In this guide to the best external hard drives for Macs, we look at the top devices for plugging in and expanding the storage space of your Mac or MacBook.
While there's a lot to love about Macs, iMacs and MacBooks, they are also tricky to manually upgrade, which means if you run out of space, it isn't too easy to open them up and pop in a bigger hard drive. While you can look into taking your Mac to an Apple Store (or an Apple-approved vendor) to perform the upgrade, this can end up being pretty costly.
So, one of the more affordable (and easiest) ways to expand the storage space of your Mac or MacBook is to use an external hard drive, and this list of the best external hard drives for Macs will help you choose the best drive for your needs.
An external hard drive is essentially a hard drive that comes enclosed in a case. It plugs into a Mac via a cable.
The other major plus is the portability of an external hard drive means you can take it with you and plug it into another device for instant file swapping – handy if you swap between PCs and Macs regularly.
When looking to buy the best external hard drive for Macs for your needs, you should consider how much capacity you need. External hard drives come in all shapes and sizes, and you don't want to pay too much for space you'll never need, but neither do you want to cheap out and run out of space all too quickly.
Speed is also important. SSDs are faster than traditional hard drives, and you should consider what cables they use as well. USB 3.0 is fast, but Thunderbolt is faster. If you want to store lots of large files on your external hard drive, then consider going for the fastest drive you can afford.
In this guide to the best external laptops for Macs we take that into consideration - as well as ease of use, affordability and dependability. This last consideration is perhaps the most important, as when you're entrusting your important files to an external hard drive, you need to be confident that it won't break and lose your data.
