Then bought another (back it up
180-200M/sec throughput is the norm. On the network. Beats out most external drives I've ever come across. Everything ties into / backs up to the array. Home and work now too.
I use everything but Microsoft products. They're shit.
My filesystem is 60T w/ under 10T used today. I'll consider plugging in more drives or changing them out in the Synology somewhere between 2017 and 2020...
