Cable Matters [USB-IF Certified] 40Gbps USB4 Cable, 3.3ft, Black

This is a very effective product. Although it also functions for high speed video signal, it can also facilitate very fast charging, if you pair it with a certified fast charger. If you want a reliable product, whether it is a cable or a charger, select one that says "USB-IF Certified" or something close to that. It may cost a dollar or two more, but it is worth getting a reliable fast product. Many, many products in these two categories advertise very fast results, but show reviews saying they did nor perform as advertised. Buying a certified (from a 3rd party) gives you more assurance it will live up to its advertised speeds. This products exceeds expectations. On a separate note, the cable is much stiffer than your typical cable, likely due to its ability to pass more power or video through than older generations of cables. If you don't mind the stiffness, you get a very high quality product - the best performing we have found so far.

There was a time, perhaps 20 years ago, when it truly didn't matter which USB/HDMI cable you bought. Brands like "monster cable" overcharged uneducated people to a disgusting degree, while the rest of us laughed and bought the cheapest possible cables which performed identically. ...well, those simple days are gone now. With the advent of 2K/4K/8K, not every HDMI cable is the same anymore. And with data transfer speeds evolving so quickly, USB-C cables have become one of the most confusing tech items for consumers to buy. So before buying a premium cable like this, ask yourself: -Do you actually need USB4 data transfer speeds (40 Gbps)? Like, are you frequently using an external SSD with USB4 capability? If not, you probably don't need this. -Do you only need this cable for something like a USB-C monitor? Look for an uncertified USB4 cable capable of 20 Gbps, or depending on the monitor you may only need USB-C 3.0. It will be cheaper than this cable. With that being said, if you actually do need the crazy speed of a cable like this, then spare yourself the time and frustration of cheaper brands. After much trial and error with many different cables, docks, hubs, etc; I have decided the Cable Matters brand is what I'll be looking for from now on when I *actually* need a super high-speed cable. They don't lie about their claims. If it isn't a certified cable, they will say that in the description and give you real speeds. This cable does what it claims: it transfers data at 40Gbps. That's what I needed for my case, and it's been working flawlessly for many months now. No negatives here.

High quality USB4 cable with a genuine USB-IF certification that you can check for yourself on the USB-IF website by searching this cable's model number (201304). Both USB and Thunderbolt compatible. I have used mine for data transfers with a portable SSD and for super fast charging my phone. Feels thick and sturdy in hand but it is slightly stiff. I also like the clearly labeled wattage and data transfer rates. Thumbs up from me.

Great build quality, solid connections, and USB-IF certified for peace of mind. I tested it with a Samsung 990 Pro 4TB NVMe SSD in a USB4 enclosure, and it delivered full USB4 speeds (see attached benchmark). No signal drops, throttling, or compatibility issues. Just works — and works well. ✅ Fast ✅ Reliable ✅ Certified ✅ Worth it Highly recommended if you're doing anything high-performance over USB4 or Thunderbolt.

In a sea of scam/false-advertising cables, I can say for the most part that this cable is actually what it claims to be. I tested a WD BLACK P40 NVMe Game Drive with CrystalDiskMark, and it reaches the speeds I'd expect to see. It was plugged into a SS10 (SuperSpeed 10) on my laptop. The other cheaper (and admittedly better looking) cable I purchased and returned before this one claimed to be able to reach USB 3.2 2x2, yet when tested was half of the speed I expected and was advertised. I have not tested the charging capabilites yet but I am definitely not going to use the full 240W, but since the speeds were as advertised I'll trust this can handle charging my iPad and laptop on occasion. Since this is a USB4 cable, it can handle pretty much every USB gen under the sun (as of this review). Physically, although it isn't braided or anything, it is sturdy and I expect it to last for a long time. TLDR: If you need a super fast and high quality cable, spend the extra $5-$10 over the obscure and randomly named brand cable that is false-advertising, and go with this one. It'll cover everything you need.

Does it's job

My new laptop was not working properly with my EGPU. I didn't think it was the cable I had, because it was working perfectly with a Dell XPS running a gen 8 Intel processor. But for whatever reason, my new laptop (Framework) with gen 13 would constantly lose the connection. Through trial and error, I decided it must be the cable. I really wish I had just tried a new cable at first because that was it. This cable is great, immediately fixed my problem. There is quite a variety of quality out there, and this brand had a good reputation so I gave it a try. Anker but also be a good choice. I would not recommend getting a cable any longer than this one for EGPU. For a regular docking station, it should be fine to go longer. I also would not recommend getting a no name cable, you just don't know what you're getting these days.

Just what I needed. I had tried a cable from the local brick and mortar store, but it didn't surpass the USB 2.0 speeds. I'm using this for an older NVMe drive in an external enclosure, so my speeds aren't as impressive as other reviews. I didn't need a 40Gbps cable, but it was less expensive the many of the 10Gbps cables. So I'm ready for USB 4 in the future. I also really like the soft jacket on this cable, flexible without feeling like it's going to break.

I'm incredibly impressed with the Cable Matters [USB-IF Certified] 40Gbps USB C cable. I've been using it for a variety of tasks, and the speed is absolutely phenomenal. Transferring large video files that used to take minutes now happens in seconds, and it's made my workflow so much smoother. The 40Gbps data transfer rate isn't just a number on the box; it's a real, tangible performance boost. Beyond the speed, the build quality is top-notch. The cable feels durable and well-made, and the connectors are solid and secure. The USB-IF certification gives me peace of mind that this cable meets a high standard for both safety and performance, which is a huge plus. It also supports high-power charging, so I can use it to quickly charge my laptop and other devices without any issues. This cable is a fantastic value for the performance and quality it delivers. It's truly a future-proof accessory for anyone with modern USB-C devices. I highly recommend it if you're looking for a reliable, high-speed, and certified cable that won't let you down.

Asombrosa la velocidad de transferencia vs un cable comun. Soy DJ y la diferencia de dewsempeño que encuentro con el uso de este cable es mucha

Excellent cable qui fonctionne à 40gbps.

El producto es, acorde a lo que la marca acostumbra, bueno. El tema es la rigidez del cable, es ancho y bastante rígido, lo cual resta maniobrabilidad

Utilisé sur un moniteur (Gigabyte M27UP) doté d’un hub interne, il permet l’affichage (display port alt mode) à 144 hz en 4K ou 320hz en 1080p sur un MacBook Pro M4, tout en faisant la connexion avec deux d’ongles de clavier et souris sans fil et une paire d’enceintes usb, sans sourciller, et la puissance (power delivery) fourni par l’écran est pris en charge sans problème. La seule limite de ce câble, c’est les périphériques qui y sont reliés. On regrettera juste que comme tous les câbles de ce genre avec des specs très avancées, il est assez rigide, donc évitez d’en prendre un vraiment trop long par rapport à vos besoins.
