Best SSD External: Comparison

Samsung T7 Touch SSD Review

Editor’s Choice

The Samsung T7 Touch is compact enough to always be at hand. It also has excellent speed performance - up to 1050 MB/s for reading data and up to 1000 MB/s for writing. The main feature of the model is a built-in fingerprint scanner. This allows, on the one hand, to protect information using AES hardware encryption, and on the other hand — to unlock access to data with a simple touch, without entering passwords or additional software installation. Initial configuration is performed in the Samsung Portable SSD utility. Four fingerprints in total can be used. The frame of the biometric sensor acts as a status indicator light.

Samsung T7 Touch with NVMe interface features 96-layer TLC 3D V-NAND memory, and maximum speed is achieved through SLC caching technology. The terabyte version has a SLC buffer size of about 42 GB, and once it's full, the write speed drops to about 350 MB/s. If you often have to work with large files, it is worth considering this point. Two cables are included for connecting to the devices with a full-sized USB connector or USB Type-C. The rugged metal enclosure is drop-proof up to 6 feet high and helps dissipate heat under load. There is also a Samsung T7 version without a fingerprint sensor. It has the same dimensions and speeds but costs a little bit less.

Summary: As indicated by my tests the Samsung T7 Touch is a compact, high-speed SSD with read/write speeds up to 1050/1000 MB/s. Its standout feature is a built-in fingerprint scanner for secure, password-free access via AES hardware encryption, supporting up to four fingerprints.

The device is gripable and doesn't slip in your hand, but the surface of the case collects fine debris and dust. The manufacturer added a full-size USB adapter to the short cable with USB Type-C on both ends.

Summary: After trying out this product, I can say that  the SanDisk Extreme Portable SSD V2 is rugged and fast, offering 1050 MB/s speeds and AES 256-bit encryption. Built for harsh conditions, it features IP55 protection, resists drops up to 2 meters, and operates in extreme temperatures. Compact and lightweight, it’s ideal for backups and 4K video processing, with a loop for easy attachment and versatile USB connectivity.

ADATA SC685 SSD Review

Best Budget

This is one of the most affordable portable SSDs in terms of cost per gigabyte. ADATA SC685 shows good speeds in tests, close to the claimed 530 MB/s for reading and 460 MB/s for writing, although in random access operations it lags behind more expensive models.

The SSD will be several times faster than the hard drive anyway. The bandwidth is also enough to work with the next-generation PlayStation 5 and Xbox Series X/S consoles (you can store your library on an external device so you don't lose time downloading games over the Internet every time).

The ADATA SC685 is slightly larger than the Samsung T5 and weighs only 35 grams. The case is completely plastic, with an LED indicator near the USB Type-C port. A pretty good option for those who aren't chasing top-of-the-line performance.

Summary: The ADATA SC685 is an affordable portable SSD offering good value for its cost per gigabyte. With read/write speeds of 530 MB/s and 460 MB/s, it performs well, though it lags in random access compared to pricier models. Compact and lightweight at 35 grams, it’s ideal for storing game libraries for PS5 and Xbox Series X/S, saving time on downloads. Its plastic build includes a USB Type-C port with an LED indicator, making it a solid choice for users seeking affordability over top-tier performance.

Western Digital My Passport SSD Review

Best Smart Design

In WD My Passport the manufacturer refused from sharp edges. The case is now smooth and the textured wave pattern on the top metal cover provide a more comfortable grip. WD Blue SN550E NVMe SSD is used inside. Apparently, we're talking about a modification of the SN550 M.2 storage, which has a high write endurance (600 TB for the 1 TB model). Maximum data reading speed is 1050 MB/s, and writing — 1000 MB/s (in terabyte version it drops to 710 MB/s after the first 12 GB due to SLC cache filling).

The SSDs support AES-256 hardware encryption. Although there is no fingerprint scanner here, like with the Samsung T7 Touch, the WD Security utility allows you to enable automatic unlocking on the user's primary computer. While most external SSDs come with a three-year warranty, the WD My Passport has extended the warranty to 5 years, with no write limitations. The package includes a 15-cm USB Type-C cable and an adapter to USB Type-A.

