I've been researching the Thunderbolt docks that are on the market and I've come to the conclusion that none of them are perfect. Each model seems to have some major flaw that prevents me from buying it. Whether it's the fact that it makes a noise when unplugged, or no HDMI output, or slow USB 3.0 connections, there just seems to be issues with all the brands. So what is the best one out right now? I have a 27" Thunderbolt display that it will be daisy chained off of and I basically wanted it to expand the USB 3.0 ports so that I can leave my external drives plugged in all the time. Adding a second display in the future is second priority.
