Hello Colin, I have a couple more screen shots showing the raw performance of both drives; the first using 512MiB as you suggested and the second with a larger sample and using the dd commands status=progress option to monitor for pauses. Also in the second ss, I performed the test on an iso file from the zfs file system. I did not see any pauses on the raw devices, but then I only saw momentary pauses (one second or less) on the zfs file. Regards, Colin.
