I am trying to decide on my home network setup and running into some issues and questions. My current setup is a full boat rMBP 2013 with a LG 34UM95 monitor. I have a 2TB USB2.0 drive connected to the display which I use to hold various files I don't access all that often. I have a 4 bay USB2.0 drobo that is pretty much maxed out connected to the monitor. It is partitioned to contain my time machine backup and my iTunes library. It is fast enough for the iTunes. I have an old airport that I am considering upgrading to a 3TB time Capsule. I have an old iMac on my network that connects occasionally to the network (kids computer). Will its presence throttle the network solely when it is up and running or as long as it is on (sleep or awake)? I am considering two options. Either the 2TB time capsule and use it for time machine and get a 2 TB thunderbolt drive to connect to the monitor or a 3TB time capsule that will be partitioned for backup and my video files that are growing and growing. Can I edit video across a network using 802.11ax or will it get throttled?
