OWC 28-Inch Thunderbolt 4 and USB-C Cable with 40 GBPS Data Transfer, 240W Power Charging and 8K Video Capability (Black)

Not all cables are created equal. I’m using these with fast SSDs and an M3 Ultra Mac Studio, and they perform flawlessly. The build quality is excellent, and transfer speeds are consistently reliable. Couldn’t ask for more from a cable. Definitely a worthy buy—I’ll be getting more in the future!

Hooked up a 4TB external SSD hard drive. Used the cord that came with the drive. Noticed my speed test was no where near the capabilities of the SSD or my computer. This was a great choice. If your computer and external drive can utilize this cord, my speed test almost tripled. The length is great as I do not need a lot of cord to wind out of my way. Connections are tight. Great value for the speed return.

High quality and just works great!

Works great and supports full speed. Wish it was less expensive but better quality than price I guess.

Excellent quality

Needed an T-4 cable for a new Mac Mini and this was a pretty good value. It seems to work as expected. I can't measure the sped of the cable though. I've generally been happy with QWC products over the decades.

There aren't much thunderbolt 5 devices out yet, but this thick cable is future proof and ready to handle upcoming devices. This cable is not as cheap as some of the other cables you can find online, but, it is from a local American company with a strong reputation. Many of the other "American" branded companies in the accessories market are like shell companies of a dozen American employees or less that outsource everything else overseas. OWC employs hundreds of US workers.You get what you pay for, and in this case I think it's a high quality cable from an American company.I noticed that even in apples to apples comparisons (such as fast charging a device only capable of 40 watts) this cable performs marginally better than other cables. Like 40.7 vs 41.7, it's not much, but it's interesting to note. I guess maybe it's because of the quality of the cable and the requirements of the thunderbolt 5 standard let it squeeze just a little bit more into devices?Don't expect significant gains unless you're using an actual thunderbolt 5 connection, but you can expect this to reliably max out any device you'll ever buy and beat any cable on the market.
