Since I have to record my own recital tomorrow I had to pull out my recording gear and discovered that my Macbook Pro only has USB and Thunderbolt jacks and the external drives I have are all firewire. I ordered a 1TB SSD drive on Amazon for free same day delivery and I'm running a test session to make sure that 45 minutes worth of recording isn't going to do anything weird or crash my machine. 20 minutes in and its going fine.
