So one of the reasons why I wanted to go with windows is because I have 2 small HDD's (350 GB and a 500GB) which will be enough for the amount of movies and shows that I plan to download anyways. Therefore I've heard that using freeNAS means you cannot upgrade later on (dunno if that's true or not just remember hearing it somewhere) so would having windows be more convenient if I do decide or need more storage to upgrades later on. Ok did some research and wanted to ask if its worth doing RAID 1 on a 350 GB and 500GB HDD and how much storage would I end up with?
