In this roundup, we’ll be reviewing some of the best external hard drives with Thunderbolt 3 support. Before that, a little insight into why they’re important.

Should you be interested in laptops to go with these hard drives, then do check out our round-up of the Cheapest Laptops with Thunderbolt 3.

High-speed data transfer is sometimes an overlooked process by regular users, but if you take a closer look at what some users or professionals transfer, it becomes a very important issue.

So what is high-speed data transfer, and what does it help you achieve in the long run?

Let’s say that you are someone that works daily with a lot of documents or files and need to stack more and more of them, transfer them quickly from one place to another and so forth. If you just use your MAC’s or PC’s internal storage, you can quickly find out how fast it runs out of space.

So, like a learned young-ling, you scour the internet and find out about external storage devices, but you get a lot of configurations about this and that – “This one has a lot of space and it connects with a USB cable, but the Read and Write speed is low. Look, this other product is faster, but it has a Thunderbolt 3 method of connection. I wonder what that is?”

So you quickly read through tons of posts, products details and get to a baseline of “I have no idea of what I was even doing in the first place”.

If you find yourself in that point, then you should first figure out on what exactly are you going use that external drive. For example, if you want it for a PC, go for USB connection, but if you need for a MAC or another Apple product, then you’ll have no choice but to look only in the Thunderbolt categories.

That brings us to what exactly Thunderbolt is.

Started as a joint hardware interface between Intel and Apple, it allows a user to connect an external device or peripheral to a computer or MAC. Among those external devices, we also have hard drives.

Over the years, it went over three periods of growth or changes, starting with the cleverly named Thunderbolt 1 and ending up in the present with Thunderbolt 3. Easy to spell, easy to remember, easy to market. Genius, I know.

While the first two generations were based on the Mini DisplayPort, a port that allowed for audio-video digital interface, the latest model is a more advanced version, while also taking some cues from it’s USB cousin. More precisely, it reuses aspects of the USB-C which helps it to transfer twice as fast as Thunderbolt 2, halves power consumption and is all around a much better hodgepodge of other technologies in one.

Since it first appeared on the market in 2011, the Thunderbolt 3 has gained quite a remarkable popularity among tech developers and it was implemented in many devices, among which we also have the external hard drives. So now that we have the history connection plugged in, let’s move to the main guest of our little show, our top external hard drives.

To get a better understanding of Thunderbolt 3, do check out our previous article What is Thunderbolt 3?.

We will count everything from specifications, user reactions, price and some honest to God, real opinions. Oh, and the list will just be in numerical order, not a top best to worst order. First as a list and further down we get into the details of each external drive.

5. G-Technology G-Raid with Thunderbolt 3

Moving from a sleek design but mediocre abilities to a bulky drive with exceptional results.

What this means is that the G-Technology G-Raid is an exceptional storage unit if you need everything done fast and you want to be able to keep it all in one place.

Unlike our previous entry, the G-Raid has an HDMI interface to boot, besides USB and Thunderbolt 3. And from the looks of it, it seems like it was made specifically for people working in the editing industry.

If you want to, you can search this bad boy out and buy it with the following capacities: 8TB, 12TB, 16TB, and 20TB. From what it looks like, you could fit an entire library worth of movies, songs, and other files and you still would have space for some other things.

In regards to other specifications, the G-Raid is actually comprised of a dual Enterprise-class 7200 RPM hard drive, which explains both space and design. Additionally, it has a small incorporated as not to overheat the unit or any other accidents.

Read and Write and transfer speeds are also quite reliable, as you would expect by now from a Thunderbolt interface. USB 3, just like before is slower but it still does it’s work perfectly and it works more than fine. Both also come in with a cable, for Thunderbolt 3 being a 20 Gbps, and a shorter and slower USB 3 cable.

Our Take

Now, if we are to say what exactly is the highlight with the G-Raid, I would just mention the price. It’s not for your usual consumer and considering all the specifications mentioned I believe you can tell. It was made for people that absolutely require a big depository for large files. If we take that into consideration, I would say that the G-Raid fits the bill more than ok.


