Here is my home network situation.
I have a router with a single usb 3.0 and several old sata I/II/III 2.5 inch hard drives. Is there any device that I can use to put, say, 4 hdd's in an array then connect the array to the router with usb cable? (I know how to mount a single usb device using dd wrt NAS feature via the router. Essentially I am going for a scheme that I can use some hardware for combining the hdd's.)
I also have a C.H.I.P. computer running as a server at home. Its power is pretty low so another possibility maybe to use external power for the hdd array then drive the hdd array using the C.H.I.P. computer. Again, I am not sure what the best hardware setup for that configuration is.
Any suggestion is greatly appreciated. Thanks.
