You should mention very clearly which Raspberry Pi board you're using. I'm not sure if CPU throttling can affect I/O but if yes then it might also matter if you use a good case or use active cooling or heatsink.
Also, which OS version did you use? What Linux kernel version?
I'm more interested in longevity tests and industrial grade microSD card performance.

- geerlingguy 7y agoRaspberry Pi 4, latest Raspbian Lite image (2019-07-10 with kernel 4.19), and did apt-get update and upgrade prior to test and rebooted, official case with Fan modded in [1] to ensure it does not get anywhere near throttling.

And everyone asks for longevity tests and industrial grade performance, but I always answer the same: I have had four Pis running almost continuously (99.9% uptime, occasional reboot for updates) for 3+ years, and have used the same set of 6 Evo+ cards for 3+ years now, and have never had any problems with corruption in any of those cards. I also run a Kubernetes cluster with 4 Pis (see www.pidramble.com) from time to time (right now it's running), and I have never had a corruption issue either. The main thing I attribute this to is the fact that I'm using reliable, quality power supplies (either Pi Foundation official supply or some other name brand or good PoE power supplies that support at least 2A).
