Tired setting up an NAS 10 years ago with QNAP TS-209. Still have it, basically new with minimal use. Could never get it to work and boxed it up out of frustration. Was definitely not just plug and play. 10 years later, new Windows 10 based network, with typical hope peripherals including a PS3. I want to be able to share files with others in the house, serve media to my home entertainment center, and log in remotely to access files when away. Most of all I want it to be painless to set up and reliable.
If you want something easy to use then Synology will do a better job. The public folder will be visible across the network, so you can connect from computers or TVs and stream or store the data. Simple DS218 would offer a drive mirroring and fast enough interface to do the job.
I hope this helps.