Drive type External Hard Drive
Interface Options Thunderbolt, USB 3.0, HDMI
Available Capacities 8TB, 12TB, 16TB, 20TB, 24TB
Dimensions 25(L) x 12.5 (W) x 8.6 (H) cm

  • The drives can be removed and switched.
  • The fan keeps it cool, but it’s also a noisy device.
  • Expensive.
  • It fits only a certain type of customer.

6. MyDigitalSSD Pocket Vault Express PVX Thunderbolt 3 Capsule

That title really is a mouthful, we know. The great people at MyDigitalsSSD bring us a wallet-friendly (both financially and physically) SSD that combines the Thunderbolt 3 tech with PCIe 3.0 x2 NVMe SSD.

For such a small device, it actually has great Read and Write speeds, the data transfer ranging up to 40Gbps and it’s bus-powered. So, again, it powers on only when you connect to a computer, for example, as it doesn’t have its own power source.

This is both a blessing and a curse, as we pointed out in a previous device on this list. While the maximum speed mentioned there is hypothetical, it has been tested out and the surest type of readings and writings are of 1.6 GB for the first and 1 GB for the latter. Which is quite impressive, it sets quite an example worthy to be followed.

Now, on the market, you can find in three types of capacities, that obviously vary in price, depending on their storage capacity.

Aspect wise, the Pocket Vault Express is encased in an aluminum case, it isn’t that big with a length of 10.2 cm and at 88 grams you could even say that it’s as light a feather. It has a sleek design, which even the makers themselves have said that “fits in the palm of your hand”. Basically, easy to carry and to use.

Our Take

As a final word, the MyDigitalSSD Pocket Vault Express PVX Thunderbolt 3 Capsule is a great product that offers mobility and quick spurs of action for whatever kind of activity you are doing. It comes at a somewhat affordable price and it looks like it was made specific to everyone in mind to be able to use it.


Drive type External Hard Drive
Interface Options Thunderbolt 3
Available Capacities 256 GB, 512 GB, 1 TB
Dimensions 102(L) x 48 (W) x 15 (H)mm
Weight 88 grams
OS supported Mac OS X 10.12 or later, Windows 8.1 or later


  • It comes in three variants, all quite cheap.
  • It is a fast data transfer SSD.
  • It only has one port.
  • It’s not that flexible as it as has one connector interface.

7. LaCie Rugged Thunderbolt USB-C Portable Hard Drive

From a long line of Rugged drives, here we have another one, the LaCie Rugged Thunderbolt USB-C Portable Hard Drive.

While it doesn’t fit exactly in your palm, it’s quite manageable, easy to pick, easy to use and even easier to admire the goal they had when chose orange for their casing. I don’t know why, but it kind of reminds of sponge. The most important fact though is does it absorbs your data just as quickly like a sponge.

My previous comments about the case don’t provide the entire context of it’s design.

While the color is an interesting choice, the enclosure is made in a way that it can withstand all kinds of accidents and misfortunes that may come down on the owner.

It’s drop resistant, water-resistant apparently crush-proof, which is perfect if you work in an oil refinery at sea. It’s just the most magical place that you can choose to take a LaCie Rugged with you.

Outside appearances are great and all, but about what’s one the inside? How does that work? Does it even work?

While it has both a USB and Thunderbolt interface, it doesn’t take advantage of that and feels a bit underwhelming.

A nifty trick that the LaCie Rugged Thunderbolt has over the competition is that fact both ports have their own cables included with the product, and the Thunderbolt one is integrated directly in the case. So for anyone that has problems remembering where they put their cables, at least it’s got you covered on that end. That, unfortunately, means that in case it has a problem, it’s not as easy to replace it.

As for how much you can carry with it, the LaCie Rugged has 3 versions, two of which are somewhat bigger and heavier than the first one – physically and in terms of memory. The 3 storage capacities are 2TB, 4TB, and 5TB. The prices for all of these models are quite appealing, especially one that offers so much space.

Our Take

In the end, the LaCie Rugged hard drive is a commendable sponge looking drive, that can serve any kind of needs and holds up really well on the market, even if the main requirements aren’t that special.


