One thing we appreciated about the design of the UGREEN enclosure is the easy, tool-free installation. The outer shell of the case is hollow, and you can slide it off with a little effort. Once you’ve pulled out the inner case, you install your M.2 drive in the enclosure. It’s large enough to fit any standard-sized NVMe drive: 2230, 2242, 2260, and 2280 will all fit. Most M.2 drives aren't exactly pretty; they look like bare circuit boards with silicon chips grafted onto them. Some may be topped by a heat spreader or heatsink (usually an array of metal fins) that is equal parts practical and decorative. The most important thing to know about M.2, though, is what it is and what it isn't. An unapologetically bright RGB-lit PCIe 3.0 NVMe M.2 SSD, the S40G will bling up your PC if you're an enterprising builder. Its 4K read and write speeds should keep most gamers happy, too. Of course, to show off the lighting, you will need to have an open-frame rig, or one with a transparent-sided case. If you've already RGB'd your keyboard, mouse, video card, motherboard, case, and headphones, and are at a loss for what's left, the Spectrix S40G makes enough sense both in performance and looks to belong in any lighting-obsessed custom PC builder's arsenal. The ORICO M.2 NVMe SSD Enclosure is made entirely from aluminum and boasts a 10-minute automatic sleep mode.

Although M.2 is commonly referred to as an interface, that's not the whole story. M.2 is also a shape or physical form factor, and governs the keying that lets a drive fit onto a motherboard. The StarTech.com USB-C M.2 NVMe PCIe SSD Enclosure is drop-proof and waterproof for extreme durability.The thermal pad inside the housing provides good temperature protection. The 10Gbps data transfer is just what you’d expect for a USB Type-C enclosure. It supports up to a 2TB drive, which was somewhat disappointing. But there’s a 20-inch USB Type-C to Type-C cable, so you’ll have plenty of reach to plug into your devices. Final Verdict The T700 is for gamers, creatives, and professionals seeking the ultimate in solid-state drive performance that today only a Gen 5 SSD offers. Just know that being able to run a PCI Express 5.0 SSD at peak speeds can require a considerable additional hardware investment. You must be willing to buy a recent desktop with the hardware to support SSDs built on the PCIe 5.0 standard, upgrade an existing recent rig, or build one from scratch. By making such an investment and having the T700 serve as its brains, though, you're future-proofing your entire setup. Third on our list was the ORICO M.2 NVMe SSD Enclosure. This is a more affordable enclosure that can get you set up on a budget. It’s compatible with both SATA and NVMe SSDs, so you don’t have to worry about what type you’re using. And while it only supports up to a 2TB drive, you get the benefit of a 10-minute auto-shutoff timer to save power. In recent years, M.2 drive technology has been changing how we think about storage. Traditional storage has either been internal or external. Yes, you can swap out a traditional 2.5” or 3.5” internal drive if you want to. But there are multiple steps involved. An M.2 drive is a drop-in solution that can be implemented not just in full-sized PCs but in portable systems.

The data bus, or pathway, over which your data travels to and from an M.2 drive is a whole other matter, which is where PCI Express and NVMe come in. We'll get to the significance of NVMe in a moment; first, let's discuss the key physical traits of an M.2 drive that you need to understand. (The video below is a good primer.) If you're a custom PC builder with RGB-lighting fever, and have RGB-ified just about every inch and corner of your system, perk up: ADATA has brought pretty lights to the internal SSD final frontier. The XPG Spectrix S40G is the most flamboyant NVMe drive we've seen to date. With the S40G's fine 4K write speeds, top-notch sequential-read speeds, and respectable durability rating, ADATA makes having a top-of-the line, over-the-top SSD affordable and fun, in one fell swoop. Who It's ForAlso, make sure that if your system supports and you're shopping for an NVMe drive, any PCI Express drive you're considering is specifically an NVMe model. Merely using the PCI Express bus is not necessarily a guarantee of that; PCIe M.2 SSDs existed before NVMe, and though all current models support NVMe, some oldies are still on the market. Today's mainstream solid-state drives are PCI Express 3.0 and 4.0 x4 NVMe M.2 devices, and they leave the fastest SATA-based drives in the dust. The USB port supports the USB 3.2 data transfer standard. This allows you to read and write files at a rate of up to 10Gbps. The enclosure itself will support up to a 8TB drive. That’s a larger capacities than most enclosures will allow. A pair of 12-inch cables are included for connecting to your computer or other device. Both are male-to-male, and one is USB Type-C to Type-C, while the other is Type-C to Type-A.

