Cable Matters 40Gbps USB4 Cable, 240W, 0.8m, Black | [8K@60Hz / 4K@240Hz Video, 240W Charging, 40Gbps Data] USB 4 Cable, Compatible with Thunderbolt 4, MacBook, XPS, Surface Pro

After finally understanding that the many 480Mbps USB-C cables I have purchased for my external Crucial X9 Pro SSDs were simply not capable of delivering the high speeds that the drives were designed for, I purchased these 40Gbps cables. Boy what a difference they make! Now data transfers at lightning speed (which is what I always wanted when I purchased the SSDs). My daily Time Machine backups, and monthly archives, now complete about 10X faster. I'd highly recommend these cables.

The cable is strong and appears to be well-made. Data transfers are as expected. I've used other Cable Matters products and they've always been reliable.

Top quality

I bought this Cable Matters USB4 cable to replace a shorter Thunderbolt lead in a desk setup that handles charging, external storage, and high resolution display output through a single connection. Physically, the cable feels reassuringly substantial, with thick insulation and well finished USB C ends that seat firmly without wobble. At two metres it strikes a good balance between reach and signal integrity, and it does not feel fragile despite supporting very high power delivery.In daily use it has performed exactly as intended. Laptop charging is stable even under sustained load, data transfers to fast SSDs are noticeably quicker than with standard USB C cables, and driving high resolution displays through a dock has been reliable. The main compromise is flexibility, as the cable is stiffer and bulkier than typical charging leads, which makes tight cable management slightly awkward. I have also found that compatibility can depend on the device rather than the cable itself. Overall, it is a well engineered, future proof cable that offers excellent value if you actually need USB4 performance.

Cable matters cables are usually very good, however I have had two of these cables and within a few weeks both of them started disconnecting with the slightest movement, which corrupted my external OWC 1M2 SSD. Thank goodness I had an up-to-date backup. I have now bought a quality Intel certified OWC Thunderbolt 5 cable at nearly four times the price, but you can't put a price on data integrity. I'm not going to risk getting this Cable Matters cable replaced as it is way too risky.

This is being used to replace a certified thunderbolt 3 cable that was a little too short. Replacement Thunderbolt cables have OTT pricing, so seeing that this (relatively cheap) USB cable claimed compatibility with Thunderbolt 3 and 4, I decided to give it a go.Happy to confirm that it it working fine with my Caldigit TS3. Cable is fully powering laptop and feeding 2 x 4k monitors at 60hz, a camera, external storage, and a keyboard without complaints.Note that this cable is thicker than average due to the power rating.

Works great and extremely fast for transferring data.The cable is quite flexible but feels a little chunkier than your charger cables for example.Good value for money Vs competitor brands and cable matters usually provide the official certificates for all there cables.Went with black and it's your bog standard silicon looking cable and feels relatively durable.

This is the real deal. If you need super fast charging, this cable does the job. Reassuringly thick for fast and stable connection.

Nice Product

Can't believe thunderbolt cables are so cheap now. Using it to connect my MacBook Pro with Mac Studio. It works perfectly, Mac reports connection speed as 40Gb/s.
