As a laptop reviewer, I regularly test accessories that enhance the user experience. Most of the time, these are docking stations or monitors. But I sometimes come across something completely different that changes the way I use a laptop. A case in point is the HyperDrive Next USB M.4 PCIe enclosure.

It’s an interesting device. This enclosure has one use: to house SSDs and PCIe modules for data storage. With the right component, it effectively becomes a fancy flash drive. One that ensures speedy file management and, according to the company, the capacity to house machine learning accelerators. 

Why we like it

By far my favorite aspect of the enclosure is its speed. The HyperDrive is built to deliver real-world performance for professionals who frequently work with large files. To see how the accessory performs, I ran a series of tests to measure its data transfer speed.

For this scenario, I used the Acer Swift Edge 14 as the central computer. This laptop has a Thunderbolt 4 port off to the side. Inside the enclosure was a 4TB Samsung 9100 Pro NVMe M.2 SSD. The key numbers to watch for regarding file transfers are read speed, which measures how quickly a computer can access stored data, and write speed, which measures how quickly a computer can save new files. 

Once everything was set up, I ran these tests with CrystalDiskMark, an open-source benchmarking tool that evaluates solid-state drive performance.

With this setup, the Samsung SSD achieved read speeds of roughly 4,000 MB/s and write speeds of about 1,300 MB/s. Those are great numbers. Accessing files felt instantaneous. It took no time at all to open the movie I stored inside the drive. The read speed also shows that the enclosure isn’t restricting the drive. It’s making full use of the Thunderbolt connection. Writing large files is equally impressive, letting users save big files fast.

To put the write speed into perspective, here are real-world file transfers that I performed. These numbers show that the HyperDrive enclosure supports fast large-file transfers, whether they’re movies, video games, or multi-gigabyte media libraries:

  • 10GB movie: 25 seconds
  • 20GB movie: 50 seconds
  • 22GB movie: 52 seconds
  • 98GB video game: Four minutes and nine seconds
  • 50GB Google Takeout files: One minute and 36 seconds

Something to keep in mind is that performance can vary. It depends on certain factors. For example, if your laptop has a Thunderbolt 5 port, you can expect even faster speeds.

The enclosure has a pretty cool design, too, combining a sleek aluminum form factor with rugged durability. When placed in its silicone sleeve, the accessory achieves an IP55 rating, protecting against dust and small splashes of water. Along the enclosure body are a series of ridges. These increase the overall surface area, helping to release heat into the air. Customers also receive thermal pads that sit on top of the SSD to absorb more heat.

Installation is very straightforward. Pop open the top, then slide the SSD or PCIe module into the receiving slot until it clicks into place.

Who the drive is for

Typically, SSDs like the Samsung 9100 Pro need to be installed in a PC to be used. This enclosure effectively turns that drive into a USB stick, like the kind you buy at an electronics store. HyperDrive’s accessory is meant for professionals who own high-capacity, high-speed storage and need a way to utilize it. I recommend the device to videographers, content creators, AI developers, and even multimedia archivists looking to put their SSD stick to good use.

The enclosure supports multiple M.2 sizes, including 2230, 2242, 2260, and 2280. On the front, the HyperDrive Next features two Thunderbolt ports: one for data transfer and one for external power-in. Certain high-performance NVMe SSDs may require an external power source to maintain peak read and write speeds.

Using the second port doesn’t boost speeds. I tried this approach, and the enclosure maintained the same high speeds mentioned earlier. If you need the extra input, it’s there, but from my experience, it’s not essential.

Who should look elsewhere?

The HyperDrive enclosure is not for the average user. By itself, it does nothing. You’ll need an NVMe SSD to make it work, and at the time of writing, average SSD prices have shot up. The 4TB Samsung 9100 Pro that I used for testing currently costs over $780. Granted, there are plenty of SSDs on sale that are much cheaper than the 9100 Pro. Still, you will need to pay extra.

For most people, I recommend sticking to a basic flash drive, external hard drive, or cloud storage to manage files. The HyperDrive is a premium accessory built for power users.

ZDNET’s buying advice

The HyperDrive Next USB4 M.2 PCIe enclosure is on sale for $200. Buyers should carefully check system compatibility before purchasing. A key limitation is that it requires a computer with a Thunderbolt 4 port (Thunderbolt 5 is fine). Without this port, the enclosure will not work. This limitation applies to both Windows 11 PCs, Macs, and iPads — yes, the accessory works with iPads.

If you’re planning to use this accessory with Apple hardware, make sure your Mac is running MacOS 12.4 or later, and your iPad is running iPadOS 13.4 or later.

A new class-action lawsuit, filed on Monday by three teenage girls and their guardians, alleges that Elon Musk’s xAI created and distributed child sexual abuse material featuring their faces and likenesses with its Grok AI tech.

“Their lives have been shattered by the devastating loss of privacy, dignity, and personal safety that the production and dissemination of this CSAM have caused,” the filing says. “xAI’s financial gain through the increased use of its image- and video-making product came at their expense and well-being.”

From December to early January, Grok allowed many AI and X social media users to create AI-generated nonconsensual intimate images, sometimes known as deepfake porn. Reports estimate that Grok users made 4.4 million “undressed” or “nudified” images, 41% of the total number of images created, over a period of nine days. 

X, xAI and its safety and child safety divisions did not immediately respond to a request for comment.

The wave of “undressed” images stirred outrage around the world. The European Commission quickly launched an investigation, while Malaysia and Indonesia banned X within their borders. Some US government representatives called on Apple and Google to remove the app from their app stores for violating their policies, but no federal investigation into X or xAI has been opened. A similar, separate class-action lawsuit was filed (PDF) by a South Carolina woman in late January.

The dehumanizing trend highlighted just how capable modern AI image tools are at creating content that seems realistic. The new complaint compares Grok’s self-proclaimed “spicy AI” generation to the “dark arts” with its ease of subjecting children to “any pose, however sick, however fetishized, however unlawful.”

“To the viewer, the resulting video appears entirely real. For the child, her identifying features will now forever be attached to a video depicting her own child sexual abuse,” the complaint reads.

The complaint says xAI is at fault because it did not employ industry-standard guardrails that would prevent abusers from making this content. It says xAI licensed use of its tech to third-party companies abroad, which sold subscriptions that led abusers to make child sexual abuse images featuring the faces and likenesses of the victims. The requests ran through xAI’s servers, which makes the company liable, the complaint argues.

The lawsuit was filed by three Jane Does, pseudonyms given to the teens to protect their identities. Jane Doe 1 was first alerted to the fact that abusive, AI-generated sexual material of her was circulating on the web by an anonymous Instagram message in early December. The filing says she was told about a Discord server by the anonymous Instagram user, where the material was shared. That led Jane Doe 1 and her family, and eventually law enforcement, to find and arrest one perpetrator.

Ongoing investigations led the families of Jane Does 2 and 3 to learn their children’s images had been transformed with xAI tech into abusive material.
