So - I'm getting a NAS - this will be my first NAS device. I had planned on getting a QNAP TS451+ as there is a decent deal out there if you know where to look. Problem is though that originally I had planned to put two 4tb Reds in it, with a view to adding capacity down the road. However, I managed to snag a couple of 6TB Reds at a decent price, so I'm now wondering if the 4 Bay idea is still sound as it'll take me ages to fill 6TB - (I plan on using the NAS primarily as storage for family photos and video) so it needs to be able to serve files on my home network, but also for my parents to access remotely. I'm sure it'll also hold the odd movie and audio file on there too. Question is, should I be looking at getting the 451+ or get a 2 Bay like the Synology 218+ which I can get for a little less than the TS451+. Which device gives you best value? PS - I may end up using Plex as well, though not 100% sure at this stage. Any advice will be really appreciated.
