I am struggling to get transfer speeds of over 100mb/s between my SSD and NVME. Today I transfered some files from one drive to the other via unbalance and averaged 87MB/s this seems really low and I feel that I have a setup issue which is causing this but I do not know what. I feel like this should be 5x faster, I have the SSD in a 2 disk array with no parity or cache drives. any advice would be appreciated.
