Just thought I would sign up to mention that this is still an issue 2022. I usually do not spend this amount of money on a USB stick since cheaper ones have worked just fine in the past. Me, and I am guessing most other people here have used other USB sticks in the past. So to pretend we can’t make a decent judgment on whether something gets too hot is not fair. I think this is also more justified after several people mentioning it gets so hot that parts are melting off. Someone earlier on in the thread also did a pretty elaborate test to check.
I bought two and will have to throw both away. It’s not worth potentially damaging the computer parts over. Fortunately I do have two others not from Sandisk for a third of the price that work well.
Recommend Sandisk to own up and fix it since these days people will find out when word spreads online. Owning up to it after will gain respect. Trying to ignore and hide it will not.
