Looking for some feedback to this dilemma. Hope to get some feedback from people who actually went through this process. Trying to do this correctly since it involves money and probably lots of time. The dilemma is, which is a better setup: setting up a NAS or Windows Home Server (Vail)? Here are my goals: Be able to stream ISOs (want to preserve highest quality) for my movies, share photos and music thought out the house, back-up many PCs in my house. I have a home office which I can keep either the NAS or WHS in. All of my PCs are hard wired to a switch. Only one PC in my house will do most (90%) of the movie streaming. This PC that will do most of the streaming is a Windows 7 setup just for HTPC. PC running AMD Phenom 2, Nvidia GT430 GPU, with 4GB RAM plenty of horsepower to handle anything I wish to throw at it. Thinking about running XBMC has my media center software. The good thing with WHS is, there are plenty of software that can run on this server…example would be My Movies and TVersity. Not sure what software can run on a NAS besides the software that is bundled with it. Bundled software are okay, but 3rd party software tends to give you more freedom with various plugins. Planning on mounting the ISOs on the NAS or WHS with Virtual Clone Drive software from AnyDVD. I have been reading on this forum and other forum, people have been expierecning some shutter issues while playing their blu-ray ISO movies. Some of the users have pin pointed that their NAS is not fast enough to handle blu-ray streaming. From reading the many NAS specs, all NAS are equal in spec. Maybe once these units are tested in real word scenario, things are a bit different. Some users suggested to get a switch with QoS to be able to better handle the traffic demands. I have kids, so while I am streaming I am sure they are surfing the web on the same network. Just looking for any thoughts….
