Hi JorgeB,
I really don't know what the problem is with the transfer speed between my desktop pc and my NAS device but i runned the parity check again and changed Tunable (md_write_method) into reconstruct writes afterwards but it's still maximum 50mb/s. Why is this so slow?
I don't have the option to use a cache disk so i am just running 8 Seagate Barracuda 4TB disks and two of them are parity.
