In my line of work, data is everything. It’s raw 4K video footage from a weekend shoot, a massive Lightroom catalog containing years of photography, and gigabytes of project files that need to move between my desktop workstation and my travel laptop. For years, I relied on a collection of spinning portable hard drives. I remember the anxiety vividly: the gentle whirring that was a constant reminder of their mechanical fragility, the agonizingly slow transfer progress bars, and the sheer bulk of carrying multiple drives. Moving a 100GB project folder felt like an overnight task, a workflow bottleneck that stifled creativity and wasted precious time. The fear of a single drop rendering hours of work inaccessible was a constant, low-level hum of stress. This is the modern creator’s curse: our digital lives are expanding exponentially, but our patience for slow technology is shrinking just as fast. We need a solution that is not just big, but fast, durable, and, above all, effortlessly portable.

What to Consider Before Buying an External Solid State Drive
An External Solid State Drive (SSD) is more than just an item; it’s a key solution for liberating your digital life from the constraints of your device’s internal storage. Unlike traditional hard disk drives (HDDs) that use spinning platters and a mechanical arm, SSDs use flash memory, similar to a USB stick but vastly more powerful and reliable. This fundamental difference means they are exponentially faster, more resistant to drops and shocks, silent, and significantly smaller. The main benefits are a dramatic reduction in file transfer times, the ability to run applications or even entire operating systems directly from the drive, and the peace of mind that comes with a more durable storage medium. For professionals, gamers, and everyday users, this translates to a smoother, faster, and more efficient workflow.
The ideal customer for this type of product is someone facing a storage or speed bottleneck. This includes content creators (videographers, photographers, musicians) who work with large files, gamers looking to expand their console or PC library without sacrificing load times, and professionals who need to transport large datasets securely. It’s also perfect for the meticulous user who wants a fast and reliable backup for their precious memories and documents. However, a portable SSD might be overkill for those who only need to transfer small documents or a handful of photos occasionally. For them, a simple USB flash drive would be more cost-effective. Likewise, for archival, long-term cold storage where speed is not a factor, a larger, cheaper traditional external HDD might still make sense.
Before investing, consider these crucial points in detail:
- Dimensions & Space: Portability is a primary reason to buy an external SSD. Consider the physical footprint. The best drives, like the Lexar ES3 1TB Portable SSD, are often smaller than a credit card and only a centimeter thick. This allows them to slip into a pocket, a small pouch in a laptop bag, or even a wallet, making your data truly accessible anywhere without adding bulk or weight to your everyday carry.
- Capacity/Performance: Don’t just look at the gigabytes; look at the gigabits per second. The interface is key. A USB 3.2 Gen 2 port, offering speeds around 10Gbps (approx. 1050 MB/s), is the sweet spot for most users, providing blazing-fast transfers. Ensure both the drive and your computer support this standard to avoid bottlenecks. For capacity, 1TB is a versatile starting point for most users, balancing cost and space effectively.
- Materials & Durability: Since these devices are meant to travel, durability is non-negotiable. Look for enclosures made of metal or high-quality, reinforced plastics. While many drives offer some level of shock resistance due to their solid-state nature, a sturdy exterior provides an extra layer of protection against the inevitable bumps and scrapes of daily use. Some users noted the Lexar ES3 has a plastic shell designed to look like metal, which keeps it light but might be a consideration for those demanding premium materials.
- Ease of Use & Maintenance: The best technology is invisible. A great portable SSD should be plug-and-play, requiring no complex driver installations. It should be recognized instantly by a wide range of operating systems like Windows, macOS, and Linux. Look for drives that come pre-formatted with a compatible file system (like exFAT) for cross-platform use out of the box, simplifying your workflow from the very first connection.
Choosing the right drive is about matching these features to your specific needs and budget.

Deep Dive: Putting the Lexar ES3 Through Its Paces
A portable SSD lives or dies by its performance in the real world. Specifications on a box are one thing, but how a drive handles the demands of large file transfers, content creation workflows, and gaming is what truly matters. We spent weeks integrating the Lexar ES3 1TB Portable SSD into our daily routine, testing its speed, portability, and versatility across a range of devices and scenarios to see if it delivers on its promises.
Design and Ultimate Portability
The standout feature of the Lexar ES3 1TB Portable SSD is, without a doubt, its incredible portability. Lexar claims it’s smaller than a standard card, and they aren’t exaggerating by much. This drive is so small and light that it fundamentally changes how you think about carrying a terabyte of data. It disappears into a jeans pocket or the pen slot of a laptop bag. This was a sentiment echoed by numerous users, with one noting, “It is small, and I mean really small, which makes it really portable, which is a good thing.” During our testing, this became its greatest strength. We took it on location for a photo shoot, and instead of lugging a bulky hard drive case, we simply slipped the ES3 into a pocket. The ability to quickly offload SD cards in the field without adding any meaningful weight to our gear was liberating. The drive’s shell, while plastic, has a graphite-like texture that resists fingerprints and feels secure in hand. The minimalist aesthetic is professional and unassuming, fitting in anywhere from a coffee shop to a corporate boardroom. While some might prefer the cold, hard feel of aluminum, we found the lightweight plastic construction to be a practical advantage, contributing to its featherlight 45-gram weight and ensuring it won’t scratch a laptop or tablet it’s tossed in a bag with. For anyone whose work or hobbies require them to be mobile, this design is a near-perfect balance of form and function. You can see its slim profile and design up close here.
