Win 10 & Blackmagic Decklink Quad2

10.8.3 works now with my quad2 and Trilevel 1080i50 sync
output is sometimes laggy when playing another file on the same or another channel.
maybee i need to put another ssd and form a raid 0 for my medias
should i use the motherboard raid controller or would you strongly advice to use a raid controller card?
