There’s a specific, heart-sinking moment every content creator knows. We were on location, filming what was supposed to be the cinematic B-roll for a major project. The light was perfect, the talent was in the zone, and the iPhone 15 Pro was capturing stunning 4K ProRes footage. Then, the dreaded notification popped up: “iPhone Storage Almost Full.” The flow was broken, the momentum lost. We had to stop, offload files to a sluggish older drive, and waste precious minutes of golden-hour light. It was a stark reminder that in today’s world of massive file sizes, the speed and accessibility of your storage are just as critical as the quality of your camera. This bottleneck isn’t just an inconvenience; it can be the difference between capturing a masterpiece and settling for a missed opportunity. It’s this exact problem that drives the search for a new breed of external storage: something fast, capacious, and seamlessly integrated into a mobile workflow.

What to Consider Before Buying an External Solid State Drive
An External Solid State Drive is more than just an item; it’s a key solution for breaking through digital limitations. Unlike traditional hard disk drives (HDDs) with their spinning platters, SSDs use flash memory, resulting in blistering speeds, superior durability, and a much smaller physical footprint. For video editors, this means no more choppy playback of 4K timelines. For photographers, it means importing and culling thousands of RAW photos in minutes, not hours. For gamers, it’s the end of agonizingly long load screens. And for the modern mobile creator, it’s the freedom to record high-quality video directly from a device like the iPhone 15, completely bypassing the phone’s internal storage limits.
The ideal customer for this type of product is someone whose work or hobby involves frequent interaction with large files. This includes videographers, photographers, graphic designers, software developers, and serious gamers. If you’ve ever found yourself waiting for a file to transfer and thought, “There has to be a better way,” an external SSD is likely for you. On the other hand, if your storage needs are limited to backing up text documents and a few family photos, the performance of a high-speed SSD might be overkill. In that case, a more affordable portable HDD or a simple cloud storage subscription could be a more practical and cost-effective choice.
Before investing, consider these crucial points in detail:
- Dimensions & Portability: The primary benefit of an external drive is its portability. You should look for a device that is compact and lightweight enough to slip into a pocket or camera bag without a second thought. The Lexar 2TB ES4 Portable SSD, for instance, weighs a mere 95 grams. Consider the build materials and any included cases or sleeves that add to its travel-readiness.
- Capacity & Performance: Don’t just look at the gigabytes (GB) or terabytes (TB); understand the speed. The interface is key: USB 3.2 Gen 2 (like on the ES4) offers a theoretical max of 10 Gbps (~1250 MB/s), while the faster USB 3.2 Gen 2×2 doubles that. Always treat advertised speeds as “up to” maximums, as real-world performance will vary based on your computer, the cable, and the type of files you’re transferring. 2TB is a fantastic sweet spot for most creative professionals, offering ample room for multiple large projects.
- Materials & Durability: SSDs are inherently more durable than HDDs because they have no moving parts. However, the quality of the external casing matters. Many drives, like this one, are designed to be shock-resistant. Look for metal or high-impact plastic enclosures, and consider models with official IP (Ingress Protection) ratings for dust and water resistance if you often work in challenging environments.
- Ease of Use & Compatibility: A great external SSD should be plug-and-play. Check what cables are included; a drive that comes with both USB-C to USB-C and USB-C to USB-A cables, as the Lexar 2TB ES4 Portable SSD does, offers maximum versatility out of the box. Also, consider any included software, such as encryption tools for data security, and check for compatibility with your primary operating systems (Windows, macOS, etc.).
Making the right choice in this category can dramatically improve your workflow and secure your valuable data.

Unboxing the Lexar ES4: First Impressions and Magnetic Magic
Upon opening the box, the Lexar 2TB ES4 Portable SSD immediately makes a statement about its intended purpose. The package is lean and focused, containing the drive itself, a grippy silicone case, a thin magnetic ring with adhesive backing, a high-quality USB-C to USB-C cable, and a legacy-friendly USB-C to USB-A cable. The drive itself is incredibly small and light, easily dwarfed by a modern smartphone. Its smooth, dark casing feels premium and understated. Sliding it into the silicone case adds a welcome layer of protection and grip. But the star of the show is undeniably the “Snap and Go” magnetic system. This isn’t just a gimmick; it’s a thoughtfully designed solution aimed directly at iPhone 15/16 users. The idea of securely snapping a 2TB drive to the back of your phone for direct ProRes recording is, frankly, a game-changer. The initial impression is that Lexar didn’t just build another fast SSD; they built a complete workflow tool, which is a feature that truly sets it apart in a crowded market.

