Hi, I needed to zero out my hard drive because one of my nodes has become unstable. To this purpose I used coreutils dd with the following command line arguments
dd if=/dev/zero of=/dev/mmc... status=progress and I noticed how slow this program is in doing the job. So I tried a couple of different settings, like bs=1048576 oflag=direct but without significant improvement. The results are always the same... around 25 mb/s. Then I remembered this little benchmark I write not so long ago, please do have a look at it, it won't destroy your drive. I included the results obtained by running the benchmark on the computer I'm currently working on, so you can compare them to your own. Hope that one of you feels inspired enough you to pick up the dd source codes and finish the job. Best regards, Mischa Baars.
