Hi, I have Unraid which comes with KVM. I have an HBA with 8 SATA ports and the motherboard has 4 additional SATA ports.
At the moment I do not pass-through either the HBA nor the Motherboard SATA Controller.
I have a DS918+ with 2x 6TB WD Red and 2x 1TB 970 EVO SSDs and I am passing-through the entire drives to a virtual SATA controller(s). Recently I came to the possession of a X550 10Gbe and I realize that the SATA paravirtualization is rubbish. The write speeds especially for the SSDs are very slow 130/150 MB/s.
1) I was wondering if I pass-through the Motherboard SATA controller will I get better write speeds?
2) If the above is correct, when I build a new loader with the MB SATA Controller the DSM will ask me to reformat the drives or continue as it was? (I know always keep backup but in theory will it work?)
