How We Tested These SSDs
Unlike many buying guides that simply repeat manufacturers’ specifications, we’ve focused on how these SSDs actually perform with macOS.
Every drive in this guide has either been tested by us or evaluated using extensive real-world performance data from trusted Mac-focused sources. Rather than relying solely on synthetic benchmarks, we looked at how each SSD performs during everyday tasks that matter to Mac users.
Our testing criteria included:
- Real-world file transfer speeds using large photo and video libraries.
- Sustained write performance during long transfers, where many SSDs begin to slow down.
- Compatibility with Apple Silicon Macs running recent versions of macOS.
- Performance when used for Time Machine backups and external boot drives.
- Thermal management and whether the drive throttles under heavy workloads.
- Build quality, portability and durability.

Do You Really Need a Thunderbolt SSD?
One of the biggest misconceptions when buying an external SSD for a Mac is that you need a Thunderbolt drive to get good performance.
In reality, most Mac users will see very little difference between a quality USB-C SSD and a much more expensive Thunderbolt model for everyday tasks such as:
- Time Machine backups
- Storing photo libraries
- Managing documents
- Running music or video collections
- Editing occasional 4K video
A good USB 3.2 Gen 2 SSD already delivers transfer speeds of around 1,000 MB/s, which is more than fast enough for most workloads.
Thunderbolt SSDs come into their own when you’re regularly:
- Editing multiple streams of ProRes or 8K video.
- Working with very large RAW photo libraries.
- Running virtual machines.
- Using an external SSD as your primary startup disk.
- Copying hundreds of gigabytes of data every day.
If that sounds like the way you work, a Thunderbolt SSD is a worthwhile investment. Otherwise, you’ll usually get much better value from a USB-C model.

External SSD Buying Guide
Choosing an SSD isn’t simply about buying the fastest drive. For most Mac users, reliability, compatibility and value are far more important than benchmark numbers.
Here’s what to look for before you buy.
USB-C vs Thunderbolt SSDs
One of the most common mistakes people make is assuming they need a Thunderbolt SSD because their Mac has Thunderbolt ports.
In reality, most Mac owners will be perfectly happy with a USB-C SSD.
A quality USB 3.2 Gen 2 SSD already delivers real-world speeds of around 1,000 MB/s, which is fast enough for:
- Time Machine backups
- Storing Photos libraries
- Editing 4K video
- Running apps from an external drive
- Large file transfers
- Everyday creative work
Thunderbolt SSDs are considerably faster, but you’ll usually only notice the difference if you regularly:
- Edit multiple streams of 4K or 8K ProRes footage.
- Transfer hundreds of gigabytes every day.
- Work directly from large Final Cut Pro or DaVinci Resolve projects.
- Use your external SSD as your main startup drive.
For everyone else, you’ll often get better value by spending the difference on a larger-capacity USB SSD.
For more on this, check out our guide to Thunderbolt vs USB-C.
Why Macs Don’t Benefit Fully From USB 3.2 Gen 2×2
If you’ve been shopping around, you’ve probably noticed SSDs advertising speeds of 2,000 MB/s over USB.
Unfortunately, most Macs can’t achieve these speeds.
That’s because Apple has never added native support for the USB 3.2 Gen 2×2 standard. As a result, drives such as the Samsung T9 typically perform at around 1,000 – 1,200 MB/s on macOS instead of their advertised maximum speed.
This doesn’t make these drives a poor choice – they’re still among the fastest USB SSDs available—but it’s worth knowing that you won’t see their full performance unless you also use them with compatible Windows PCs.
If maximum speed is your priority on a Mac, Thunderbolt remains the better option.
How Much Storage Do You Need?
Buying the right capacity is almost as important as choosing the right SSD. Here’s a rough idea of what you may need although these can vary wildly from person to person.
| Capacity | Best for |
|---|---|
| 500GB | Documents, backups and everyday use |
| 1TB | Most Mac users ⭐ |
| 2TB | Photography, gaming and video editing |
| 4TB+ | Professional media libraries |
SSD vs External Hard Drive
If you’re upgrading from an older external hard drive, you’ll notice a dramatic improvement by switching to an SSD.
| External SSD | External HDD |
|---|---|
| Extremely fast file transfers | Much slower read/write speeds |
| Silent operation | Mechanical noise |
| No moving parts | More vulnerable to knocks and drops |
| Compact and lightweight | Usually larger and heavier |
| More expensive per GB | Cheaper for very large capacities |
Traditional hard drives still make sense if you simply need enormous amounts of storage for archiving, but for almost every everyday Mac task, we’d recommend an SSD.
