Transfer duration for appleTV -> usb drive


I’ve recently upgraded my 140 GB appleTV with aTV Flash. I’ve decided to use an external 1TO hard drive for primary drive.
I’ve got 120GB of movies to transfer from the internal appleTV to the new drive. How long will that take roughly?

Thanks in advance…

120GB of data will take quite a bit of time to transfer. Expect this to take at least 4 hours. The AppleTV will restart automatically when complete.

The transfer is done, it took 3 hours in total.