Putting the Lexar 2TB ES4 to the Test: A Deep Dive into Performance
A product’s spec sheet only tells half the story. The promise of “up to 1050MB/s” and a revolutionary magnetic system demands rigorous, real-world testing. We spent weeks integrating the Lexar 2TB ES4 Portable SSD into our daily workflow, using it for everything from large-scale video edits on a MacBook Pro to direct-to-drive recording on an iPhone 15 Pro Max and even as a game library for a PS5. Our goal was to push it beyond simple benchmarks and see how it holds up under the pressures of a demanding creative environment.
Real-World Speed and Transfer Benchmarks
Lexar advertises impressive peak speeds of 1050MB/s read and 1000MB/s write, typical for a top-tier USB 3.2 Gen 2 drive. To validate this, we connected it to our MacBook Pro M1’s Thunderbolt/USB 4 port and ran a series of tests using Blackmagic Disk Speed Test and F3, mirroring the methodology of other tech-savvy users. Straight out of the box in its default exFAT format, our 5GB stress tests yielded results that, while fast, didn’t quite hit the advertised ceiling. We consistently saw read speeds hovering between 750MB/s and 900MB/s, with write speeds ranging from 600MB/s to 820MB/s. After reformatting the drive to APFS for optimized use within the Apple ecosystem, we saw a slight, consistent improvement, but the 1000MB/s barrier remained elusive.
Is this disappointing? Not necessarily. It’s crucial to understand that “up to” speeds are theoretical maximums achieved under perfect laboratory conditions. In the real world, factors like operating system overhead, file system structure, and the nature of the data itself (transferring one massive 100GB video file will always be faster than transferring 100,000 tiny text files) will always reduce peak performance. For all practical purposes, 800MB/s is incredibly fast. It allowed us to transfer a 50GB 4K video project in just over a minute and scrub through a multi-layered editing timeline with zero lag. It’s a massive leap over older portable drives. However, we must also address the elephant in the room. Our experience was positive, but we are aware of a number of user reports that paint a drastically different picture. Some have experienced catastrophic performance issues, with speeds plummeting to a sluggish 30MB/s, indicative of the drive falling back to a USB 2.0-like state. One user even reported a complete drive failure resulting in the loss of 500GB of data. While we cannot replicate this failure on our test unit, the existence of these reports suggests a potential for quality control inconsistency that prospective buyers should be aware of. It’s a reminder to always have a multi-tiered backup strategy for mission-critical data, regardless of the drive you use. For those who prioritize raw, consistent speed, it’s worth seeing the full feature set and user reviews to weigh the risks against the benefits.
The Magnetic Kit: A Game-Changer for iPhone Videographers?
This is where the Lexar 2TB ES4 Portable SSD truly distinguishes itself from the pack. The “Snap and Go” magnetic kit is, without exaggeration, a brilliant piece of design. We tested it with an iPhone 15 Pro Max. The process is simple: you either apply the thin adhesive magnetic ring to the back of your phone or case, or, even better, use a MagSafe-compatible case. The SSD, snug in its silicone sleeve, then snaps onto the back with a satisfying and secure clack. The magnetic hold is strong enough for stationary tripod shots, vlogging, or handheld shooting with steady movements. While we might be hesitant to trust it during a frantic run-and-gun scenario, it’s more than adequate for 95% of mobile filmmaking situations.
The workflow improvement is immediate and profound. Plugging the included USB-C cable from the drive into the phone, the Camera app instantly recognizes the external storage, showing “USB-C” on the screen. We could then record 4K 60fps ProRes video directly to the ES4, completely bypassing the phone’s internal storage. We recorded over an hour of continuous footage without a single dropped frame or hiccup, a feat that would have been impossible using the iPhone’s internal memory. This completely changes the game, turning the iPhone into a legitimate cinema camera for long-form content like interviews, events, and podcasts. Some users have reported initial connection issues, but we found that using the high-quality supplied cable and ensuring the phone’s software was up-to-date resulted in a flawless connection every time. Furthermore, the magnetic utility extends beyond the phone. As one clever user noted, it’s fantastic for sticking the drive to the side of a metal PC case, keeping your desk setup clean and tidy. It’s this kind of thoughtful, versatile design that makes the Lexar 2TB ES4 Portable SSD a compelling option.
Broad Compatibility and Data Security
Beyond its iPhone-centric magnetic feature, the Lexar 2TB ES4 Portable SSD is a remarkably versatile and capable all-rounder. The inclusion of both USB-C to USB-C and USB-C to USB-A cables in the box is a huge plus, ensuring you can connect to virtually any modern or legacy device without needing to buy extra dongles. We tested it seamlessly with a Windows 11 laptop, an Android tablet (a Samsung Note, as one user confirmed), and most impressively, a PlayStation 5.
On the PS5, the drive was immediately recognized and formatted as extended storage. While you can’t play PS5 games directly from it, we were able to transfer our entire library of PS4 games to the ES4, freeing up precious internal console storage. Games loaded quickly, with performance indistinguishable from the internal drive. It’s an excellent, cost-effective way to expand your console’s capacity. For professionals handling sensitive information, the included Lexar DataShield software is a significant value-add. It allows you to create a password-protected, encrypted vault on the drive using 256-bit AES encryption—the same standard used by governments and security agencies. This provides peace of mind that if the drive is ever lost or stolen, your data remains secure from prying eyes. This combination of wide-ranging compatibility and robust security makes the Lexar 2TB ES4 Portable SSD a reliable digital Swiss Army knife for nearly any scenario.
What Other Users Are Saying
Across the board, user feedback for the Lexar 2TB ES4 Portable SSD is a mix of high praise for its innovative concept and sharp criticism regarding its consistency. On the positive side, many users are thrilled with the magnetic system. One user celebrated its convenience, stating, “I love that this SSD has a magnet on the back… it also sticks to the side of my computer case,” highlighting its versatility beyond just phones.
Another, using it with a MacBook Pro, was “satisfied with the performance,” acknowledging that while speeds didn’t hit the advertised maximum, they were still very fast for real-world use, clocking in between 600-900MB/s. However, the negative feedback is significant and cannot be ignored. The most alarming report comes from a user who experienced a catastrophic failure, claiming the drive became corrupted, leading to the loss of “over 500GB of important content” after delivering speeds of only 30MB/s. Another user expressed frustration that “It’s doesn’t work with my iPhone 15 pro max,” though they later got it working with a laptop. This feedback paints a picture of a product with a brilliant core idea that may be hampered by inconsistent performance and potential reliability issues in some units.
