Review on 💻 THKAILAR 128GB USB Flash Drives - Dual Port OTG Memory Stick with USB and Type-C Compatibility for Android Smartphones, PCs, MacBook Pro (Silver) by Joe Michels

I really wish the advertised speeds weren't "PEAK" but true average speeds. Actual read speeds I've tested (see photo) are 100MB/s, while write speeds start at 50MB/s but drop by 3MB/s - not great. (Still better than the 50-100 KB/s I recently tested at another unnamed brand). In fact, the test was completed in less than 5 minutes, not half an hour. If you really need good writing speed, it is better to use proprietary SD card and USB 2.x/3.x adapter.
