External Hard Drives for Macs

Mac users need to sync an external hard drive with their computer to use Time Machine, Apple's built-in file backup system. Shoppers can find and choose the right Mac hard drive by thinking about storage and portability needs.

To figure out what size hard drive you should buy, think about how much computing you do each day and how many files you save. If you're a heavy user, consider buying a drive with terabytes (TB) of available storage. You'll be able to save an entire system to a device with that much room, so if you need a new computer, you will be able to reinstall everything as it was previously.

These units are beneficial to people who work in creative industries and have libraries that are too expansive for a single Mac external hard drive. For example, a photographer who has hundreds of thousands of pictures saved on his or her desktop won't be able to back everything up with a smaller unit.

Casual consumers should consider drives with a few hundred gigabytes (GB) of space. Buying a device with TBs of data storage would result in a great deal of wasted space for users who only have a couple thousand files that need to be saved.

If you plan on bringing your external Mac hard drive everywhere you go, you'll want to purchase a unit that is light and damage-resistant. Some drives are smaller than most tablets, while other devices are large enough to be confused with video game consoles. If you're prone to damaging your gadgets, consider a drive with pads and shock protectors to defend against significant bumps and bruises.

Time Machine is a convenient program to help ensure that every file is saved, and buying the right Mac hard drive can help Mac users make the most of the program.
