ioSafe Rock Just as Well!
I love the IoSafe Rugged Portable 1TB Drives as well! You can RUN OVER these things with you vehicle and they still running. They can get wet, frozen, vibrated to pieces and it doesn’t even phase their operation! They run on USB3, wish they updated to Thunderbolt. They are heavier then most external drives but that’s because of their built. Since they are going back and forth from the MacBook to the Win7 machine, I use Folder Sync Pro on the MacBook to backup my images files. These are great drives that for the outdoor photographer, are a must in my book!
