    Sabrent EC-SNVE

    A tool-free enclosure: a side button pops a lid that folds back 180 degrees. Tom’s Hardware names it the best M.2 SSD enclosure for most people and measured 811MBps reads and 538MBps writes. If your drives are all NVMe, Sabrent’s newer EC-PNVO is a good fit too: it runs at up to 10Gbps and takes 2230 to 2280 drives, but Sabrent says it accepts NVMe only, not M.2 SATA.

M.2 SSD enclosures · tier 2 of 4

20Gbps

USB 3.2 Gen 2x2 enclosures for an M.2 NVMe drive, at twice the speed of a 10Gbps one. They need a Gen 2x2 port on the computer: many computers, including some with USB4 or Thunderbolt ports, stop at 10Gbps, and the enclosure then runs at that speed. The bridge chip must be named, by the maker or by the named review.

80Gbps Thunderbolt 5 enclosures for an M.2 NVMe drive, twice the speed of a USB4 one. Full speed needs a Thunderbolt 5 host; on an older Thunderbolt or USB4 port the enclosure runs at that port’s speed. The bridge chip must be named, by the maker or by the named review.

10Gbps sticks

Flash drives that run at USB 10Gbps, the fast end of the stick: some hold a real SSD inside. Tom’s Hardware says the fastest approach some external SSDs, and that an external SSD is usually the better buy if speed is the point and a cable is no trouble.

Everyday and big capacity

Sticks for moving files, from a metal everyday drive to the one picked for a lot of space. The bar is a USB 3.2 link and a warranty of three years or more, so the drive is at least well-rounded.

    • You use a USB-A port or a console: the maker lists PlayStation and Xbox support.

    A premium Thunderbolt 5 dock for Windows and Mac with 20 ports, 10GbE and DisplayPort 2.1. Tom’s Hardware picked it as the best premium Thunderbolt 5 dock for Windows laptops.

    Suits you if

    • You run several monitors, a wired network and fast storage from one laptop port.
    • You want 140W to the laptop: the maker says the power supply holds 140W as you add devices.

    Skip it if

    • Your computer has Thunderbolt 3 or only a 5Gbps or 10Gbps USB-C port: the maker says the TS5 Plus does not work with those hosts.

How we pick

An enclosure becomes a pick when its bridge chip is named, by the maker or by the review that tested it, it has a metal body to carry heat off the drive, and a published test of it is saved in our library. A card has to be a true microSD Express card, the only kind the Switch 2 accepts for game storage, with a lifetime warranty (some makers call it limited). Every spec on a card comes from the maker’s own page or data sheet; a part a maker does not name comes from the named review, and the card says so.

A flash drive has to be a tested stick with a named USB link and a warranty of three years or more; the fast tier asks for USB 10Gbps and five years. A Thunderbolt 5 or Thunderbolt 4 dock has to state its Ethernet speed and have an SD UHS-II slot, a DisplayLink dock has to run two 4K 60Hz monitors from one USB-C cable with Gigabit Ethernet and at least 85W of charging, a USB-C hub has to pass through at least 100W of charging, and a USB-A hub has to run every port at 5Gbps. A card reader has to name the cards it reads and its USB link. For the docks, hubs, flash drives and readers, the maker’s own page or data sheet is the source of each spec; where it is silent on one (a stick’s warranty, say), the card names the review it came from. A pick whose maker page we cannot save is not a pick, and the Also considered list says so.

Popularity and commission play no part: a product is here because of its specs and a test, not because it sells well. We check the picks again when new reviews come out.

Reading the cards

An enclosure’s speed depends on three things: its link, the port on your computer and the drive inside. A USB4 enclosure on a 10Gbps port runs at 10Gbps, and a USB 10Gbps enclosure stays at 10Gbps even on a USB4 or Thunderbolt port. A 20Gbps enclosure needs a USB 3.2 Gen 2x2 port for its full speed, and a Thunderbolt 5 enclosure needs a Thunderbolt 5 host for its 80Gbps. Use the cable that came in the box.

