Evaluating Your Options
Cloud-based storage options are great, but they aren't ideal for large files. For only pennies a gigabyte, there's no reason not get an external drive. For less than $100 you can get a 1 terabyte drive -- that's 1,024 GB -- that fits in the palm of your hand.
USB flash drives are also an option, as are the ridiculously compact Micro SD cards. They don't offer quite as much storage, but for some people, 32 or 64 GB can be sufficient.
