Reliable USB-Flash Drive

Hello! If this is the wrong place to ask this question, please let me know and kindly push me into the right direction :)

So, I am looking for a USB Flash Drive. I do not care about form factor, storage capacity or speed, since the file on there will only be a few bytes.

BUT, I need it to be reliable. I've had many USBs not working / breaking out of nowhere, without any impact from outside. They just simply stopped working.

So, what are your recommendations for a really reliable USB flash drive?
