Cache drive speeds slower when downloading to it

When I download a file via SFTP directly to a share mapped as a network drive in Windows, that uses the nvme cache drive, the speeds max out around 600Mbps. However, if I download the same file to my desktop, via SFTP, I get 1Gbit down just fine. If I then copy it to the same share, I get the full 1Gbit LAN speeds too.

 

My router is a UDM, so it should be more than capable of handling 1Gbit. It's CPU usage while downloading directly to the cache is 17%. My PC has a 5900X, currently sat at 2% usage, so I don't think the bottleneck is there either. My Unraid server has an i5-11400 that isn't sweating either.

 

If everything works over LAN, why is it suddenly slower when downloading direct to cache?

What is the share name, and what do you mean by "download directly"

 

Also, disk 3 and the unassigned 5TB drive should have their cabling reseated to them (continual resets)

 

The share is multimedia. By directly, I mean download a file from a remote server, via an FTP client on my PC, with the multimedia share as the destination (as it's mapped as a network drive).

 

Thank you for the warning on the drives. I am aware of those, I believe it's a result of the crappy pci card I'm using. I have an LSI SAS 9210-8i on the way.
