Best external hard drives for Mac in 2024

Get more storage for your Mac by adding an external drive. These are your best choices for adding capacity to your Mac desktop in 2024.

The performance of the Mac is probably the most important aspect of buying a new computer. The second is almost certainly going to be storage capacity.

However, while you can configure storage at the time of purchase, you don't have the opportunity to add any more internally. The exception is the Mac Pro, but that is an oddly specialist device in the Apple range.

If users want more storage, they have a few options. For a start, they could consider trading in and upgrading their Mac, though this is very inefficient.

Cloud storage is always a possibility, but that does rely on you having Internet access. That, and it's very slow compared to local storage.

The best option, therefore, is to acquire some external storage for your Mac. For desktop Macs, it makes a lot of sense since the drives aren't being moved around like you would for the MacBook Pro.

What follows is AppleInsider's best picks for drives of various kinds that you can attach to your Mac and boost your storage capacity.
