This week ADATA launched what it called an “industry first” portable SSD capable of read/write speeds up to 3,800MB/s and 3,700MB/s thanks to a combination of a fast SSD, a fan for active cooling, and a USB4 port with support for 40 Gbps data transfer speeds.

But it turns out “first” is debatable, because there are already a few USB4 SSD enclosures available that are capable of delivering similar speeds when you bring your own SSD, and more are on the way.

ZikeDrive USB4 SSD enclosure

Most of the true USB4/Thunderbolt 4 SSDs and enclosures available so far are using the same controller, AS Media’s ASM2464PD, which is designed to support PCIe Gen 4 x4 NVMe SSDs and features two USB4/Thunderbolt 20 Gbps PHYs.

For example, the ZikeDrive Z666 is a USB4 enclosure with an aluminum case for heat dissipation and room inside for an M.2 2280 PCIe NVMe SSD.

Zike says it supports read speeds up to 3.8 GB/s and write speeds up to 3.1 GB/s, and the enclosure measures 112 x 67 x 18mm (4.4″ x 2.6″ x 0.7″ and weighs 245 grams (8.6 ounces). It has a list price of $199, but the ZikeDrive Z666 is on sale for $129.

Another option is the HyperDrive Next USB4 enclosure. This model has a list price of $120, but it’s currently out of stock.

According to Hyper, it supports speeds up  to 3,800 MB/s and features a recycled aluminum case and a protective silicon sleeve. It measures 140 x 60 x 21mm (5.5″ x 2.4″ x 0.8″) and weighs 260 grams (9.2 ounces), and as far as I can tell, this model is passively cooled.

Orico is also planning to launch a USB4 SSD enclosure soon, and the company is running a Kickstarter crowdfunding campaign. The Orico enclosure has a fan for active cooling, and an aluminum case with a transparent lid that lets you see the SSD, if that’s something you care about.

It measures 131 x 50 x 14mm (5.2″ x 2″ x 0.6″) and has a list price of $169, but Kickstarter backers can reserve one for $119 and up. Orico expects to begin shipping the enclosure to backers in December, 2023.

The JEYI 40 Gbps USB 4.0 M.2 NVMe SSD enclosure may not come from a well-known brand, but it’s one of the cheapest options to feature the ASM2464PD controller, selling for just $75 and up at AliExpress.

This aluminum enclosure is said to support read/write speeds up to a theoretical maximum of 3,200MB/s and 2,700MB/s, but Liliputing’s Ian Morrison has actually recorded even higher speeds up to 3,803 MB/s read and 2,985 MB/s write on this model.

It’s available in Standard, Pro, and “Fan” models, with the basic version featuring a slightly smaller case, the Pro version sporting a slightly larger case with a keychain loop and a leather strap, and the Fan model adding a fan for active cooling.

Update: This article had originally included and Acasis enclosure that’s said to support 40Gbps speeds, but since it has an Intel JHL7440 Thunderbolt 3 controller, it should actually be a little slower, with theoretical top speeds up to 2,700 MB/s read and 2,800 MB/s write.

  1. The controller appears able to handle 4 gen4 SSDs, so why isn’t anyone making a tiny NAS from it?

  2. Please note most speeds are done on Apple that does have good speed ports. Always Note the word (theoretical), I bought a Acasis 40Gbps SSD like above without fan in Windows on Razer Blade 18 TB 4 port it got a write speed of only around 600mbps 2000 short of there quote. Again because most speeds quoted are from Apple computers. Its time they gave good Windows speed quotes. You also have to take into account of the port controller in your computer. It may be a TB 3 or 4 but the actual controller hardware pays a part in speed. Again the RB 18 laptop has a SD card slot the latest
    UHS 11. I also had a external USB 3 plug in one UHS 11 the laptop reader got a max 95mbps read but the USB 3 plug in got 158mbps. The card max read stated 160mbps = a wrapping 30% better. So as the saying goes its a suck it and see every time. Owe I had a 10Gbps enclosure before the Acasis it was reading and writting at around 1000Mbs that was nice for the price. Quoting 40Gbps I feel is a con? I hope you enjoyed and learned from my words. Happy computing.

    1. The notebook manufacturer is clearly at fault. As the standard becomes popular, manufacturers will have to improve the components (controller) because it will get a bad reputation. Your equipment has potential for the future.

  5. I didn’t think that there was already a wide range of devices using USB 4. In my opinion, the biggest difference between the current standard (USB4) and the older one (USB3.X) we will observe when many ports and components are integrated, e.g. 1 Gb/s LAN port, 2x DP 2.1 (type c), nvme drive, gpu etc.

    1. As you can see, the case has at bottom en top side holes made to let the air flow through with use of that fan, as it works in laptops.

      1. I was just making fun of the illustration that shows the direction the air is flowing.
