Here's a use case: I'm mounting my new LG 4K monitor on the office wall and will run a Thunderbolt to my Mini which is in the closet. For reasons we don't need to get into, the cable run must be at least 20 feet. I doubt I'd need T3 speeds, but can anyone confirm T2 will work fine in this instance? I did notice some reliability concerns with the Corning T2 cables. It might actually be worth it to me to buy an Areca cable, not for T3 bandwidth but, if they're rock solid, to avoid a crapped out cable stuck in my wall.
