Unraid Read / Write Speeds very inconsistant

[chris1204]

My Unraid Read / Write Speeds are all over the place from 1 MB/s up to 50MB/s

I have 2 8TB HDDs and 2 3TB HDDs and 1 Cache SSD 500GB.

As soon as my Cache SSD is full the Copy Speed is very slow between nothing and some MBs.

I Tried Turbo Writ wich didnt Help.

Diagnostics File is uploaded

I Dont know what to do about it

Parity and disk1 are SMR, so that kind of fluctuating write speeds are consistent with that, read speeds should be constant, if nothing else is writing to the array.

How are you currently transfering your files? Over the local network? If so, which protocol are you using (SMB/NFS)?

Some info on SMR drives and Unraid.  SMR drives for parity are usually a very bad idea.
