It does go to zero sometimes, but just for a few seconds. Then it picks back up to around 275 MB/s again. The amount of time this transfer is taking does not match that write speed sadly. The read speed from the source drive matches the reported transfer speed as well. I wonder what causes that difference?

I'm new to Unraid and setting up my first server currently. After adding two drives to my array and formatting them to XFS, I started transferring data to them from an unassigned drive which is connected to the server directly via SATA, which is formatted as NTFS. I don't have parity or a cache enabled and want to transfer around 18tb of data to the array. For the transfer I used the native file manager and i am copying, not moving, them over. The problem is that the transfer speeds are very slow, almost always ranging between 20 and 50 MB/s, occasionally jumping up to around 180 MB/s for a few seconds. I know that my drives are all fully functional, as they've been running totally fine on the windows machine they were on before, with read and write speeds well over 150 MB/s. So what is going on? Am I doing something wrong? I'd understand the slow write speeds if I had a parity disk, but that's not the case. There's also plenty of free memory, although my CPU seems to have suspiciously high usage. I'd appreciate the help! I attached diagnostics and some screenshots for clarification. mono-diagnostics-20250421-1316.zip
