May 16, 20206 yr Hi Guys First post here and i wish it could be more positive. Literally trawled these forums for days for help. I've been having extremly slow read and write speeds on my array since moving to unraid(Often below 1MBps). I've run a freenas server in the past but im completely lost as to what my problem is, Cant see what im missing. Im running a 2TB WD Red as parity as well as a identical drive and a 1TB WD black in the array, I also have an ocz SSD which i am using as cache. The server is hooked up directly to the router which supports 1000MB transfer speeds which a CAT6 cable. I've included my diagnostics in the post and below is an iperf test I've run over wifi. Can include a test done over ethernet but its honestly not much better. Literally any help would be appreciated!!
