Best rugged external hard drive for Mac

A hard-hitting external HDD

Specifications

Capacity: Up to 5TB
Interface: SuperSpeed USB 5Gbps (USB 3.1 Gen 1)
Data transfer speed: Up to 135MB/s (read), 125 MB/s (write)

Reasons to buy

+
IP54 shockproof, dust and waterproof
+
Up to 5TB of external storage

-
Only splashproof

SanDisk Professional G-DRIVE ArmorATD is a 2.5-inch conventional drive mechanism that has been elegantly engineered into an aluminium case and that’s had a rubberised bumper placed around it to further cushion it from physical abuse. It also has the IP54 dust and water protection rating (ie it’s only ‘splashproof’).

The speed of this unit is around 25% of what we’d normally expect from a Gen 1 SSD and 15% of a Gen 2 design. When you factor in that the SSD is likely to be lighter and more shock-resistant, the ArmorATD is relying on its price per TB to make that deal. It isn’t the cheapest, but it is high quality, and it comes with a three-year warranty.

The best external hard drive for Mac by speed

A fast SSD drive that's fast as lightning

Specifications

Capacity: Up to 4TB
Interface: Thunderbolt 3, USB 3.2 Gen 2
Data transfer speed: Thunderbolt3 R/W up to 2700MB/s, USB3.2 R/W up to 900MB/s

Reasons to buy

+
Thunderbolt3 and USB-C compatible
+
Outstanding performance
+
All-metal construction

Reasons to avoid

-
Expensive, especially in Europe
-
No pouch or place to store cables
-
Lacks USB-A cables

The T-Create Classic is a Thunderbolt and USB 3.2 compatible drive built to a very high standard. While the minimalist milled-from-solid-aluminum approach keeps the SSD inside safe, the enclosure isn’t especially light, and the drive weighs 180g, including the cable.

Avoiding smaller capacities, the Classic comes in 1TB, 2TB or 4TB options, and our review was performed with a 2TB drive. It’s designed to excel when connected via Thunderbolt, managing speeds of up to 2700MB/s, meaning spending the not-insignificant asking price of this hardware is probably only worth it if you generally use Thunderbolt equipment computers, like most modern Macs.

Best compact external hard drive for Mac

The tiniest SSD drive

Specifications

Capacity: Up to 1TB
Interface: USB Gen 3.2 2x2
Data transfer speed: Up to 2GBps (read), 1.7GBps (write)

Reasons to buy

+
Good performance
+
Has a carabiner hole
+
Lightweight
+
Three-year warranty

Reasons to avoid

-
Only available in 512GB/1TB capacities
-
USB 3.2 Gen 2x2 still a rarity
-
More expensive than the competition
-
No IP rating

The Netac ZX20 is a portable solid state drive that is lightweight, fast, compact, reasonably solid and borrowed that orange carabiner hole from a popular rival: a useful feature to have for anyone who wants to secure their most precious data storage device. It is not, however, a water-resistant device. It still feels reasonably solid but be aware of its limitations (even if it includes a three-year warranty).

Netac claims that the drive should reach read/write speeds of up to 2GBps/1.7GBps thanks to its USB 3.2 Gen 2x2 interface. It is absolutely tiny (71.5 x 43.5 x 8mm) and is probably as thin as it gets given that you still need to account for the thickness of the USB-C connector.

Best value external hard drive for Mac

Great value for money

Specifications

Capacity: Up to 4TB
Interface: USB 3.2 Gen 1
Data transfer speed: 145MBps (read); 152MBps (write)

Reasons to buy

+
Type-C cable
+
Great value for money
+
3-year warranty

Reasons to avoid

-
Micro-USB port
-
No bundled software

The Canvio Flex is categorized as specialty storage because it carries a long three-year warranty and comes with a Type-C cable, although puzzlingly the device itself has a micro-B USB connector. We’d love to have seen Toshiba use a USB Type-C connector instead, but every cent counts at the lower-end of the market, and aiming for that side of the market makes the Canvio Flex very affordable.

It is reasonably compact (80 x 111 x 13.5mm) and light (149g) but its dimensions are constrained by the fact that it is, at its heart, a 2.5-inch hard disk drive.

