The best external hard drives for Mac can be hugely useful when you've filled up the capacity of your macOS machine's internal SSD. These plug-in external drives can give you gigabytes of additional storage in an instant, so you'll have much more room for photos, videos, music, podcasts and anything else you want to store in digital form.

Two types of technology are covered in our best Mac external drive list: HDD (Hard Disk Drive) devices use the traditional, slower, mechanical technology, so these can't compete on transfer speeds but do give you lots of capacity for not much money; SSD (Solid State Drive), meanwhile, provides faster storage technology with no moving parts for those who want the speed.

As we note in T3's best SSDs buying guide, these drives offer way faster speeds than conventional HDDs, as found in many of the best external hard drives. Insane speed isn't everything though: when it comes to extended storage, capacity is often the most important thing, so it's very much about finding the product that works best for you.

Don't panic though: our buying guide will tell you everything you need to know in plain language. These are quite simply the very best external hard drives for Macs that money can buy, and we'll talk you through the advantages (and occasional disadvantages) of each one.

What you should know before buying an external drive for your Mac

It's 2025, which means that solid-state drives (SSDs for short) are hardly new, but it's still well worth us pointing out that they're a huge variable when you shop for a new hard drive. In fact, they're not technically hard drives, but we're going to ignore that for the sake of clarity.

SSDs are faster and smaller than traditional disc-based hard drives by quite a big margin but, for a long time, they were quite a lot more expensive, too. That's actually still the case, but their prices have come down heavily in recent years, making them affordable if you're happy to settle for lower capacities.

It's still very much the case that if you want the most terabytes of storage that you can possibly get, an old-school HDD will be the best value. However, it'll be much slower to transfer files, so you'll have to weigh up what's more important to you. SSDs are also significantly more portable, thanks to being way smaller, which counts for something.

If you do decide to go with an SSD, it's easy to get bogged down comparing speeds between different drives. It's true that you can spend more to get boosted transfer speeds on the latest and greatest, but trust us that most reputable brands like Samsung or LaCie can be relied upon to provide speeds that will keep you happy as you store files.
