Hi,
I am setting up my nas for the first time. I am using 3x500gb internal hard drive and 2x500gb external hard drive (connected via usb) however these drives are not showing up when I try to put them into RAID, I believe this is because the devices are connected via usb however I do not know what to do as I would like to have the extra 1 TB of space. Please let me know if I need a plugin or what I can do. As you can see from the images the drives are showing up but are not actually allowing me to put them in RAID
Thank you
