I have new iMac 27" 1TB fusion (received Jan 2013) with thunderbolt and USB 3.0 and old MacBook Pro (late 2009) 500 GB Hard drive (which is about 80% utilized) with USB 2.0 connections.
Question: I need to move all my iPhotos (thousands of photos) and iTunes (decent size music collection) from my MacBook Pro to the new iMac. What is best way to do this with the following clarifications?
1. If need to purchase an external hard drive, I want to also keep a copy of all my photos and music on that HD (for back up purposes) so that I can REMOVE them from my MacBook to significantly reduce files on MB hard drive. My MB Pro is sooooooo SLOW now (ugh).
2. Is there an external HD available that has both USB 2.0 and thunderbolt options? Or do you need to purchase some kind of USB 2.0 to thunderbolt adapter ?? I do have an older external HDs that has a USB 2.0
Please advise with any other options I am not thinking of as well, thanks!
