I'm still using a Supermicro X7SPA-H with an Intel Atom D510 and 4gb of Ram, I am only using it as NAS to stream data, not using any addons, such as dockers, plex or anything.

 

I am in the process of upgrading from 4TB to 8TB drives and I want to add an SSD cache drive as well.

While moving with unbalanced files from one drive to the other in order make space to change to XFS (still on reiserfs) I noticed the slow transfer speeds starting at 20 MB/s but then dropping to 10 MB/s. I am aware during the copy process the parity is updated as well. The last paritiy check was averaging 50 MB/s.

 

I was wondering what performance improvement I could get if I would switch to more modern platform newer cpu, ram, etc.?

Will changing to XFS already give me an improvement?

ReiserFS file systems, especially mature ones that have lots of use, are very slow, deletion can take ages. Moving files is worse than copying, because you have writes on both the source and destination, which are competing for writes to the parity drive.

 

It's quicker to use a copy function, then format the source drive after you are sure all the files have been copied successfully. This also has the advantage of being able to verify the copy is correct and complete before you delete the source.

In the meantime I upgraded one of my systems to a Topton n5105 NAS board with 16GB of RAM and parity check increased dramatically to 150 MB/s.

Have to do some more testing, but so far happy with the results.

 

Paid 133.-- USD for the boar and another 28.-- USD for the RAM.
