To find the best external hard drive for your Mac, you need to know how you will be using it. Will you be transferring large files that you don’t want to keep on your iPad or MacBook? Will you be playing audiovisual material off the drive? Will you be backing up files in the field, for instance, while filming with your DSLR or camcorder?
Most portable drives draw power from your computer. However, some larger ones need external power. For the latter, you will need access to an outlet. So, keep power sources in mind when choosing your drive. If you are working on the go, it can also be a good idea to carry a power pack to charge your electronics when batteries run low.
Once you have the best external solid-state drive or hard drive for you, take care of it by storing and transporting it properly. Fortunately, most drives fit easily in laptop backpacks. So, you can carry them without any additional hassle.
