No probem, we will just have to wait and keep our fingers crossed. Thanks for all the help!

Hey JorgeB, Sorry to jump back in on this old post but did you ever hear anything back about this issue?

Thanks for all your help with this👍

Same for me. I paused and then unpaused and the transfer went to normal speed. That is a very strange one!😅

So I tried the same but for me it did not work. It seems to have slowed down copying a single file to less then 100MB/s and then just under half that when copying 2 files from different disks. I then removed the text from SMB extras and then it speeded up again but still get half the speed when copying 2 files.

Definetly much faster for me when running your test scenario. Thanks for looking into this for me. I will use the web terminal whenever i need the extra speed as this seem much faster.

Thanks for making LT aware. I guess we will just have to see what happens going forward with updates. I might give it a try with NFS shares ans see if that makes a difference l.

Diagnostic file attached. Thanks for looking into this nsd-unraid-diagnostics-20250830-1933.zip

Based on the results below it does not look like the controller is the problem. Not sure what else to try to see what the isue might be

So I ran a bandwidth test using diskspeed on my controller. The rsult was "Current & Maximum Link Speed: 8GT/s (PCIe 3) width x2 (1.97 GB/s max throughput)" Would 6x Sata 7200rpm HDD's bottleneck this?

So just tried using disk shares and got the same result. I have added two screenshots to show the difference in speed and as I said both files are on different drives in the array.

Thanks for the reply. I will give this a try and see if anything changes. Im also thinking maybe it is my M.2 NVME to 6x SATA adapter that is a bottleneck.

First I want to apologize for how much of a beginner I am😅. I have setup an array of 6 disks, 1 of which is a parity drive. When copying 2 single large files from the array to my windows machine I notice the speed is halved even though the files are copying from 2 different drives in the array. I have a 10Gbe network card on both ends. So I will be getting about just over 200MB/s and then as soon as i start copying another file I notice each file copies at just under 100MB/s. I would understand this if they was copying from the same drive but I thought this wouldnt be the case as they are copying from 2 different drives. Any help with this would be much appreciated.
