Ok, so it's ample time I became serious and make my NAS dreams a reality. With a dead HD and a shaky PC, I think having a solid backup solution wouldn't be a bad idea.
But damn, those things aren't cheap. I'm not even sure I really need a NAS, I toyed with the idea of a re-purposed desktop PC, there is the cloud too... but at the end of the day the best would be to mix those options I think.
But still, those prices.
So I would use a NAS for essential file backups that are size insignificant like ebooks. Oh, and evidently the family pictures.
Then there are the old Music CD I would like to ripp, again not really big, even in lossless form.
Then I would like to ripp the 300+ DVD I have in my collection.
And the 50+ BR.
Is there other things I should totally do with a NAS ?
As for Raid, I think the secure one would be the one (forgot the name) that copy everything from one HD to the other, no ?
What should I aim for ? 2 bays seems really limiting, but 4 bays NAS are really expensive. What if I choose the 2 bays solution with big HD ?
Beyond backup I really would like to evolve my numeric life, as in have my data in one secure place and streams it wherever I want, be it Desktop, TV, Tablet etc.
Sorry if all this is your typical customer indecision, I really could use some help here.
