Yea, I'm definitely going to take Windows up on this. Different size drives, parity, can remove/replace, support for larger size drives, and there is no max amount of drives you can use. I'm not against unraid at all, but if Windows 8 actually comes out before unraid support 3TB drives on a stable platform then it is a no choice situation. And I'm sure the write speeds will be on par with an optimized RAID, which is a huge plus. Trust me, the last thing I want to do is worry about another entire OS running, having to keep updating it, maint, security and all that. Not something I would like. But imagine installing Crashplan easily on it and selecting drive F: which is a 20TB pool and looks like one big drive to anyone using the system. Hahahhah. Sounds good to me.
