Cable Matters [USB-IF Certified] 40Gbps USB 4 Cable - 3.3ft, Supports Up to [8K@60Hz / 4K@240Hz Video, 240W Charging, 40Gbps Data Transfer] USB4 Cable, Black, Compatible with Thunderbolt 4, MacBook

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.

Everything about this cable is great except how stiff it actually is. Would have preferred it to be a bit more flexible but perhaps that would have compromised its quality and durability. Use these cables together with NVMe enclosures. Transfers are fast and reliable.

Works great, using it for a DAC because the original cord was not long enough. Wanted high quality cables for my setup and this has been a good pick.

I am using 2 of these in a dual USB4/40Gbs windows raid-1 configuration. My motherboard is the MSI X870E Carbon Wifi. The enclosure is the OWC Express 1M2. They are working great, no speed loss.Samsung 990 EVO Plus 4TB RAID-1. I picked these cables because I didn't need Thunderbolt and yet the cable is USB4 certified.CrystalDiskMark:Read SEQ 1MiB (Q= 8, T= 1): 6882.326 MB/sWrite SEQ 1MiB (Q= 8, T= 1): 4990.122 MB/s

Very fast and strong

Got a lightweight "click" seating both ends of this cable.Feels looser than I prefer, I'm used to a definitive snap retention with constrained wiggle.Using this for an external NVMe enclosure, and T3/USB that had disconnection issues with a prior cable.The price was right for a known legacy brand, with good throughput and so far no dropped connection of my drive.I'll update with any changes.

Great length, thick cable, solid qualityI haven’t bench tested but it certainly seems like this cable is the fastest transmitting cable I own for file transfers etc.Works for charging as well. Great overall quality

Amid a sea of 2.0-only-capable charging USB-C-to-C cables, this is a good solid certified C-to-C cable that seems to deliver on its promise of speed. Admittedly, I currently am only only to use it at up to 10Gbps speeds due to available equipment; but it made my USB-C 5GbE dongle actually stably connect to both my laptop and desktop and provide rated ethernet speeds on my 1/2.5/5/10GbE-capable network.