The best external hard drive for Mac by capacity

An external drive with massive storage capacity

Specifications

Capacity: Up to 22TB
Interface: USB 10Gbps (USB 3.1 Gen 2)
Data transfer speed: Up to 280MB/s (read), 280 MB/s (write)

Reasons to buy

Up to 22TB of external storage
+
Cheaper than the previous design
+
Pre-formatted for Mac

Reasons to avoid

-
Lacks USB-A cable
-
No software utilities

The SanDisk Professional G-DRIVE Desktop Drive is meant to live on a desk and provide a localised means to secure data and expand the internal capacity of a laptop or desktop system.

The two big selling points here are the quality of construction and the dramatic amount of capacity potentially on offer, going up to an impressive 22TB. It is, however, one of the more expensive ways to get extra space, and it's also relatively slow compared to SSD drives. In our review hardware, the 12TB model could reach read/write speeds of 250MB/s for both.

Best external hard drive for Mac: FAQs

Should I buy SSD or HDD for Mac?

When selecting the best external hard drive for either Mac or PC, your choice will depend on your budget and what you’re after. The best SSD (solid-state drives) traditionally have faster read and write speeds and a more robust build, but they’re expensive, and offer much less storage space than similarly priced HDDs (hard disk drives).

If money is an issue, HDDs are the better option as you can get huge storage - we’re talking TBs, for the price of GBs on the SSD side of the aisle. The main drawback is they’re more fragile than SSDs since they have spinning platters of data inside them, rather than a total absence of moving parts.

What is the difference between external and portable hard drives?

The main difference is how the drive gets its power. Portable drives get it from the cable used to connect them to your Mac, whereas external ones usually get it from a separate power supply. This means an external drive is fine if you’re close to an electrical outlet, and a portable drive is better if you plan on accessing the data while on the go, i.e., they’re a great companion for laptops. 

Will an external hard drive improve performance on Mac?

It will really depend on how you use it. For instance if you offload the files contained on your Mac’s internal hard drive and place them on your new external drive, then the space you’ve freed up could be used by your operating system, potentially speeding up your Mac’s responsiveness in the process. If you just use it to create and add more files, albeit on a separate drive, then the difference in speed might only be negligible. 

How to choose the best external hard drives for Mac for you

When choosing the best external hard drive for your Mac, you must consider other things beyond storage capacity and price. 

Chiefly, your choice comes depends on your needs, which are likely to be very specific and possibly even unique. Will this be, for instance, a drive used as an extension to your iMac, and you’re on a tight budget? In which case, you’ll likely be better off with an external HDD, something you can plug in to power, with plenty of storage space, for a reasonable amount of money.

If however, you’re more an on-the-go person, who likes to work with your MacBook wherever you find yourself, from a hotel room, to a coffee shop, or even at the beach, then a portable SSD would be the better option: these will be powered directly from your laptop, and no moving parts means they are much more sturdy. But they are much more expensive.

Finding one that’s affordable and has enough storage space – a minimum of 1TB is highly recommended – for your present and future needs is ideal, even if you have more than enough money to splurge for something expensive.

Another deciding factor, however, is the connection. Many external hard drives have USB 3.0 connections, but since even the best MacBook and Mac accessories rely on the power and data transfer speed of USB-Cs, USB Type-C or Thunderbolt 3 or 4 connections are certainly favorable. 

If you’re storing critical files, especially for work, consider getting one with more robust security features. There are other things, including a rugged build if you plan on taking it out in the field with you, while the best portable SSDs are ideal if you plan to travel around with it. We also recommend pairing your device with the best cloud storage and best backup software for additional data security.

How we test the best external hard drives for Mac

Although choosing the right drive can be very subjective, there are some parameters which can be useful to help gauge and compare the various devices we review. The most obvious one is price, of course - we all love a good deal, and price per GB or TB is a good indication of that. But this only tells us part of the story.

As you’ve seen through this list, we often mention the disparity between HDD and SSD when it comes to that value, primarily because HDD are much cheaper (being an older technology, that makes sense), and SSD are more expensive, but much studier, as they have no moving parts.

So it’s a balance between price, sturdiness, size, whether or not you need to drive to be powered by your Mac, or have to be powered independently, and perhaps most importantly, how quickly your Mac can read and write to that drive, i.e., how fast it can access and create information. And that depends both on the speed of the drive, but also on the type of cable you use. 

All the best MacBook Pro devices, MacBooks and desktop Macs (iMac, Mac Mini, Mac Pro) come with one or more Thunderbolt ports which are also compatible with USB Type-C. So we look not only at the versatility and general performance of the drives - across several benchmarks - but also their relevance to specific use cases, after-sales and warranty, and sheer value for money.
