It’s a scenario familiar to many PC builders and hardware enthusiasts. You’ve just upgraded your laptop or desktop with a blazing-fast, new-generation NVMe SSD. The performance leap is exhilarating, but it leaves you with a question: what becomes of the perfectly good, and still incredibly fast, drive you just replaced? Tossing it in a drawer feels like a monumental waste of potential. These tiny sticks of silicon hold hundreds, if not thousands, of gigabytes of data and can read and write files at speeds that were unimaginable just a decade ago. The problem is harnessing that power in a portable, convenient form factor. Standard external drives are often slow, bulky, and lack the sheer throughput to keep up with an NVMe SSD. This is where a specialized solution becomes not just a convenience, but a necessity, transforming that dormant component into a bespoke, high-performance external drive that you built yourself.
- USB Type-C 3 2 Gen 2 for transfer speeds up to 10 Gbps
- Supports M 2 PCIe NVM Express SSDs with 2230/2242/2260/2280 form factor M 2 NVMe SSD not included
What to Consider Before Buying an M.2 NVMe SSD Enclosure
An M.2 NVMe SSD enclosure is more than just a case; it’s a key solution for unlocking the full potential of your internal solid-state drives in a portable format. It bridges the gap between internal component and external peripheral, allowing you to create a custom, pocket-sized storage device with speeds that can rival internal drives. This is crucial for content creators moving large video files, IT professionals needing a fast bootable recovery drive, or gamers wanting to take their game library on the go without sacrificing loading times. The main benefits are flexibility—you choose the drive, the capacity, and the speed—and performance that far exceeds traditional USB flash drives or external hard disk drives.
The ideal customer for this type of product is someone who is comfortable with basic hardware installation and values performance and customization. This includes PC enthusiasts with spare parts, videographers who need to offload 4K footage quickly on location, and power users who demand the fastest possible data transfers between machines. Conversely, it might not be suitable for those who prioritize simplicity above all else and prefer a plug-and-play solution straight out of the box. For those users, a pre-built external SSD like the SanDisk Extreme or Kingston XS2000 might be a better, albeit less customizable, alternative. If you have no spare NVMe drives, the cost of buying both an enclosure and a new drive can sometimes exceed that of an integrated external SSD.
Before investing, consider these crucial points in detail:
- Interface & Speed: The most critical specification is the USB interface. The Asus ROG STRIX Arion M.2 NVMe SSD External Enclosure USB 3.2 Gen 2 uses the USB 3.2 Gen 2 standard, which provides a theoretical maximum speed of 10 Gbps (approximately 1,250 MB/s). Be sure your computer has a corresponding port to take full advantage of this. A faster 20 Gbps (Gen 2×2) enclosure won’t help if your device only supports 10 Gbps.
- Cooling & Thermal Management: NVMe SSDs can get incredibly hot under sustained load, leading to thermal throttling where the drive slows down to protect itself. A good enclosure must have effective cooling. Look for enclosures made from aluminum, which acts as a giant heatsink, and those that include thermal pads to bridge the gap between the SSD and the case for efficient heat transfer.
- Materials & Durability: The enclosure’s job is to protect your valuable drive. Aluminum alloy offers a fantastic combination of durability and heat dissipation. It’s far superior to plastic enclosures, which can trap heat and offer less physical protection. A solid metal build, as many users note, gives you confidence that the device can handle the rigors of travel.
- Ease of Use & Installation: How easy is it to install or swap a drive? Some enclosures require tiny screws and tools, while others, like the Arion, offer a “tool-less” design. This is a significant quality-of-life feature if you plan on swapping drives occasionally. Also, consider the included accessories, such as the type of USB cables provided (USB-C to C and USB-C to A are ideal for broad compatibility).
Choosing the right enclosure transforms a spare part into a high-performance tool, but getting it wrong can lead to bottlenecked speeds and overheating. The Asus ROG STRIX Arion aims to get everything right, but let’s dive into the details.
