not 100% sure what ya mean there lolbut a raid card will add to the preboor times yes. As it has a bios and drivers to load just as your onboard raid does. Now will it be longer than the onboard?? I cant say for sure all depends on whats needed to be loaded. If it was my rig I'd just run on the onboard and be done with it. I do it with my 2 Hyper X 3K's in raid 0I know you yes early but will i good raid card low the boot time ?
