An external drive is an excellent way to create on-site backups of your data.  External drives are quite small and can function perfectly for taking your data with you and sharing on other host computers.  Often times, organizing large files, such as video projects, images, audio, etc. are more conveniently stored on an external drive, especially when local disk space is a consideration.  Using an external drive is one of the easiest ways to transfer a disk image to a new drive in the effort of upgrading one’s primary drive.

For my personal situation, which was to create an image of my existing drive and transfer it onto an upgrade drive, I decided that an external drive was better, faster, cheaper.
