My Ex4 connected directly to the PC via an ethernet cable (without router). Ex4 is not connected to internet.
During copy these files (299GB is jpeg& photo raw files). my writing to Ex4 is getting poor speed 15mb/ (raid10).
Have another same setting above, copy 970GB from HDD to Ex4 (raid 10) , it took about 18hours to completed.Write speed is about 15MB/s…This really slow ??? New FW getting more slower write speed ???
DavidSucesso test with firmware 1.02.42 , getting great performance close to the 80MB/s tranfster writing to NAS
