Review on 🔌 TOSPLUS 5Pack 16GB USB 2.0 Flash Drive: Reliable Thumb Drives with Zip Drive Functionality by Josh Dyer

I tested all 3 discs by writing 10 random 3GB data files and checking the checksum. 2 have proven to be good - performance isn't great, but it's close to spec and they seem reliable. The second started well, then stopped. Some parts of it are bad - writes slow to < 1MB/s and data comes back corrupted. I washed and tested several times and the results kept getting worse. every time. It's toast.
