Hi,

 

I have an i5 CPU with 32GB ram, 1G network card, cat6 cables, and I have ran openspeedtest docker ...the speed is super fast. but when I actually copy files from my unraid SMB to win 10, the write/read speed is around 30MB/s.  and to mac is around 50MB/s.

 

Any ideas why it is so slow? 

I have followed this , but still not working

 

Attached is the diag log. 

 

Thanks so much!

A parity check is probably in progress which is going to degrade your RW performance.

Make sure that your plugins are up to date.

@Squid Thanks! that was an unmouted network SMB share. I have removed it. and now the log is clear. but the speed still the same...

Is it the case ?

I have no parity disk. just 1 hard drive.

You first disk is an SSD and it seems a really cheap model. I think you need to install the TRIM plugin.

OK.  Looking closer now thanks to ^^^

 

Perfectly valid configuration of what you've done, but you will get better performance by assigning any cheapo flash drive you've got kicking around as disk 1 as the nvme as a cache pool.  (And just ignore that disk 1 exists)

 

Array devices do not support trim at all.
