If you don't understand a cmd don't do it!
by GPGAgent from LinuxQuestions.org on (#5C6J3)
I was checking an Amazon review for a Kingston USB stick. A lot of 1 star revies went on about how slow this particular one was, so I ddg'd how to check the speed of a disk, and found quite a few examples, mainly using dd and /dev/zero for the data.
Then I found you could use fio
Looked to me till I found this https://86kanthraj.medium.com/linux-...s-631f2c286354
Linux FIO Broke My OS
It wasn't fio that broke his system, it was his lack of understanding that using /dev/sda isn't good practice.
Not content with destroying one server he went on to run the same command on many others, the tech support guys who gave him the command said 'it was a minor mistake'.
Read the article, the ebst bit is the guy who ran the command said it was really hard to find any answers on what they did!
Should have come to LQ!
