Can someone please tell me what is the benefits of using just one of the 4gb plugs instead of both? right now at my job everyone is using just one?

everyone at my job has mac pros with the fiber cards installed in them but everyone is only using one of the two fiber plugs on the card? is there a benefit to using both of the plugs? just please explain it to me if it would be worth it to have both fiber plugs in use or if one will do it? i work for television network and we transfer a lot of data back and fourth mostly graphics videos and audio?

    Two connections has twice the speed as one.
    Consider each as an individual connection. So a single 4Gb requirement uses one, but when you need more bandwidth, use two.

  • Fiber switches are quite expensive. So at the head end, every port used costs money. A couple of years ago all fiber cards were 2GBps, and final cut worked fine on two of them (4GBps) - depending on your video format and quantity of drives in your raids. So for many people, using both 4GBps ports (8GBps) might be overkill and cost prohibitive. It depends on your usage and funding.
