Ok thank you. I've got 5TB left of this large initial load (~24h based on current speeds). Guess I should have waited until after I had parity before I started. I'll do a test after this transfer is done and I get a parity sync and see if my speeds increase.

Here is the .zip file posted. smnas-diagnostics-20240115-1206.zip

@JorgeB Which of these log files would be most useful?

@itimpi yes that is what I mean. I have parity on the array but have paused the parity check until initial transfer is complete. @Kilrah I have already enabled "reconstruct write" in the disk settings page. if this is what you are referring to. I guess to summarize my initial question is getting 50MBps the most that I will get or will I get better speeds not going through a host machine vs using iScsi to transfer directly in unread in the shell with mc.

I have paused the pairity job until I have the initial data load complete and am still around 50MB from the VM on the server to array. Is that the best performance I will have for now?

New user to Unraid as I'm transitioning from a dead synology unit. Current unraid setup 4x12TB 7200RPM using 1 as parity in my array. I have my backup data from my synology temporarily on a 24bay IBM storage chassis. I was able to mount the storage chassis using iscsi on a second server then use smb to the unraid share. This worked but provided somewhat lackluster performance averaging around 40MB/s. (1Gb network with 10k RPM hard drives to 7200RPM Unraid Drive) I have a cache drive ready for unraid but am not using it until I complete moving my large data moves. I'm getting ready to move about 15TB of data now and would like to know if I would be able to get better transfer rates by connecting to my storage chassis directly from my unraid host and performing a data copy to my unraid share. I have tested and am able to use iscsi initiator to establish a connection and mount my storage chassis as a read only disk device. In MC I can then navigate to "/mnt/disks/v3700/data" this is the folder I want to move to my unraid array. This folder would have to fill and spill over to a second drive in my array as my share is using high water allocation. Would this be classified as a disk to share that I read is not advised? What is my best path to efficiently move this 15TB folder?
