Review on 10 Pack 8GB USB 3.0 Flash Drives - Mini Thumb Drive Bulk Multipack Memory Sticks 📦 - Fashion Pendrive - Metal Pen Drive Bulk Zip Drives - Red Jump Drive Data Storage by FEBNISCTE by Tyler Gannamani

So far I've had two of these drives that were so slow I think they're two USB devices pretending to be USB3. I use them as hard drives for Raspberry Pi computers so if they are slow, the entire computer is unusable. The three working computers have been fine so far, but having two of questionable quality makes me uncomfortable storing anything valuable on those drives.