While the Asus ROG STRIX Arion M.2 NVMe SSD External Enclosure USB 3.2 Gen 2 is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: A Premium Feel from Box to Hand
From the moment you see the packaging, it’s clear the Asus ROG STRIX Arion M.2 NVMe SSD External Enclosure USB 3.2 Gen 2 is positioned as a premium product. The Republic of Gamers (ROG) branding promises performance and a certain aesthetic, and the Arion delivers. Unboxing it, we were immediately struck by its heft. At 98 grams without a drive, the solid aluminum alloy chassis feels less like a hollow case and more like a solid piece of machined metal. It feels substantial and cool to the touch, inspiring confidence in its durability. One user perfectly described it as an “absolute tank.”
Inside the box, Asus includes the enclosure itself, a stylish rubber bumper/holder with a cutout for a carabiner, a SIM-eject style pin for opening the case, and two high-quality braided cables: a USB-C to USB-C and a USB-C to USB-A. The inclusion of both cables is a thoughtful touch that ensures compatibility with a wide range of devices, from modern ultrabooks to older desktops. The star of the show, however, is the tool-less installation mechanism, which promises a quick and painless setup. The iconic ROG logo on the top is not just for show; it houses the ASUS Aura Sync RGB lighting, which immediately sets it apart from the sea of minimalist, purely functional enclosures on the market.

A Deep Dive Into the Asus ROG STRIX Arion’s Performance and Features
An enclosure can look good, but its true value is measured in performance, thermal efficiency, and ease of use. We put the Asus ROG STRIX Arion M.2 NVMe SSD External Enclosure USB 3.2 Gen 2 through its paces to see if the substance matches the style. Pairing it with a Samsung 980 1TB NVMe SSD, we tested everything from the installation process to its thermal throttling limits under extreme load.
The Definition of Tool-Less: A Seamless Installation Experience
Asus’s claim of a tool-less design isn’t just marketing fluff; it’s one of the Arion’s most significant strengths. The process is brilliantly simple. You use the included pin (similar to what you’d use for a smartphone’s SIM tray) to pop open the enclosure’s main latch. The top cover slides off smoothly, revealing the M.2 slot inside. What really impressed us was the SSD retention mechanism. Instead of a tiny, easy-to-lose screw that most other enclosures and motherboards use, the Arion employs a captive, rotating thumbscrew. You simply insert your M.2 NVMe drive (it supports all common form factors from 2230 to 2280), slide the thumbscrew into the drive’s semi-circular notch, and tighten it by hand. It’s a secure, clever, and genuinely tool-free system.
We did confirm a small detail that some users pointed out: it’s crucial to ensure the thumbscrew is seated correctly in its groove. If it isn’t, it can sit too high and prevent the top cover from closing properly. However, with a moment of attention, this is easily avoided. From opening the box to having a fully assembled external SSD took us less than a minute. This is a game-changer for anyone who might want to swap drives in the future. The simplicity is profound, as one user noted, “It is extremely easy to use! Took 10 seconds to put the drive in and secure it.” The absence of fiddly screws elevates the entire user experience, making it feel less like a delicate computer component and more like a robust piece of gear. This easy assembly process is a feature that truly justifies its premium positioning.
A Heatsink with Style: Build Quality, Thermals, and Aesthetics
The entire chassis of the Asus ROG STRIX Arion is, for all intents and purposes, a massive heatsink. The thick aluminum alloy construction isn’t just for show or durability; it’s fundamental to its thermal design. Inside, a pre-applied thermal pad makes direct contact with the top of your NVMe SSD. When the enclosure is closed, this pad transfers heat from the drive’s controller—the hottest part of the SSD—directly into the metal body, which then dissipates it into the surrounding air. This design is highly effective, perhaps a little too effective for some.
During our stress tests, which involved transferring over 900GB of mixed files, the enclosure became noticeably hot to the touch. One user described it as “burning HOT,” and while we wouldn’t go that far, it certainly gets well beyond “warm.” This is not a design flaw; it’s a sign that the enclosure is doing its job correctly. The heat is being pulled away from the sensitive drive and expelled. In our monitoring, the drive’s internal temperature remained well within safe operating limits, with no signs of thermal throttling, even after 30 minutes of continuous writes. The performance remained stable and consistent, which is the ultimate goal of any cooling solution. The takeaway is that the heat you feel on the outside is heat that isn’t cooking your SSD on the inside. Aesthetically, the Aura Sync RGB lighting is a signature ROG touch. It cycles through a rainbow spectrum by default but can be customized and synced with other Aura-compatible gear if you have the software installed. For many, it’s a cool visual flourish that makes the device stand out. For others, it might be overkill, but it undeniably contributes to its unique identity.
