I really want the speeds advertised to be not "PEAK" but true average speeds. The actual read speeds I've tested (see photo) are 100MB/s, while write speeds start at 50MB/s. but the drop to around 3 MB/s is not big. (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.
