Review on 🔌 THKAILAR USB Flash Drive 3.0 - 128GB, 256GB, 512GB Thumb Drive for Business Traveler - External Storage Data, Swivel Design (128GB, Black) by Mac Sterling

I really want the advertised speeds to be actual average speeds rather than "PEAK". The actual read speeds I tested (see around 3MB/s) aren't very good. (Still better than the 50-100 KB/s I tested recently on another unnamed brand). In fact, the test ended in less than 5 minutes instead of 1/2 hour I guess if you really need good writing speed it's better to use a proprietary SD card and a USB 2.x/3.x adapter.