Blazing Fast, As Promised: Real-World Transfer Speeds
The Asus ROG STRIX Arion M.2 NVMe SSD External Enclosure USB 3.2 Gen 2 is built around the 10 Gbps USB 3.2 Gen 2 specification. In the real world, this translates to read and write speeds hovering just under the 1000 MB/s mark, after accounting for protocol overhead. Our tests confirmed this, with sequential read and write speeds consistently landing between 940 MB/s and 980 MB/s when connected to a compatible USB-C port on our MacBook Pro M1 and our Windows 11 desktop. This is incredibly fast for an external drive. Transferring a 50GB folder of video files took less than a minute.
These findings align perfectly with reports from other users. One owner using a MacBook Pro M1 reported “Read and Write speed of 950MB/sec… formatted as APFS,” which mirrors our experience. Another user working with a Crucial P3 Plus drive noted stable speeds that allowed them to move 900GB in under an hour. It’s important to set expectations correctly. You will not get the full 3,500 MB/s (or more) that your NVMe drive is capable of internally; the USB 10 Gbps interface is the bottleneck here. This is not a limitation of the Arion itself, but of the current universal standard for this price point. A user who mentioned a 20 Gbps (USB 3.2 Gen 2×2) port on their motherboard and was disappointed not to see faster speeds highlights this crucial point: the enclosure operates at the speed of its own interface, not the faster port it’s plugged into. For the vast majority of users with standard 10 Gbps ports, the Arion will max out the available bandwidth beautifully.
What Other Users Are Saying
Across the board, the sentiment for the Asus ROG STRIX Arion M.2 NVMe SSD External Enclosure USB 3.2 Gen 2 is overwhelmingly positive, centered on its build quality and performance. One user summed it up perfectly, calling it an “absolute tank — solid, dependable, and built to last.” This sentiment is echoed by many who praise the hefty, all-metal construction and its effectiveness as a heatsink. The tool-less installation is another universally loved feature, with many describing it as effortless and a significant improvement over competing products that require tiny screws.
However, the feedback isn’t without its criticisms. The most common complaint is the heat generated under load, with one user returning the device because it became “burning HOT.” While we determined this is a sign of proper thermal dissipation, it’s a valid concern for anyone who might need to handle the drive immediately after a large file transfer. Another recurring point of frustration revolves around missing accessories. Several users reported receiving units with missing screws (for the internal thumbscrew mechanism) or the hanging protective holder, suggesting some quality control inconsistencies in packaging. Finally, the price is a point of contention; as one user states, “I think this might be overkill for most, but if this is what you want, you will not regret it,” acknowledging that its premium features come at a premium cost.
Head-to-Head: Asus ROG STRIX Arion vs. The Alternatives
The Asus ROG STRIX Arion M.2 NVMe SSD External Enclosure USB 3.2 Gen 2 offers a fantastic blend of DIY flexibility, performance, and rugged, gamer-centric design. However, it exists in a competitive market with excellent pre-built solutions and niche alternatives. Here’s how it compares to three other popular options.

The Kingston XS2000 is a pre-built portable SSD that challenges the Arion on pure speed. It utilizes the faster USB 3.2 Gen 2×2 interface, capable of speeds up to 2,000 MB/s—double that of the Arion. If you have a device with a compatible Gen 2×2 port and your top priority is absolute maximum transfer speed in a compact, all-in-one package, the Kingston XS2000 is the clear winner. However, the vast majority of computers do not have a Gen 2×2 port, meaning the XS2000 will default back to 10 Gbps speeds, putting it on par with the Arion. The Arion’s main advantages are its DIY nature, allowing you to repurpose an old drive or choose a specific one, and its superior thermal management due to its larger, all-metal body.
