Hello,
I am experiencing poor transfer performance between two P41 Plus drives in Ubuntu. Have tested moderate sized files (7GB) and larger files (50GB); results are the same. After a quick burst, R/W significantly declines.
Please see the below iotop results as a proxy during a transfer of a folder of 7GB files. The burst lasts for about 5 seconds and then significantly declines.
Here is the drive information for the two:
