Who writes about the low speed of copying - most likely you run into the speed of the router. I had a 100 megabit - the speed was 10Mb / s, I replaced it with a normal gigabit, the speed is a little more than 100Mb / s. Has some pros: All the pluses have already been described in other comments - this is functionality, speed, not loud operation (you can hear the cooler if you put nas nearby, if you put it away from the computer, you can't hear it). With its cons: No obvious ones yet. Interface from the beginning of the 2022s, for an amateur. But it doesn't affect functionality.
