I have started the process over from the beginning. It seems to respond well to obs=4M as the write speed has gone from 3.7 MB/s to 28.2 MB/s, which is about the same as where it was with obs=1M. It should take a couple of days to complete this write process.
The WD drive that I have, which is connected to a separate USB2 port, showed a write speed of 27.5 Mb/s. I am using: dd if=/dev/zero of=/dev/sdb obs=4M status=progress The read speed was faster, of course. name=Matthew%20Campbell&email=trenix25%40pm.me -------- Original Message -------- On Jun 9, 2020, 2:39 AM, Nicolas George wrote: > Christopher David Howie (12020-06-08): > I'd suggest simply adding > "status=progress" which gives you a summary every > second including bytes > written, elapsed time, and average transfer rate.