The same rule runs through the rest of the page. A flash drive, a hub or a card reader runs at the slowest link between it and your computer: a 10Gbps stick in a 5Gbps port runs at 5Gbps, a hub shares one upstream link among everything plugged into it, and a USB4 CFexpress reader drops under 900MB/s in a USB 3.x port. A dock needs the host it was built for: a Thunderbolt 5 dock wants a Thunderbolt or USB4 port, and CalDigit says the TS5 Plus does not work with Thunderbolt 3 Windows PCs. A DisplayLink dock works from a plain USB-C port but needs its driver, and on a Mac, DisplayLink says protected video may play black while one of its screens is connected. Card reader speeds are the makers’ ratings, and the speeds quoted from reviews are what the reviewer measured with one test card.

Card speeds are the makers’ ratings for microSD Express mode. In an older microSD slot the same card falls back to UHS-I speed. This page does not show prices, because a page built once cannot keep a price current.

Questions before you buy

Will my SSD fit?

Check the type and the length. Most M.2 enclosures take NVMe only, and so do most of the picks here, so an M.2 SATA drive will not work in them; the Sabrent EC-SNVE is the exception, and Sabrent lists it for both NVMe and SATA. The Sabrent takes 2230, 2242, 2260 and 2280 drives, the Asus ProArt takes 2230 and 2280 drives, the UGREEN also takes 2242 and 2260, the SilverStone takes 2242, 2260 and 2280, and the TerraMaster takes 2280 only. Best SSDs.

Do I need 20Gbps, USB4 or Thunderbolt 5, or is 10Gbps enough?

Each step up needs a matching port. A 20Gbps enclosure needs a USB 3.2 Gen 2x2 port, and Tom’s Hardware says even a USB4 or Thunderbolt port may cap it at 10Gbps. A USB4 enclosure runs at 40Gbps, about four times a 10Gbps one, but only on a USB4 or Thunderbolt port, and Tom’s Hardware found one USB4 model that would not work on a non-USB4 port at all. A Thunderbolt 5 enclosure reaches 80Gbps only on a Thunderbolt 5 host. On any other port each one runs at that port’s speed.

Why is my drive, hub or reader slower than its rating?

It runs at the slowest link in the chain: its own link, your port and the cable. A 10Gbps flash drive in a 5Gbps port runs at that port’s speed, though Tom’s Hardware still found the fast ones far ahead of old low-end drives there. A USB4 CFexpress reader drops under 900MB/s in a USB 3.x port, Digital Camera World says, and a hub shares its one upstream link among everything plugged into it. Use the cable in the box or one rated for the speed you paid for. Cloning and backup in 2026.

Flash drive or portable SSD?

Tom’s Hardware says the fastest flash drives come close to some external SSDs, but if speed matters and a slightly bigger device with a cable is fine, an external SSD is usually the better buy. Stick SSDs such as the ADATA SC750 are also wider and can block the port beside them. Tom’s Hardware warns that no-name 2TB sticks at very low prices are often scams. Best SSDs.

Do I need a dock, or is a hub enough?

A hub adds ports; a dock adds ports plus more bandwidth, charging and extras such as faster Ethernet. Tom’s Hardware says a hub with a 10Gbps USB-C link can limit you if you often move large files between fast devices, and a dock with a Thunderbolt 4 or USB4 upstream port gives more bandwidth. The Thunderbolt 5 docks here need a Thunderbolt or USB4 host: CalDigit says the TS5 Plus does not work with Thunderbolt 3 Windows PCs or with 5Gbps and 10Gbps USB-C hosts. For a laptop without Thunderbolt, the DisplayLink docks here run two monitors from an ordinary USB-C port through a driver. They also work on a Mac with the DisplayLink driver, one way to run two monitors from a MacBook that drives only one external display on its own: Kensington says MacBooks with a base M1 or M2 chip get one external display from its Thunderbolt 4 dock. DisplayLink lists two limits on macOS. The driver needs the Screen Recording permission, and once one DisplayLink screen is connected, protected video in apps such as Netflix, Disney+ and Amazon Prime may stay black on every screen while the audio plays. DisplayLink support: protected video on Mac.

Why does the Switch 2 need microSD Express?

The Switch 2 takes only microSD Express cards for game storage. An Express card adds a PCIe and NVMe link on top of the usual microSD interface, which is how it reaches read speeds around 800MB/s. An ordinary microSD card has no such link. SD and microSD cards: classes, bus modes and SD Express.
