gerard6110 Posted January 12, 2020 Share Posted January 12, 2020 (edited) Copying over the 1GB network from the array (normal 2.5" drives) of server 1 to a windows PC with SSD with 1 1GB switch inbetween reaches the 100+ MB/s - OK. Copying from the SSD cache from server 1 to the attached (unassigned device) USB3 disk only reaches 25 MB/s - NOK! Copying from server 2 to the same USB3 disk does reach 100+ MB/s, so the USB3 disk is not the bottleneck. So why is copying from the SSD cache only 25% of the array speed, where reading from the cache is much faster than from the array? Edited January 13, 2020 by gerard6110 Quote Link to comment
itimpi Posted January 12, 2020 Share Posted January 12, 2020 Are you sure you plugged into a USB3 port rather than a USB2 one? Quote Link to comment