Drive type External Hard Drive
Interface Options Thunderbolt 3, USB-C
Available Capacities 2TB, 4TB, 5 TB
Dimensions 15(L) x 9.1 (W) x 3.4(H)cm
Weight 0.4 kg and 0.6 kg
OS supported Mac OS X 10.12 or later, Windows 8.1 or later


  • Integrated Thunderbolt 3 cable.
  • Water and fall resistant.
  • A weird design, that captures you.
  • Slow speeds for data transfer.
  • Unsure usability of the integrated cable.

8. OWC Envoy Pro EX – Best Budget Rugged Thunderbolt 3 SSD

While the LaCie Rugged SSD Pro is our top recommendation for photographers and videographers on the move, its high price means it is not ideal for everyone. However, OWC made the perfect alternative with almost the same sustained transfer speeds and robust build quality without breaking the bank.

OWC Envoy Pro EX is an excellent Thunderbolt 3 external SSD for photographers looking to back up their photos and videos without spending a premium. Sure there are some compromises here, but the drive is strong enough to sustain the daily bumps and bruises of the jungle.

The OWC Envoy Pro EX comes in a sleek and robust aluminum enclosure with a rugged, rubberized case that meets military-grade MIL-STD810G drop protection. MIL-STD810G certification requires a device to be dropped over 25 times at every angle from a height of four feet without taking any damage. In addition, the Envoy Pro EX is backed by a 3 Year OWC Limited Warranty to give you an added peace of mind.

Elsewhere, the drive comes with the Thunderbolt 3 cable attached, which is not the best approach, but at least you know there is no chance of losing it. On the other end is an LED light for operating status. It is not the smallest drive you can get at 2.9 x 0.9 x 5.7 inches (WHD), but it is well within the realms of portable drive.

OWC Envoy Pro EX is available in different sizes up to 2TB, excellent for storing and transferring large 4K and 8K videos. It has incredible speeds up to 2800MBps, the same as the LaCie Rugged SSD Pro.
Our Take

If you don’t need dust and water resistance, save your money and get the OWC Envoy Pro EX. It has fast speeds and meets MIL-STD810G standards without breaking the bank. While not water-resistant, this drive can withstand drops, knocks, and extreme temperatures in harsh environments.

  • Robust construction, meeting MIL-STD810G
  • Fast NVMe speeds
  • Attached cable, great for outdoor use and traveling
  • Not dust- or water-resistant

9. Fantom Drives eXtreme – Best Thunderbolt 3 External SSD for Mac

If you want to extend the storage capacity on your Mac, the eXtreme Thunderbolt 3 NVMe SSD from Fantom Drives is one of the best external SSDs you can find in the market. The drive was specifically designed with Mac users in mind, and it comes HFS+ formatted for plug-and-play compatibility on Mac OS 10.13 (High Sierra) or later versions.

The eXtreme SSD features a premium aluminum build with a sleek sandblasted finish. It looks and feels premium, fitting just right into your Mac ecosystem. I would’ve loved it better if the whole drive was space gray instead of the sides only, but it still looks great with the black finish at the top and bottom.

At 2.5 x 4.25 x 0.5 inches, the drive is small and truly portable, fitting into any pocket. The finned design on sides helps in heat dissipation, alleviating thermal issues in sustained heavy loads. Inside, there is a WD Black PCIe NVMe SSD with a thermal pad to ensure reliable performance at all times.

Another great feature with the eXtreme Thunderbolt 3 SSD is that you can easily turn it into a boot drive.

The drive is available in three sizes: 500GB, 1TB, and 2TB. It also comes with an industry-leading 5-year warranty.
Our Take

With the SSD on all the modern MacBooks soldered on the board, upgrading means buying a new Mac. Or you can buy the eXtreme Thunderbolt 3 NVMe SSD from Fantom Drives. This SSD is designed to deliver a flawless and seamless user experience on MacBooks and Mac Mini. With an NVMe drive, the eXtreme external SSD is as fast as your Mac storage.

