SSDs (Solid State Drives) used to be the most expensive hard drives on the market and while they’re still more expensive than mechanical HDDs, they’re a lot cheaper than they used to be.
The SATA internal hard drives in all new Macs use SSD technology because unlike mechanical drives, SSDs have no moving parts meaning they’re far faster, quieter, more efficient and durable.
This is because instead of using spinning platters to save data like HDDs, SSDs use NAND memory chips instead.
This also makes them much faster as the average SSD can write at up to 1050MB/s, although real-life speeds are usually a touch below this.
This is almost 10 times faster than external mechanical HDD drives that write at around 115MB/s.
The best Thunderbolt external drives work even faster than this with speeds of over 3000MB/s possible with Thunderbolt 4 and even 6000MB/s with the latest Thunderbolt 5 drives.
Apart from speed, SSDs are much smaller, lighter and more portable than HDDs.
But which one should you go for? Which SSDs work best with macOS? Which ones work best with Apple Silicon Macs?
Here we’ve done the hard work for you and reviewed the best external SSDs for Mac of 2025.

1. SanDisk Professional Pro-G40 SSD
The SanDisk Professional Pro-G40 SSD came out top in our tests thanks to its blistering Thunderbolt driven speed and incredible lightweight portability.
Although Thunderbolt SSDs are always a bit more expensive, the SanDisk Pro G40 doesn’t cost much more than the other SSDs and is definitely good value for the incredible transfer speeds it offers.
Because it’s able to fully utilize Thunderbolt 3 and 4 ports on Macs, you can enjoy read-write transfer speeds of at least 2500MB/s which is more than twice as fast as most non-Thunderbolt SSDs featured here.
We found that it achieved Write speeds of 2640 MB/s and Read speeds of 2747 MB/s via Thunderbolt 4 on an M3 MacBook Pro which is pretty outstanding.
With these speeds, its firmly aimed at creative users such as video editors and graphic designers that transfer several GB of data regularly.
In our testing, it managed to transfer 20GB of data from our Mac in just 1 minute and 39 seconds as you can see here.
The SanDisk Professional Pro-G40 SSD is surprisingly durable too with an IP68 rating for water resistance and drop resistant up to 3 meters according to SanDisk.
It’s available in 1TB, 2TB and 4TB versions with the biggest version costing around $499.99.
The SanDisk Pro G40 also offers an excellent alternative to the much more expensive Samsung X5 which used to the best Thunderbolt drive out there but is now discontinued.

