I just got a setup I'm going to try, the Seagate backup plus thunderbolt adapter.
I'm going to try to use it on my MBP (late 2011), and from there daisy chain my thunderbolt to display port I currently use to get my Dell u2711 monitor to work.
I bought a thunderbolt cable, and a seagate backup plus 3TB drive (strangely enough, cheaper to buy in pieces rather than the bundled package by seagate)...
Anyway, I hope to set this up and try to use that for my fast off laptop server access (photoshop, premier, AE work).
When SSD comes down in price a bit, I will likely pull the mechanical drive mentioned above off of it and drop the SSD on the thunderbolt adapter (which I've seen will work )...
Anyway, that's a new attempt I'm making. I have slower NAS stuff out there for longer term storage, but I'm hoping this thunderbolt adapter (essentially a thunderbolt to SATA adapter) will prove to be speedy enough for my needs, and relieve my onboard drive of some churn and keep it from filling up all the time.
