hi
what are the main advances and differences between these 2 devices?
i'm asking cause i've bought 4x10tb hdd's and to get the data from the old 6tb drives in a 5104 to the new ones safely, i've bought a cheap 6104 to "just" copy the data.
when this'll be finished i have to sold one, but i'm not sure which of them.
the display thing and 4k doesn't matter....
thx alot!
