All, I am looking to add a NAS to my home network. I am running a late 2013 iMac with El Capitan. Connected to this there is a Time Capsule, an airport express to extend the wifi and a 3rd gen Apple TV these are all connected via a small CAT5 network. I would like to add a NAS that I can use as a media server and possible personal cloud to store both media, mainly iTunes associated and photos including GoPro footage as this is burning through my HDD quickly. I have looked at the QNAP TS-212P as a budget starting point but have heard it's difficult to install I am a novice to networking so please bear with me but all guidance gladly received.
