Hello, I appreciate the help.
My unraid server was running fine with 3 drives (still does when I remove 2), but when I added a fourth it went all down hill. When parity check or read check is run the speed goes from 230 mbps to 200 kbps on 18tb drives (finishes in 1000 days or more). I've changed mobos, cables, connected directly the drives to the ports jumping the chassis completly, changed cables etc... I also changed 2 drives in the array, but with four or more drives, it wont work right.
currently the system is set up in an Asus n100 mobo with a PCIEx1 8 port sata card, previously it was set up in a Chiwi n6005 mobo with onboard 6 port sata.
Again, thank you for the help
