I don't know exactly what is causing this yet but when I wake my 2012 mini from sleep it takes a few seconds before it will "come alive" so to speak. I have an internal Samsung Evo 250GB ssd as a boot drive and a CalDigit T3 external in SW RAID0 for my home folder and iTunes library. I suspect that the delay may be due to the SW RAID accessing the T3 but don't know for sure. The main issue is that my AppleTV is timing out when trying to connect to the library if the mini is asleep. Any ideas? EDIT: I plan to do these tests but can't do them until I get home tonight: 1) Move home folder back to ssd. This will test if having the home folder external is the issue. 2) In addition to above shut down iTunes to see if iTunes access to a SW raid volume is the issue. 3) in addition eject the T3 and shut it off. This will tell me if mounting and loading the SW raid drivers is the issue. I suspect that the real issue is #3 which will mean that I need to use hw raid for my external. This is my first experience with SW raid.
