Dear Unraid Community, 

 

I have HP ML110 Gen 7 - E3 1220 - 4GB RAM, I'll be upgrading the CPU/RAM to 1280/16 RAM. ( parts requested, awaiting arrival ). 

 

but until then i have connected my HDDs as following

( i know i'm using green HDDs, but all of these HDDs are brand new ) 

parity sync takes too long (2 days, 8 hours) with speed of 20 Mbps . which is very slow. I have attached the diagnostics. can you please help me diagnose what is the issue and how can i fix it ?

Nothing obvious in the logs, check to see if there's a write cache option in the BIOS, if yes set it to enabled, you can also run a test with the diskspeed docker to confirm disks are performing OK.

Thanks A lot @JorgeB , 

 

I have changed the following settings: 

 

SATA ( from Legacy to AHCI ) 

Write Cache - Enable ( before it was disabled ) 

 

now getting 150 Mb/s