  • Plug and play on Mac, HFS+ formatted
  • Fast NVMe speeds
  • 5-year warranty
  • Premium build and finish
  • No shockproof or water resistance

10. Sabrent Rocket XTRM Q – High Capacity Thunderbolt 3 External SSD

Technology is evolving, and cameras that can capture 4K or 8K content have become the industry standard, meaning creators are in constant need of high-capacity storage solutions. The Sabrent Rocket XTRM Q is one of the few portable external SSDs supporting high storage capacity of up to 8TB.

Having this much storage in a portable drive is excellent. It gives you the flexibility to capture and transfer large amounts of files, such as many hours of 8K footage, from just about anywhere. You can copy, store, or edit content directly from the external drive.

But the XTRM Q isn’t just about high capacity. With M.2 NVMe drive onboard, you get fast transfer speeds up to 2,700MBps, capable of transferring a large 4K footage in seconds. The speeds are capped at 900MBps when using a USB-C device.

The Sabrent Rocket XTRM Q features full aluminum construction to ensure durability and great heat dissipation. Inside, there is a thermal pad for increased cooling efficiency. The casing is shock-resistant and has anti-slip pads at the bottom to improve stability.

However, some users have reported the XTRM Q might get hot on heavy use, but only if pushing it to the core. We would recommend not gaming directly from the drive.

The drive is available in different sizes, from 500GB to 8TB. It comes with a 2-year warranty valid upon registration on their website.

Our Take

If you’re looking for a fast, portable external SSD with high storage capacity, Sabrent Rocket XTRM Q is the kind of drive you need. With capacities up to 8TB and NVMe speeds of 2,700MBps, the drive is ideal for power users who require more capacity and speed for their workflows. It also comes with a decent cost per GB, delivering more bang for your bucks.

  • High capacity up to 8TB
  • Fast NVMe speeds
  • Supports Thunderbolt 3 (2700MBps) and USB-C (900MBps)
  • Gets hot on heavy writes

Choosing the Best Thunderbolt 3 External Hard Drives and SSDs – The Ultimate Buying Guide

Here’s what to look for in a good Thunderbolt 3 external hard drive for better peace of mind.


Thunderbolt 3 external drives come in two types: solid-state drives and hard disk drives.

Hard Disk Drives (HDDs) have been around for ages. It’s a storage technology that uses spinning disks to read/write data. HDDs are cheaper and available in large capacities up to 14 TB or more. As a result, they are ideal for storing a large number of files such as business data and years of photos and videos.

Suppose you’re looking for the best Thunderbolt 3 external hard drive. In that case, the LaCie Rugged Thunderbolt USB-C (Amazon Link) is the best option for portability, while the G-Technology G-Raid (Amazon Link) excellent for high capacity storage with up to 36TB capacity.

However, with moving parts, HDDs are less reliable and slower in reading and writing data. That’s where Solid State Drives (SSDs) come into play. SSDs have no moving parts. Instead, they use electrical circuitry resulting in faster speeds and high reliability. A typical 512 GB SSD can be up to 20X faster than a midrange HDD (Intel).

The benefits of SSDs manifest in many ways, such as faster boot times, quicker data transfer rates, and reduced loading screens. The incredible speeds of SSDs make them ideal for high-bandwidth workflows, such as 4k and 8k video editing and transferring large files.

If you don’t want to sit and wait hours to copy a single file, you need an SSD. Also, SSDs are not susceptible to mechanical damage with no moving parts and can withstand extreme shock, vibrations, and temperatures, and more. If you need peace of mind, an external SSD is highly recommended.

Samsung Portable SSD X5 (Amazon Link) is the best Thunderbolt 3 external SSD in the market, with speeds up to 2800MBps. If you need the speed of SSDs and high storage capacity of HDDs, the Seagate Firecuda Gaming Dock (Amazon Link) with an HDD onboard and M.2 slot for NVMe SSDs delivers the best of both worlds.

