If you work in the creative industry, perhaps as a photographer or video editor, you’ll likely need to store lots of large files. That's a sure-fire way to fill up the hard drive of your Mac or PC, so why not pick up one of the best external hard drives for your Mac or PC to help? 

Using an external hard drive is a fast, dependable and easy way to expand the storage space of your computer or laptop, and they are affordable too.

When choosing the best external hard drive for you, your main consideration should be storage capacity: around 500GB is a good sweet-spot for external storage, though you can buy smaller capacities, as well as larger ones at 1TB or greater if you need to store lots of video. 

Other considerations include speed, portability, price and connectivity – you’ll want to ensure your new external hard drive has the right connection port for the device you want to connect it to. The first generation rectangular USB-A ports are slowly being superseded by the newer, smaller reversible USB-C ports. These are now found on all modern PCs, and Macs. 

HDD vs SSD: which is best?

There are two types of external hard drive: hard disk drives (HDD, also known as mechanical or traditional hard drives) or solid state drives (SSD). An SSD is faster, lighter and less power-hungry, whereas an HDD drive will be cheaper, have a higher capacity – more storage – and are more readily available in shops and online. 

So, if you want to store huge amounts of data while keeping prices low, an external hard drive is the way to go. But if speed is your top priority – for example, if you move a lot of large files, or want to run programs off the drive – then choose an SSD. 

We’ve included both in this best external hard drive roundup.  Right now, our top pick for best external hard drive is the Western Digital My Passport 4TB, which is a mechanical hard drive. We think it offers creatives the perfect balance of speed, reliability, portability and price for both Mac and PC users.

01. Western Digital My Passport 4TB

The overall best external hard drive for Mac or PC

Capacity: 4TB | Interface: USB 3.0

Large capacity
Good data transfer speeds
WD backup software is basic

When it comes to the best external hard drives, look no further than the Western Digital My Passport range. This is the latest model to have launched, coming in sizes from 1TB to 4TB. It features cloud storage and 256-AES encryption, along with WD's own backup software. 

It also offers top data transfer speeds. And while it doesn't quite offer a similar speed to solid state drive devices, the Western Digital My Passport range hits a brilliant balance between high storage capacities and quick file transfers without knocking the price way up.

Samsung Portable SSD T5

02. Samsung Portable SSD T5

The best high-speed external storage device

Capacity: 250GB - 2TB | Interface: USB 3.1 (Gen 2)

Very good performance
Very high capacity
Expensive

The Samsung T5 SSD is a great performing storage device, reaching speeds up to 550 MB/sec, making the most of the USB 3.1 specification. It plugs directly into PCs and Macs with either a newer USB-C port or USB-A, is roughly the size of a matchbox and being a flash storage device, contains no moving parts, so can survive being dropped.

External SSDs may cost considerably more than hard disks, but the extra money and faster speeds go a long way. You’ll be able to easily load edit and save 4K video directly on the T5, which can be very slow with a USB hard disk, you can install applications onto it, or even run an entire alternative operating system off it at full speed, if you’re so inclined.

The downside is the pricing. SSDs give you less capacity for more money, so we don’t recommend the T5 for backup. It’s better to have a bigger hard disk for that and use the T5 in more specialised situations that need all that lovely performance

G-Technology G-RAID with Thunderbolt 3

03. G-Technology G-RAID with Thunderbolt 3

The fastest and largest external hard drive for modern desktop Macs

Capacity: 8TB - 24TB | Interface: Thunderbolt 3, USB 3.1

Lashings of fast disk storage
Easy removal of disks
High price

G-Technology has long been a favourite of Mac creative professionals, and no small part of this is the clever use of silver aluminium that perfectly matches Apple’s iMac casing, keeping desktop areas with a uniform appearance.

The latest incarnation of its G-RAID dual hard disk Thunderbolt product isn’t just a start performer, capable of 440 MB/sec transfer rates in RAID 0, which is pretty incredible for hard disks, but it also gives you a few extras.

There's an HDMI 2.2 port on the back, which routes a video signal for an external display over the G-RAID’s Thunderbolt 3 cable, which has plenty of bandwidth to spare even with the hard disk going at full speed. It also has a USB-C port to connect to Macs or PCs that lack Thunderbolt.

Expect to pay a small fortune for the largest capacities, but thanks to the easy drive removal system, you could always buy a cheaper, lower capacity G-RAID and upgrade it with off-the-shelf hard disks yourself.

