UnRaid speeds

[KTFirst]

Hi. I have a Epyc, 128GB RAM, Supermicro MB with 10Gbit LAN, running 10Gbit... and running Ironwolf PROs 18TBs disks (five in array, no cache), no other items or VMs (Krusader docker).

I am copying from a high end RAID5 NAS to the UnRaid server (using Krusader, mounted the RAID5 NAS into Unraid).

I get transfer speeds constantly of about 250Mbps... I understand Unraid is not raid. But this seems a slow to me.

 

Tips would really be appreciated.

Do you mean 250Mb/s or 250MB/s? If the former try turbo write, for the latter it's about the expected speed, Unraid can never be faster than single disk write speed when writing to the array.

Hi. The way I ”measure” is on dashboard it says inbound for the NIC. It states ”361.0 Mbps” for ex. So assumed it is bit.

Read up on that. Two things, can you enable turbo write for a while (e.g. during large transfers) then disable it? (obviously wo having to redo all stuff)...?

Yes.  You can flip back and forth as much as you want.