Real-World Speed and Performance Testing
Lexar advertises impressive speeds of up to 1050 MB/s read and 1000 MB/s write, figures that place the ES3 squarely in the high-performance tier of USB 3.2 Gen 2 drives. To verify these claims, we connected it to a MacBook Pro with a Thunderbolt 4 port and a Windows PC with a dedicated USB 3.2 Gen 2 port. Using benchmark tools like Blackmagic Disk Speed Test, we consistently achieved results that were very close to the advertised specs, clocking in at around 980 MB/s read and 920 MB/s write. These are fantastic numbers that translate into tangible real-world benefits. We transferred a 50GB folder of mixed media files (videos, RAW photos, documents) in just under a minute. This is a task that would have taken over 15 minutes on our old portable HDD. One user confirmed this leap in performance, stating it was “a lot faster than any of my previous drives, even other USB SSD drives.” Another user was thrilled after downloading “1500 plus pics to the devices in approx 4/5 mins.”
It is crucial, however, to address the reports of slow speeds. One frustrated user reported a transfer rate of only 14.64 MB/s. This is almost certainly a result of a port bottleneck. As another savvy user correctly pointed out, “Speed is going to be limited to your usb connection… If you’re buying this, make sure you’ve got a usb port that can handle the speeds.” Connecting this drive to an old USB 2.0 port will cap its speed at around 30-40 MB/s, while a USB 3.0 (Gen 1) port will limit it to around 400-450 MB/s. To get the advertised performance, a USB 3.2 Gen 2 (10Gbps) or faster port is required. We also tested it for video editing, using it as a working drive for a 4K project in DaVinci Resolve. The drive handled scrubbing through timelines and playback with no dropped frames, proving it’s more than capable for demanding creative workflows. The impressive speed is a key selling point for professionals.
Cross-Platform Compatibility and Versatility
In a world of diverse devices and operating systems, compatibility is king. The Lexar ES3 1TB Portable SSD excels in this regard. It comes pre-formatted as exFAT, allowing it to be read from and written to by both Windows and macOS systems right out of the box, no reformatting required. We tested this seamless transition, moving files from a Windows 11 PC to a MacBook Air without a single issue. The included USB-C cable with its integrated USB-A adapter is the unsung hero here, eliminating the need for extra accessories. As one user highlighted, “The short usb C-A cable is provided and that cable offers fast data transfer. And whats the best thing about this cable is that it has hidden usb C port inside the usb A cable end.”
Our testing went beyond traditional computers. We confirmed it works flawlessly with an iPhone 15 Pro Max for recording high-bitrate ProRes video directly to the drive, a game-changer for mobile filmmakers. One user specifically bought it for this purpose and was “surprised at how much space I have to record.” We also connected it to our PS5 to store and play PS4 games. While it worked well for this, it’s worth noting an updated review from one user who experienced repeated disconnections, suspecting overheating during extended gaming sessions. While we didn’t encounter this in our tests, it’s a critical data point for console gamers planning to use it for prolonged, intensive use. Furthermore, multiple users reported excellent performance on Linux, with one even installing and running a full Linux distribution from the drive, transforming their machine into a dual-boot system without partitioning the main drive. This level of versatility makes the Lexar ES3 1TB Portable SSD a true digital Swiss Army knife.
What Other Users Are Saying
Across the board, the feedback for the Lexar ES3 1TB Portable SSD is largely positive, with most users celebrating its core strengths. A common thread is praise for its “fab small and compact slim line design” and how it’s “light and easy to carry around.” Many, like the user backing up photos, found the transfer speeds “very acceptable” and appreciated the plug-and-play simplicity. Another, who uses it for video footage in their Model Y, noted its competitive price and lack of overheating issues in their specific use case. The convenience of connecting directly to a phone to offload photos was a highlight for one reviewer who was tired of complex, multi-device transfer processes.
However, the feedback isn’t universally glowing. The most significant negative point comes from a user who experienced “repeated errors due to the drive disconnecting unexpectedly” when used as expanded storage for a PS5, attributing the issue to potential overheating under sustained load. This is a critical consideration for heavy console gamers. Another point of contention, though minor for most, is the build material. One reviewer correctly pointed out, “It is all plastic though, even though it’s made to look like aluminium, it’s not.” Finally, the user who experienced “super slow” speeds serves as a crucial reminder for all potential buyers to check their host device’s port capabilities to avoid a performance bottleneck.
