What are people using to connect SSD drives from a camera to Thunderbolt or Firewire?
HighPoint RocketStor RS5212 is a Thunderbolt Dock that will accept two hard drives or SSDs.

I would not use FireWire for SSDs, unless you don't have USB 3.0 and you're on a budget. USB 3.0 is often fast enough to get the maximum out of your SSD, FireWire not.
