To install our drive in this enclosure, we first had to remove the aluminum panel, which is attached with a tiny, 5-point star screw rather than a normal Philips head type. The enclosure comes with a small star-shaped screwdriver, but we lost it and had to go digging through our iFixit kit to find an appropriate head. I've got a Shinestar NVMe enclosure, but it tops out around 1GB and I know these drives go faster when plugged directly into an M2 slot. The DIY-friendly design is further emphasized by the exclusive Q-latch mechanism, which promises an easy mounting process for the SSD into the enclosure. If you want an SSD enclosure with some RGB bling and a swanky sci-fi design, Asus’s ROG Strix Arion is for you. The M.2 NVMe enclosure has two RGB lights, an illuminated ROG logo on the top and a small plastic fin on the side. These show a pleasing pink and purplish light show which Asus markets as being part of its “Aura Sync” RGB ecosystem. However, there doesn’t seem to be any way to actually control the lights as the Asus Armoury Crate software we tested with did not recognize the drive.

One last caveat to drop in before we get to our product recommendations surrounds Intel's SSD line. Intel for a while sold a family of M.2-based storage products under the brand name Optane, in two very distinct types of drive. Intel's"Optane SSDs"were SSDs like any other, bootable drives that can serve as a stand-alone boot drive or as secondary storage. They were discontinued for consumers in 2021, but you may still see them around. (Intel sold its SSD business at the end of 2021 to SK Hynix, which spun it off into a new subsidiary, Solidigm.) Now, to reiterate an important point: A drive may come in the M.2 form factor, but that says nothing about the bus that it makes use of. Determining that is just as important as making sure it fits. But how will an enclosure behave in a real-world-like gaming scenario? Load times in the FF XIV standalone benchmark are actually quite impressive, especially when compared to an internal hard drive. Interestingly, a 20 Gbps enclosure seems to offer some improvements here as well.

The Samsung SSD 990 Pro, the company's flagship PCI Express 4.0 NVMe internal solid-state drive, has a hard act to follow in the Editors' Choice-winning SSD 980 Pro, but for the most part it makes a great product even better. This power-efficient drive gets high marks for raw speed, everyday application performance, a strong software suite, and hardware-based encryption. The heatsink-equipped version of this drive performed slightly better than the non-heatsink version (which we tested using our testbed's motherboard's heatsink) in most of our benchmarks. It doesn't quite merit the 980 Pro's Editors' Choice award, because other recent internal SSDs have outpaced it in our gaming benchmarks, but its overall capability makes this Samsung a versatile drive well-suited for creative tasks. Who It's For If cost is a concern, go with a PCIe 3.0 M.2 NVMe SSD like Crucial P2 and an enclosure like Orico M2PV-C3. If your device has a Thunderbolt 3 port, you can opt for a PCIe 4.0 M.2 NVMe SSD like Samsung 980 PRO and an enclosure like OWC Envoy Express.

Cheap PNY 8GB commodity drive. Thing was so damned slow I changed it to 512GB and only ran 1 pass. Thats not a mistake, the random write tests are slow low as to not even register. RND4KQ32T16 is something like .0003MB/s. Generally if the drive is readable I'll boot off a custom WinPE disk I built and run USMT to salvage the user profile data to a compressed MIG store. Then I'll replace the drive or laptop, re-image, and restore the salvaged profile. So the faster the drive is the faster I can complete these tasks. Which makes users happier. I've been using a M2 Sata enclosure, but I also have 2.5" external cables that let me plug a 2.5" directly into a USB port.

This is one of the most performant 10 Gbps enclosures and one of the most convenient, thanks to a tool-free design that allows you to slip the cover off by pressing a spring-loaded switch. It's a few dollars more than the Sabrent EC-SNVE at present and we prefer that enclosure's flip-up lid to the Plugble's slide-out one. In terms of performance, the Asus enclosure is on par with other 10 Gbps models, but the main selling point here is design – especially the Strix Owl RGB highlights.It is plug-and-play supported. However, you would need a screwdriver to install your drive inside it. You also get an LED indicator. Designed to accommodate M and B&M keys along with a broad spectrum of SSD sizes ranging from 2230 to 2280, it offers a home for SSDs with capacities of up to 8TB. A notable convenience is the inclusion of two cables: a USB Type-C cable and a USB Type-C to USB Type-A cable. This again can be set up without the need of any toolkit at all. The design of this enclosure is much more rugged and unique in its own way. Some people might not like but I personally liked it. It lends support to UASP and Trim protocols, armed with the advanced RTL9210B chip that works tirelessly to prevent short-circuits and over-current scenarios, promising a secure and stable environment for your SSD. At this price point, you can easily get an external SSD. But, ROG Strix Arion has got its own unique features. The device leverages the capabilities of USB Type-C 3.2 Gen 2 technology, providing data transfer speeds of up to 10 Gbps. But, again, it only supports M.2 NVMe SSDs, not M.2 SATA SSDs.

On a few M.2 enclosures, including the SSK SHE-C325, we found that our test Kingston Rage Fury SSD’s built-in graphene heat spreader, which adds 3.5mm of z height to the drive, didn’t leave much vertical clearance. However, the SHE-C325 could close anyway, without scraping the drive’s surface. Considering that many M.2 SSDs have built-in, non-removable heat spreaders, every enclosure should accommodate them. Of all three the Shinestar M.2 was the hottest enclosure. Even just sitting idle the enclosure was uncomfortably hot to the touch. It also suffered from random disconnects and at times would not mount. How often will you open it? Most of the M.2 SSD enclosures we tested were made to be opened once, have a drive installed inside and then screwed closed for the long haul. While you can reopen all of them and change drives at any time, you should consider an enclosure with a tool-less design if you think you’ll be changing the drive frequently.Which form factor? You have to get an SSD enclosure that matches the physical size of your drive. If you have a 2.5-inch hard drive or SSD, get a 2.5-inch SATA enclosure. For a 3.5-inch hard drive, you’ll need a 3.5-inch SATA enclosure. M.2 SSDs require M.2 enclosures, but be careful if your SSD is shorter than the standard 2280 (80mm size); most but not all enclosures have mounting screws for the shorter sizes. Also, if you plan to use an M.2 SATA SSD, as opposed to an NVMe one, make sure that the enclosure supports that standard instead (or in addition), because most M.2 enclosures are NVMe only. Next is the fastest USB thumb drive I own. These predate me having the USB External M2 adapters. So I used to use them for salvage. Most of the time now they run various bootable things. But the read/write speeds are still impressive for a true USB Thumb drive. Sandisk Extreme 64GB (CZ80) The SHE-C325 isn’t the most attractive enclosure on the market, but it does use mostly aluminum casing (the left part near the USB port is plastic) and at 4.5 x 1.5 x 0.4 inches, it’s pretty portable. SSK’s enclosure also comes with a thermal pad to help send heat to the aluminum casing, but you’ll only want to use it if your SSD doesn’t have a built-in heat spreader. TDBT M.2 NVMe SSD Enclosure with Heat Sink, 10Gbps USB-C to PCIe NVMe M.2 Hard Drive Enclosure with Thermal Cooling Pad, NVMe M.2 Drive to USB-C External Storage Enclosure, Fits M-Key B+M Key NVMe SSDby TDBT The earliest versions of M.2 PCI Express SSDs made use of the PCI Express Gen 2.0 x2 interface, which defines a throughput ceiling that's higher than SATA 3.0's, but not enormously so. That evolved into PCI Express Gen 3.0 x2 and x4, paired with a technology called Non-Volatile Memory Express (NVMe) to propel performance even further, especially with heavy, deeply queued workloads.