When we first tested the Orico K20, we didn’t know what to expect but what we discovered was an excellent value SSD drive that magnetically sticks to your Mac or iPhone.
For those that want a storage solution that you can switch between macOS and iOS, the Orico K20 is about as convenient and portable as it gets.
It’s almost half the size of any external hard drive we’ve tested, easily fitting into the palm of your hand.
Its standout feature is the magnetic base, allowing it to securely attach to metal surfaces like the back of a laptop or the edge of a desk.
It connects to your Mac’s thunderbolt port via a short USB-C cable.
It’s available in storage capacities ranging from 512GB to 2TB and uses USB 3.2 Gen 2 for fast data transfer speeds of around 900MB/s in our tests.
There’s no additional software to install and it’s ideal for those looking for a cost effective, fuss-free, high-speed external storage solution.
Check out our full Orico K20 review for more.
Pros:
- Magnetically attaches to Macs and iPhones
- Very small
- Fast transfer speeds of around 900MB/s
- Slick design
Cons:
- Very short cable
- No IP rating for dust and water resistance
4. Samsung T9 Portable SSD
If you don’t have the budget for a Thunderbolt SSD then the Samsung T9 Portable SSD is the next best thing thanks to fast USB 3.2 Gen 2.2 read-write speeds, portability and reliability.
The Samsung T9 is incredibly small at just 3.46 x 2.36 x 0.55 inches and weighs just 4.3 ounces so it’s small enough to take anywhere.
Although it’s capable of up to read/write speeds of 2000MB/s, it doesn’t support Thunderbolt so Mac Mac users will only get speeds of around half this for reasons explained here.
The Samsung T9 Portable has a shock cover although it’s not marketed as shock resistant and if this is important to you, check out Samsung’s T7 shield portable below.
One clever feature of the T9 is that if it detects that the drive is getting too hot, it slows down transfer to reduce the risk of damage to the drive and preserve the lifetime of it.
You can also format the Samsung T9 in multiple formats and partitions so for example, you could have half the drive formatted in APFS and the other half in exFAT.
The only downside is the Samsung software that comes with it which you don’t have to use but is supposed to help you manage the disk more easily but Samsung are often slow to update it for new versions of macOS.
If you’re looking for incredibly fast transfer speeds, the latest in SSD technology, portability and durability, the Samsung T9 is the best Mac SSD for all round performance and value for money.
Pros:
- Best non-Thunderbolt SSD
- 1TB, 2TB and 4TB available
- Allows you to partition the drive
- Manages heat to prevent damage to the drive
- Compact
- Reliable
Cons:
- Samsung drive software can be unstable on Macs
5. Samsung T7 Shield Portable (44% off)
The Samsung T7 Shield Portable (note that there is no T9 Shield Portable) is a tougher, more rugged version of the older Samsung T7 Portable (which is basically a slower version of the T9) with a stronger rubber sleeve for outdoor use.
It’s a bit cheaper than the standard Samsung T7 Portable and is a better option if you’re going to be on the move a lot, particularly outdoors such as doing photography or filming video.
Samsung claim that the T7 Portable can withstand being dropped from a height of 3 meters and it is IP65 rated for dust and water resistance.
It’s available in 1TB, 2TB and 4TB versions and like the standard version, can be used with the Samsung Portable SSD app to password protect and encrypt the drive.
It has a USB-C port and cable but also includes a USB-A adapter for connecting to older Macs.
The dimensions of the Samsung T7 Shield Portable are slightly bigger than the standard T7 model but it still fits into a coat pocket or backpack easily.
With a USB-C connection connected to your Mac, you should get read-write speeds above 1000MB/s with the Samsung T7 Shield Portable which makes transferring files back and forth extremely quick.
You can currently get 44% off the 2TB version too making it a steal for an SSD drive this durable.
Pros:
- Extremely durable
- Water and dust resistant
- Drop resistant up to 3 meters
- The most portable SSD drive we’ve seen
- Available in 1TB, 2TB and 4TB
- USB-A connection for older Macs too
Cons:
- Samsung drive software can be unstable on Macs
6. VectoTech Rapid 8TB External SSD
While most external SSDs have a maximum of 4TB space, the VectoTech Rapid External SSD offers an 8TB model for those that need extra storage space.
It has a USB-C port although because it only supports USB 3.2 Gen 2, the maximum transfer speed is a bit slow at 540MB/s for an SSD but if this is not an issue for you, the extra storage space is a huge plus.
The other big plus is that VectoTech’s SSD doesn’t require an external power supply as it’s powered by the USB-C port.
The aluminum casing is surprisingly durable with drop resistance up to around 1.8 meters (6 feet) and doesn’t get hot to the touch.
Like most SSDs, it’s also incredibly quiet with no moving parts inside like you get with HDDs.
Finally the drive works out of the box with Macs as it’s formatted in exFAT format so you can start transferring files or use Time Machine to back-up immediately.
Pros:
- 8TB of storage available
- No external power supply needed
- Durable and reliable performance
Cons:
- Relatively slow transfer speed for an SSD
- Price
7. WD My Passport For Mac SSD Portable
WD are one of the biggest brands in the external hard drive market and it’s no surprise the WD My Passport SSD Portable is one of the best SSD external drives specifically for Mac.
The WD My Passport For Mac SSD is the solid state drive version of the incredibly popular WD My Passport For Mac HDD which is the slower mechanical version of this drive.
One thing we like about WD is that they work straight out of the box with Macs so there’s no need to format them first. Just plug it in and Time Machine will start backing-up right away
WD claim the drive is capable of read speeds of up to 1050MB/s and write speeds of 1000MB/s although in reality, you’ll get a little under this when using it with a Mac via USB-C.
The drive is also drop resistant up to 6.5ft (1.98m) and is cross compatible with USB 3.2 Gen-2 and USB-C (USB-A for older ports).
It also has a USB Micro-B port and comes with two cables: USB-A to USB Micro-B and USB-C to USB Micro-B.
Since Macs have Thunderbolt-3 which uses a type-C port, it works perfectly well with Macs although you won’t quite the speeds of a dedicated Thunderbolt connection.
If you want a reliable, fast and durable drive that works out of the box with Macs, the WD My Passport SSD is one of the best SSDs you can get.
Pros:
- Reliable
- AES-256 encryption
- 3 year warranty
- Up to 4TB storage capacity
Cons:
- WD backup software

Thunderbolt vs USB-C
If speed is your main concern, we strongly recommend going with an SSD that supports Thunderbolt.
If you use a Thunderbolt compatible SSD, you”ll get speeds of up to 2500Mb/s which is twice as fast as most USB-C SSDs are capable of.
The reason is because most SSDs only support USB 3.2 Gen 2 connections which Macs can’t fully utilize.
The result of this is that although many SSDs are advertised as achieving read/write speeds of up to 1050MB/s (or even 2000 MB/s with USB Gen 2.2 connections), Macs can only use half of this.
Bear in mind though that drives that support Thunderbolt are more expensive.
For more on this, check out our guide the best Thunderbolt drives for Mac.
Formatting SSDs For Macs
Most SSDs come pre-formatted and ready for use with Macs, but some are set up exclusively for Windows.
Starting with macOS High Sierra, Apple transitioned from the older HFS+ format to the Apple File System (APFS), which is compatible across both macOS and iOS devices.
While external drives formatted in HFS+ are still supported by the latest macOS versions, using APFS offers enhanced security and better integration with iOS devices. If your SSD will only be used with a Mac, iPad, or iPhone, either HFS+ or APFS will work well.
However, if you need to transfer files between a Windows PC and a Mac, you’ll need to format the drive using the exFAT file system, as neither HFS+ nor APFS is compatible with Windows.
You can find out more about how to do this in our look at how to reformat external drives for Macs.
External SSD Downsides
- Cost: The main disadvantage of SSDs vs standard HDDs is the price as you pay more for less storage space. SSDs are usually at least twice as expensive as mechanical drives. For example, whereas the mechanical WD My Passport For Mac HDD 5TB drive costs just over $100, the WD MyPassport 2TB SSD Drive costs almost $300 for less than half the capacity. If you buy one with a Thunderbolt connection, then they cost even more.
- Capacity: External SSDs also have less capacity and usually only go up to a maximum of around 4TB whereas you can find external HDDs of 18TB or even more.However, there are some drives such as the VectoTech Rapid External SSD that go up to 8TB.
- Lifespan: In terms of durability, although SSDs are far more durable and last longer than mechanical HDD drives, the memory cells in SSDs eventually age and die although you should get at least 5 years of usage out of one and probably much more. This is because Solid State Disks have a maximum number of writes or “endurance” which is referred to as TBW (terabytes written) and is typically 65 to 150 TBW.
