I just finished putting my NAS together and have really been enjoying unRAID so far but I am having issues. At first, I was trying to transfer my data from Windows 11 to the NAS just using File Explorer. After some Googling, I found out that isn't the best option so I then tried moving all the files to an external HDD and using Krusader. It still acted similar to File Explorer, it would start off pretty fast and then almost grind to a halt. I am now trying to use rsync and I'm getting similar issues. It'll start off around 1000 Mbps and then drop down to single digits. Any help is greatly appreciated!

Please post the diagnostics.

And this is fine.

It starts off fast because it uses 'extra' RAM to cache data as it is received.  As soon as that available RAM is full, the transfer speed will drop to drop to that of the read/write of the underlying hardware involved. 

 

Next parameter is the size of the files being transferred.  Because of the overhead involved in the file creation process and the storage of the file system information, writing large numbers of small files is slower than a smaller number of large files. (The read/write heads of the harddisks involved are constantly in motion between the file tables area and data areas on the disks.) 

 

A third parameter, if you are writing to User Shares, is the extra overhead of the User Share software.  (User Shares added another layer to the read/write operations.  It seems to have the greatest impact on write side of the equation.)  This overhead can be eliminated if you write to Disk Shares instead.  Of course, this means that you will have to analyze and specify where that files are being stored if you want to access them via User Shares later.
