Just moved all ext. HD USB plots from a TR plotter to a Ryzen 3600 w/32GB memory for farming. Had a few TBs of space to fill. As an experiement, took a NEW Samsung 860 Pro 1tb, updated the firmware, and replaced the primary B550 MB OS nvme (PCI-E 4.0) with it, and put an old, old 860 EVO 500GB on a spare SATA MB connection. Started a plot on each. Each 9000 memory, 8 threads and started same time (just 2 min apart). Surely the 980 Pro will win against an old SATA ssd, right?
WRONG! EVO 5 hrs 25 min; 980 5 hrs 46 min. How could this be? Nvme against SATA and SATA wins!?!?
What I did notice, and to the 980s favor, was that it was barely doing anything, active time was a few % normally, where the EVO was a 30-40–50-70-80% pretty much always. So the 980 can do much more simultaneously. But it still astounds me that the SATA did BETTER time than the 980 single plot?
Any ideas? Am I CPU bound or ???
