Your Video is very Misleading!!!! Generally In Flash storages, Higher the capacity means Higher Read/write speed. You are comparing 8GB, 16GB drive to 32,64, GB Pen drive. Which is Unfair comparison. You should compare All brands of pendrive on 64 GB!!! then the Comparison will be fair. I think those Kinston pen-drives that you have are Fake. That's why they are performing poorly. I have a 256GB Kinston Data-Traveler Kyson USB 3.2 Gen 1 pendrive. I tested it and I've got 250MBps Read speed/80MBps Write in Crystaldisk Mark I also have 128GB Sandisk Ultra flair In Benchmark 165MBps Read/56MBps write But in terms of Real life DATA transfer Sandisk is Better in Writing almost 40 to 35 MB/MBps In Kingston it's around 30MBps But In terms of Read speed Kingston Kyson wins In real life DATA transfer I have got 265MBps in Read speed on Kinston Kyson And Sandisk is around 160-132 MBps in Read Speed. Sandisk Ultra flair was burning Hot 🥵 🔥 during test On the other hand!!! Kinston was Warm but heat was bearable
