[Solved] Extremly low disk speed

Featured Replies

Hi All,

I am a new unRaid user. So I am sorry for any noob questions.

 

I started the unRaid server couple days ago. I have an arrey of 6 x 4TB HDDs. 4 WD Red + 2 Seagate IronWolf. For some unknown reason to me it tells me that the parity sync will take 30 days. My disk speed is 937 KB/sec (!?), is this normal?

 

Total size:     4 TB

Elapsed time:    56 minutes

Current position:    1.28 TB (31.9 %)

Estimated speed:    936.8 KB/sec

Estimated finish:   31 days, 3 hours, 28 minutes

 

TIA

There's something reading and writing to disk3.

Yes, I am trying to copy files from an external drive (backup) It writes at speed of 5 MB/s. Also extremely slow. 

During the parity sync avoid other array activity, or both operations will slow down a lot.

Thank you!!!

 

I stopped everything else and now I am down to 10 h for sync. I can live with that.

 

Thanks again :)
