I paid some extra money to finally get a good USB stick that might not have false marketing around it, like 99% of the sticks on market. From the advertised 900MB/s speed, I managed to push only 110. Before you ask - My PC slot supports USB 3.2 2x2 that normally goes way faster on data transfers.

Not sure if I got a faulty stick or something, but at this point I’m getting real tired boss

I use nvme enclosures. Very fast and very hot. I also got some fikwot ssd based flash drive that’s about the size of a common flash drive. I’ve seen it sustain around 500MB/s very well. Some type of metal enclosure. At this point I’m probably only buying enclosures and small NVME drives or USB sticks where the enclosure is metal and reviews seem solid saying it’s hitting SATA 3+ speeds sustained well
