Hello, ill make this short and sweet. Basically, I have 4x 500gb Western digital RE2 drives in a raid 0 in my HTPC for home storage. However, my dad thinks that it takes up too much power all the time and would rather not have it running 24/7. Im thinking that if I could get some kind of NAS and use the 4x 500gb drives than it would use less power? And then just get a small HDD for my HTPC and stream them to the HTPC? However, the 4 bay NAS devices I've looked at are all $400+. What do you guys suggest for a solution? Thanks!