Depending on what you need, any one of these M.2 SSD enclosures could be the best choice. But what sets one apart from another? Here’s what we’ve learned about each of these enclosures. Samsung 970 EVO​i want to put in a caddy to either use as an external drive or maybe format and put into pc for a game or 2 it is only 250GB(has The old OS on and keeps booting instead of new drive Now let's reiterate an important point: You may know an M.2 solid-state drive's length and capacity, but that doesn't tell you about the bus or interface it makes use of. That detail is vital to know—just as important as making sure the drive physically fits in the space you have.The UGREEN M.2 NVMe SSD Enclosure is an aluminum and silicone enclosure that allows for tool-free installation. We've already mentioned one you know—SSD. It stands for "solid-state drive," a storage drive made up of flash memory in modules called NANDs and governed by a controller chip. (The name NAND comes from a type of logic gate in Boolean algebra; we'll try to explain terms as we go along, but if you need a refresher in SSD lingo see our rundown of 20 terms you need to know.) Unfortunately, SSD shopping has been complicated in recent years by the emergence of three new technologies: M.2, PCI Express (abbreviated PCIe), and NVMe. All three are centered around making SSDs smaller or faster. They also make buying a solid-state drive more challenging than ever.

Of course, these are just the basics. To truly understand these enclosures, we’re going to have to take a much closer look. Once we’ve given them a thorough evaluation, we’ll know enough to deliver a verdict. Let’s get started! Best Overall: UGREEN M.2 NVMe SSD Enclosure Until the last few years, the typical SSD was a little slab, designed to fit into the same space or drive bay inside a PC as a spinning hard drive. You can still find SSDs in this form factor, known as 2.5-inch drives, but times have changed. Many of today's premium laptops can make use of PCI Express M.2 drives. (Important: Some, like the latest Apple MacBooks, have PCI Express drives soldered, in not-upgradable fashion, to the laptop's mainboard, so "PCI Express SSD" doesn't necessarily imply "removable M.2 SSD module.") As mentioned, almost all new desktop motherboards have M.2 slots, most of which support PCI Express drives. In practice, all of today's PC builder- or upgrader-minded M.2 drives and slots are 22mm wide, so you can expect this number to start with 22. The most common lengths are 80mm (M.2 Type-2280) and 60mm (M.2 Type-2260). Drives as short as 30mm (M.2 Type-2230) or as long as 110mm (M.2 Type-22110) do exist, however. Why the differences in length? The longer the drive's PCB (printed circuit board), the more surface area it has to hold memory chips.You can use these PCIe 4.0-based SSDs in PCIe 3.0-only systems, but they'll just dial down to PCIe 3.0 speeds. So should you opt for one? If you'll be assembling or upgrading a late-model AMD or Intel PC with the right chipset, by all means. Hardcore gamers and content creators working on today's newer PCs will stand to gain the most. If you have a PCIe 4.0-capable slot for one, get one; otherwise, 3.0 will likely do you fine. Installing your M.2 SSD is straightforward, although you’ll need to use the included small screwdriver. Remove the screw from the lid and slide it away to reveal the inner housing. Inside is a thermal silica gel pad that helps transfer heat to the outside. The compartment will accommodate any sized M.2 SSD, from 2230 all the way up to 2280. And it supports both NVMe and SATA SSDs, so you don’t have to worry about compatibility.
