Any thoughts on those 2? I know the 1512+ has 5 bays and is leagues faster plus has the ability to expand to a 15 bay device (real nice) but the price is around $800 compared to the $400 for the 413J which is only 4 bays, no expandability and a lot slower.
Main things I will be using it for would be to store my dvd/bluray collection and distribute it through the house and maybe pictures. I was thinking of using PLEX to be able to watch things on my tablet but I do not count that as a needed thing if that is the only thing I would have to spend the extra $400 for.
I love the 1512+ but, to be honest, the price is the sticking point. $800 for a NAS and then another $700 for the 5 drives is freaking expensive lol If I go with the low end 413J I would be under $1000 with only 4 drives but would I be happy with the performance?
I hope to get some answers REAL fast because the egg sale ends tonight or tomorrow and I want to get the stuff ordered ASAP so I dont miss the sale. I would just order 5 of the drives but the 413J only has 4 slots

Really hoping some people on here have used both and can give some real world advise. I love looking at speed charts but it just isnt the same as first hand knowledge.
