Transfers speed starts at what is to be expected from my HDD in the array (120 MB/s) but than slow down to 30 MB/s and stay at that speed for the rest of the data transfer.
Also copying between separate SSD pools behaves in this way. Starts at 400 MB/s and after 20 gigabytes copied the transfer stays at 22 MB/s.
This behavior is observed with docker/VMs enabled and disabled.
I have already tried TRIM.
Any ideas what causes this?
