That's interesting. I have a Samsung 990 pro bought on Amazon and have the random lags. I've only noticed it in the terminal, so I figured something else may be the culprit. Never went to 15 secondes, but it can be around 1s.
The Samsung Magician app on Windows reports it as "genuine" and it was able to apply two firmware updates. The only thing it complains about is that I should be using PCIE 4 instead of 3, but I can't do anything about that.
I have been able to fix these random lags by doing multiple full disk reads. The first one will take very long, because it will trigger these lags. Subsequent ones will be much better.
The leading theory I have read is that maintenance/refreshing on the ssd is not done preventative/correctly by the firmware and you need to trigger it by accessing the data.
I'm going to try that, but I have little hope since this happened ever since the drive was brand new.
