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.
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.