Interface: USB-C is not Thunderbolt 3

While USB-C and Thunderbolt 3 use the same connector, the two technologies aren’t the same. Thunderbolt 3 supports 40Gbps while USB-C maxes out at 10Gbps, depending on the USB specification used.

A Thunderbolt 3 SSD may still work on a USB-C laptop but at reduced speeds. You cannot get the best of a Thunderbolt 3 SSD on a USB-C host, which is a bummer since, with SSDs, you’re literally paying more for speeds.

For instance, the Sabrent Rocket XTRM Q (Amazon Link) supports up to 2,700MBps through Thunderbolt 3 and only 9,00MBps when connected to a USB-C PC. Even worse, some SSDs such as the Plugable Thunderbolt 3 External SSD NVMe Drive (Amazon Link) require a Thunderbolt 3 host and don’t work via USB-C.

It is good the check the capabilities of your system before investing in a Thunderbolt 3 external SSD or HDD. If your PC does not support Thunderbolt 3, save your money and get the best USB-C external SSD you can afford.

Thunderbolt 3 Ports

Manufacturers continue to strip away most of the ports in the latest laptops in favor of thin and lightweight design. Having a second Thunderbolt 3 port on an external drive allows you to connect multiple other devices through a single port.

With this, you can use a single Thunderbolt 3 port on your laptop for the drive and also other multiple devices via daisy-chaining. However, you need a Thunderbolt 3 external SSD or HDD with more than one Thunderbolt 3 port. The Seagate Firecuda Gaming Dock (Amazon Link) offers just that, including a few more ports.

Storage Capacity

How much storage capacity you need depends on you. Generally, we recommend starting with 500GB for transferring files, photos, and other media. If you want to store more files for long, including large video files, you’ll be better off with a 1TB or more.

256GB is too small for an external drive and is only recommended for internal use as a boot drive.

Most consumer Thunderbolt 3 SSDs are available up to 4TB, but some, like the Sabrent Rocket XTRM Q (Amazon Link), offer high capacities of up to 8TB. You can get even higher storage capacity if you go with an external HDD instead.

The best thing is that drives become cost-effective as you go up in size. A 2TB drive has a low cost per GB than a 500GB drive. Therefore, if you’re planning to add more storage in the future, you’re better off buying a single high-capacity drive than multiple small ones.

Transfer Speeds

Generally, SSDs are faster than HDDs. Even better, when the external drive has an M.2 NVMe SSD inside. NVMe drives are the fastest SSDs in the market, great for copying large files and portability.

Even so, you’ll need a Thunderbolt 3 PC to take advantage of the fast NVMe speeds. No matter how fast an external drive is, the speed will be capped at 1050MBps (or lower) with a USB 3.2 interface and 480MBps with USB 3.0. Thunderbolt 3 allows fast transfer speeds on external drives such as 2,800MBps on the Samsung Portable SSD X5 (Amazon Link).

Therefore, while external SSDs are fast, the speed is determined mainly by the host interface on your system.

If you want the best gaming performance off an external drive, faster content creation, and quick transfer speeds, ensure to pair an external NVMe drive with a Thunderbolt 3 (USB4/Thunderbolt 4) capable system.

Size and Weight

The best Thunderbolt 3 external SSD/HDD is small and compact. If you want an external drive for use when out and about, ensure it is portable enough to stuff it in a bag or tuck it in your pocket. With this, you can access and transfer files from just about anywhere.

Fortunately, most external SSDs come in small sizes, ideal for portability. Except for the Seagate Firecuda Gaming Dock and G-Technology G-Raid, all the other external drives in this post are compact and portable.

At 4.0 by 1.9 by 0.6 inches, MyDigitalSSD Pocket Vault Express (Amazon Link) is the most portable Thunderbolt 3 external drive you can buy. However, if you need fast speeds, Samsung X5 remains the best option.

Durability & Toughness

While most external drives are built with portability in mind, some are designed to endure extreme weather conditions and environments. If you’re a photographer or videographer always navigating rocky terrains and spending most of the time in the jungle, you need an SSD with robust and uncompromising build quality.

Some drives come with a rugged case that can withstand shock, drops, and extreme temperatures.