Are SSDs Good for Time Machine?
Yes. SSDs make Time Machine backups much faster than traditional hard drives and are quieter and more reliable. We recommend choosing a drive that’s at least twice the size of your Mac’s internal storage. The Samsung T7 Shield remains our favourite for Time Machine thanks to its speed and reliability.
Can You Boot macOS From an External SSD?
Yes, you can easily create a boot drive from an external SSD.
Modern Macs allow you to install and boot macOS from an external SSD, making it a useful option if your internal storage is running out of space, your Mac is running slow, or you want to test beta versions of macOS.
USB SSDs work well for everyday use, while Thunderbolt SSDs provide an experience that’s much closer to using your Mac’s internal storage.
If you’re planning to run macOS externally every day, we’d recommend investing in a Thunderbolt SSD such as the SanDisk Professional PRO-G40 or OWC Envoy Pro TB5.
How to Format an External SSD for Mac
Most new SSDs arrive formatted as exFAT, allowing them to work with both Windows PCs and Macs.
If you’ll only use the drive with your Mac, however, it’s usually worth reformatting it as APFS, which offers better performance and supports features such as snapshots, encryption and Time Machine.
Here’s a quick guide:
- APFS – Best for Macs only and required for Time Machine on modern versions of macOS.
- exFAT – Best if you’ll regularly switch between Mac and Windows.
- Mac OS Extended (HFS+) – Only recommended for older Macs running legacy versions of macOS.
Formatting takes only a few minutes using Disk Utility, but remember that it erases everything on the drive, so make sure you’ve backed up any important files first.
For more, check out our guide on how to to format an external drive for a Mac.
How Long Do External SSDs Last?
A quality external SSD should last between five and ten years, and in many cases even longer. Unlike traditional hard drives, SSDs have no moving parts, making them much more resistant to knocks, drops and everyday wear.
However, SSDs don’t last forever. Every memory cell has a limited number of times it can be written to before it begins to wear out. Manufacturers measure this using a rating known as TBW (Terabytes Written), which indicates the total amount of data that can typically be written to the drive during its lifetime.
For example, a 1TB SSD might be rated for around 600TBW. To put that into perspective, you’d need to write around 160GB of data every single day for 10 years to reach that limit. For most Mac users, whether you’re backing up with Time Machine, storing photos or editing occasional videos, it’s unlikely you’ll ever come close.
There are also a few simple ways to maximise the lifespan of your SSD:
- Leave 10–20% of the drive free. SSDs perform best when they have spare space available for wear levelling and background maintenance.
- Keep the firmware up to date. Manufacturers such as Samsung, Crucial and SanDisk occasionally release firmware updates that improve performance, stability and reliability. These can usually be installed using the manufacturer’s utility software.
- Avoid excessive heat. Although portable SSDs are designed to withstand heavy use, prolonged high temperatures can reduce performance and, over many years, may shorten their lifespan. If you’re regularly transferring very large files, allow the drive to cool between extended workloads.
- Choose a reputable brand. Established manufacturers typically use higher-quality flash memory, better controllers and provide longer warranties than cheaper, unbranded alternatives. Spending a little more on a trusted SSD often pays off in better reliability and longer-term support.
For most Mac owners, an external SSD will become obsolete long before it wears out. As long as you choose a quality drive and keep regular backups of important files, you can reasonably expect it to provide many years of fast, dependable storage.
Conclusion
While there are faster external SSDs available than ever before, most Mac users don’t need to spend premium prices to get excellent performance.
Whether you choose an affordable USB-C SSD or invest in Thunderbolt 5, every drive in this guide offers a substantial upgrade over a traditional hard drive. For most Mac owners, a quality USB-C SSD provides the best balance of speed, reliability and value, while professionals working with demanding creative projects will benefit from Thunderbolt’s additional performance.
For the majority of people, the Samsung T7 Shield remains the best external SSD for Mac thanks to its combination of speed, reliability, durability and value. It’s fast enough for Time Machine, photo libraries, 4K video editing and everyday file transfers, making it the easiest recommendation for most Mac owners.
If you’re shopping on a tighter budget, the Crucial X9 Pro offers very similar real-world performance for less money. Meanwhile, creative professionals working on demanding video projects should consider investing in a Thunderbolt SSD such as the SanDisk Professional PRO-G40 or OWC Envoy Pro TB5, both of which offer substantially higher transfer speeds for compatible Macs.
Ultimately, the best SSD is the one that matches the way you use your Mac rather than the one with the highest benchmark score. By choosing the right balance of capacity, connection type and performance, you’ll end up with fast, reliable storage that should last for years.
