Wanting to start a NAS for multimedia at home

[Enquiries]

Been using multiple portable drives for years now. As movies are growing larger in size and the drives growing older, performance is starting to slow. I've been out of the loop for a couple years so need something fairly simple to help get me set while I learn things. Been looking at the DS224+, but just want to know if that's the right thing for me, or if you may have a better suggestion.
