Yes, my experience is that USB 2.0 **Flash** Drives are very slow. There are apparently some that are fast, but any that I've tried have only been about 2-10 MB/second. When BB plays a file, it might access about 24 MB of audio files, so that's up to 12 seconds just to read the data, likely longer.

Newer USB 3.0 Flash drives report 10x faster read speeds (real-world tests have found 3-5X speed increase*), for example this one at 100MB/second.

We are testing some of these new flash drives to see if they work well with BiaB. As mentioned, your PC would need to support USB 3.0 for this to work. If someone has one of these fast 3.0 Flash Drives, please let us know their results with using it to run BiaB.

*"While you won’t see a tenfold increase in the transfer speed from USB 2.0 to USB 3.0 in real-world use, USB 3.0 is fast—about three times faster than USB 2.0 with a spinning hard drive, and three to five times faster with SSD."


Have Fun!
