I'm currently using a lacie 1tb rugged thunderbolt drive in my 2011 macbook pro, but the speeds are subpar. I strictly use it for lightroom, but I'm constantly having difficulties when switching between multiple images it takes a bit to load and then lightroom locks up momentarily while I get to watch the beachball spin around. I assumed thunderbolt would've been faster than usb granted thunderbolt is rated up to 10Gbps but I'm not sure if it's the drive that's inside the lacie that's the bottleneck if its possibly a 5400rpm drive or ? So at the moment I'm contemplating swapping out the drive and putting an SSD in there although I've read about it bottlenecking still, but if I can achieve at least 350-400+ speeds that's fine for me. Just not sure where to go from here. Keep in mind that I'm also contemplating upgrading to a 2012MBP since those have USB 3. I've read a couple of threads on here and it seems common that a lot of people are recommending USB 3 over Thunderbolt, why exactly is this? Regardless, what would be the cheapest and best route that would give me the most significant speed increase at this point? Sell the entire Lacie and buy something else entirely or swap for an ssd?
