Not sure why they don't have a separate USB port just for doing this so it's a direct transfer instead of transferring through the CPU. Kind of ridiculous. Transferring 600GB at 20MB/s is going to take some time.
If my math is correct it'll be about 10 hours. BLAH
No but seriously, I'm a pack rat with shows and movies etc.
Ah... then you're exactly the right person to understand how I am with files. I've got 5TB of storage in my computer... if I hadn't been saving for the past year to move to Brazil, and thus curbed my file saving, I'd probably be at at least double that. I've got movies, tv shows, music, etc, etc, etc. I could never settle for the USB experience.
