Rig Details:
I have setup a new TrueNAS box so a bit of a TrueNAS NEWB. I am having an interesting issue with data transfer.
If I move data onto my SATA RAID (4x 10TB HDD's) I am getting max throughput for my 1GB LAN and at this time happy with this (Going to look into LAGG later if compatible with my CISCO Switch).However when I do the same onto the SAS RAID I start well at full throughput again but at about 45-50% the speed drops to anywhere from several kb to 30-40mb. I have the shell etc open on a monitor next to me and there are no errors shown. I have tried this with and without the NVME SSD as Cache and it makes no difference.
I am confused as its on the same controllers as the other pool and I am under the belief that SAS is better than SATA (At least that's how its always been in business for me). So I am sure we can rule out LAN and HBA's based on this. Does anyone have any suggestions or things I could try?
Thanks in advance.
