Faster disks or controller, depends on where the bottleneck is. Typically it's the disks.

I used the DiskSpeed docker to check all disks they are all fast enough.

I think there is something else solowing down the whole maschin...

Parity disk is SMR (also disk6), but parity can really have an impact on all write performance.

i do not think it should be so slow.. 

Those are read speeds, SMR is slow for writes.

but not 10 MB/s slow

its still goin slow as hell.. is there a way to swap the slow wd drive with a faster one from the array? i can move all the data from one of the drives and use this one as parity.

Very possible to get 10MB/s writes with SMAR drives, I get that with some of mine when they hit the SMR wall, you should at least avoid SMR for parity since that will impact writes to any array device, even non SMR.

i have now swaped the SMR drive i will check and if its still slow as hell i will post again ^^

Its still slow as hell???

I down't know what to do.. is it normal for unraid du be so slow?
