Gigastone Z90 [2-Pack] 32GB USB 3.1 flash drives have proven unreliable for my needs. They worked for about a week, then suddenly one stopped working, and a few days later another. So far, two out of four aren't working the way I planned. I use them as a USB drive for my QIDI 3D printers. Update: 05/22/2021. Currently, three out of four no longer work properly. Each served a desired purpose but ultimately failed.
