uggg.... I need to find something other than FlexRAID as well. I thought I would buy it, but I have been trying it for a week and it has not performed well at all. It frequently hangs on validate and verify commands. The RAM (8 GB) fills up and it just sits there. When I try to shutdown or reboot, Windows says it is performing operations and it hangs. I have managed to do one restore command successfully. I will try to simulate a HD failure by spontaneously disconnecting a drive. After that I do a refresh, and FlexRAID still shows all my drives as healthy, even though one is physically disconnected... I then access my pooled drive and it hangs as usual. I reboot, and try to validate - it hangs. I have only had the trial a week, but now it wont let me continue trying it. It wants a registration key even though I have a week left on my trial.
It really sucks that there isnt really a better solution to get a backup parity drive on windows. I dont want to build yet another computer just for unRAID, but I suppose that is the only option I have...