Buffalo MiniStation Thunderbolt

04. Buffalo MiniStation Thunderbolt

The most affordable Thunderbolt external hard drive

Capacity: 1TB, 2TB | Interface: Thunderbolt, USB 3.0

Low price compared to other Thunderbolt drives
Limited hard disk performance

If you want to make use of your Thunderbolt port, then this Buffalo MiniStation Thunderbolt is a great option, as it provides twice the speeds of standard USB 3.0 drives. It's also not especially expensive compared to other Thunderbolt drives. This is mainly down to the fact that it's a traditional hard drive, not an SSD, which means it's not quite as fast as it could be – though it will still give you an upgrade to your transfer speeds.

Helpfully, the Buffalo MiniStation Thunderbolt also comes with a USB 3.0 port for connecting to computers that don't have a Thunderbolt port.

LaCie Porsche Design Mobile Drive 4TB

05. LaCie Porsche Design Mobile Drive 4TB

USB-C star

Capacity: 4TB | Interface: USB-C

Fast USB-C connection
Great design
Expensive
You need USB-C ports to take advantage of speed

The LaCie Porsche Design is one of the best external hard drives for Macs on sale today, and comes with both USB Type-C to Type-A and USB Type-C to Type-C connectors, making it a versatile way to expand the storage space of your Mac, regardless of what ports it has. This is also one of the most stylishly-designed external hard drives on this list, and it comes with a large 4TB capacity (with other sizes available as well), and it performs brilliantly.

Adata SD700 External SSD

06. Adata SD700 External SSD

The best cheap external SSD

Capacity: 256GB, 512GB or 1TB | Interface: USB 3.0

Great performance
IP68 rating
No USB Type-C

The Adata SD700 will suit those looking for a rugged storage device that can provide ample capacity without costing too much. It performs superbly well and remains the only SSD we’ve seen that's IP68 rated.

Thanks to the solid state drive that resides in this external hard drive, it's a lot faster than external drives that use traditional spinning hard drives – so you're getting great transfer speeds as well as rugged protection.

It also comes in capacities up to 1TB, so you don't have to worry about missing out on storage space just because it uses an SSD. This Adata drive really does hit all the right notes.

WD My Book Duo

07. WD My Book Duo

The best high capacity external drive for your Mac or PC

Capacity: 4TB - 20TB | Interface: USB-C (Gen 1)

Huge amounts of space
Integrated USB hub
Expensive
Limited performance compared with Thunderbolt drives

If you're looking for the absolute largest capacity external USB hard drive, then the WD My Book Duo Is the one to get, as it now goes all the way to 20TB. 

If you don't mind sacrificing some of the ample storage space you can set the drives up in a RAID 1 array, so you have file backups of your files should one of the drives die. This is an excellent feature if you're going to use this device to back up irreplaceable data, such as your creative work, as it adds a level of protection in case things go wrong.

It provides two additional USB ports on the rear, so you can easily insert flash sticks. The device, which comes with two-year warranty, has 256-bit AES hardware encryption, and automatic backup software (WD SmartWare Pro).

It's also worth noting that the enclosure used is fully serviceable and that WD ships the drive already pre-formatted for Windows users (NTFS), so you'll want to reformat it to work with your Mac.

 LaCie Rugged USB-C

08. LaCie Rugged USB-C

This rugged design is great for storage on the move

Capacity: 1TB - 5TB | Storage Type: Hard Disk | Connector: Type-C | Interface: USB 3.1

Rugged design
Backwards compatible with older USB
Ugly orange casing

Lacie’s rugged hard disk series is instantly recognisable from its orange casing, which is a rubber enclosure that keeps the disk safe from even medium-height drops up to 1.2m, along with your precious data.

According to Lacie it can apparently withstand the pressure of a one-ton car, and is resistant to rain. That makes it a great choice for content creation when you’re out and about, whether you’re participating in daredevil sports, travelling the world, just a bit paranoid or simply clumsy.

External hard drive alternatives

If you prefer your storage to be integrated, it is possible to upgrade to the internal hard drive of your desktop PC or laptop. It certainly isn’t easy though, and Apple has made sure it's pretty much impossible to replace those drives in their devices yourself. 

Cloud storage is another option, allowing you to store your files online, enabling you to access them from pretty much any internet-connected device.
