I currently have the 1st generation Belkin Thunderbolt dock connected to my 2011 MacBook Pro. I haven't had any real complaints other than the half speed USB 3.0 ports. This wasn't an issue when I was running spinning disks that couldn't go above the 170 MB/s max. However Ive begun to use external SSDs and I would like to take advantage of the speeds. The updated Belkin dock supports full 5 Gbps USB 3.0, however that dock is Thunderbolt 2 and my Mac is Thunderbolt 1. Does anyone know that when the dock is connected over Thunderbolt 1 does it throttle back the speeds or do they run full speed. The other reason for upgrading is that the other thunderbolt port on the dock is being used by my monitor and I would like to regain that extra Thunderbolt port.