Summary: The WD My Passport offers up to 1050 MB/s read and 1000 MB/s write speeds, with durable WD Blue SN550E NVMe SSD inside. It features AES-256 encryption, a sleek design, and an industry-leading 5-year warranty, plus USB Type-C and Type-A compatibility, making it a reliable and versatile storage option.

Transcend 855 JetDrive SSD Review

Best SSD for Mac

Transcend has offered an interesting 2-in-1 solution: the JetDrive 855 is a fast external Thunderbolt drive, while the internal NVMe SSD JetDrive 850 is suitable for Mac storage upgrades. The package includes the necessary screwdrivers. For a start, it's worth checking the list of compatible Apple devices on the manufacturer's website. There's no need to rush to get rid of the old SSD drive, either — you can insert it into the free JetDrive case and use it for a new purpose.

Transcend's JetDrive 855 employs four PCI Express lines instead of two as its predecessor. As a result, read/write speeds have increased one and a half times to 1600/1400 MB/s. As the drive is initially aimed at Mac users, the company says nothing about compatibility with other platforms. However, it can work with Windows laptops equipped with a Thunderbolt port ("regular" USB Type-C won't do). 

Summary: The Transcend JetDrive 855 is a versatile 2-in-1 solution, combining a fast Thunderbolt external drive with an internal NVMe SSD (JetDrive 850) for Mac storage upgrades. It includes necessary tools and allows repurposing old SSDs using its provided case. With PCIe 4-lane technology, it achieves speeds of 1600/1400 MB/s, making it 1.5 times faster than its predecessor. Primarily designed for Mac users, it also supports Windows laptops with Thunderbolt ports, offering excellent performance for compatible devices.

FAQ about Best External Portable SSD

Common questions about the best external portable SSD, answered!

Why do I need an external SSD?

A portable drive can be used to back up important information or to offload your primary drive. Today's devices provide enough speed to process photos and edit content immediately on an external SSD. From the Samsung T7 Touch to the WD My Passport SSD, all models in my ranking are small and lightweight, so you can always carry them with you.

What's the difference between an SSD and a regular hard drive?

A hard drive is a device with spinning platters that store information and read/write heads. It takes time for the hard drive to position the heads and then you have to wait for the proper sector to appear on the drive. All this is accompanied by a whirring and clicking noise. If the files consist of many fragments scattered all over the drive, the reading is even slower. HDDs (from Hard Disk Drive) have a higher risk of damage from bumps and drops due to the way they work, although modern models are better protected against mechanical impacts.

SSD (Solid State Drive) has no moving parts and therefore read and write requests are processed much faster. SSDs are nearly silent, smaller and lighter than hard drives.

What's the most reliable external drive?

Any SSD from the table will serve its owner for years to come, but the WD My Passport SSD and SanDisk Extreme Portable SSD V2 have a potentially longer lifespan (they have virtually the same internal hardware). Plus, both models come with a five-year warranty versus three years for the major competitors.

Can I make partitions on an SSD?

There is no difference in this regard between SSDs and HDDs, internal or external drives. Logical partitions on the disk allow you to separate the operating system from the rest of your data, and in Windows and macOS they can be created using built-in tools without any third-party software download.

Do I need to leave free space on the SSD?

It is not absolutely necessary, because each SSD has a reserve of cells. But experts recommend leaving 10-15% free space, because when the drive gets full, its performance gets reduced.

What can I install on my SSD?

You can install applications, games, and even an operating system on the external drive. Some programs store some data on the system disk, and therefore will not work when you connect the SSD to another device. This is where Portable versions, which run without installation, can come in handy.

The SSD allows you to speed up the launch of games on consoles of the previous generation. With PlayStation 5 and Xbox Series X everything is a little more complicated: with SSD you can play only older games. For new projects it is only allowed to backup to external media (PS5 does not yet support the function, but it will be added in future updates).

How long can I keep information on my SSD?

Your data can be kept for decades, but the memory cells will lose charge if you don't power them for a long time. A safe downtime period for data retention in consumer models is between a year and a few years. But why push your luck? If the SSD has been on the shelf for half a year, it is advisable to connect it to your computer and read the entire memory array (for example, by making a backup, and in Linux systems it is sufficient to read the drive into /dev/null).

In any case, don't keep all your important information in one place. SSDs are imperfect and sometimes they fail before the warranty expires.
