Boot times can be pretty variable. Adding RAID controllers can significantly increase your boot time. For instance my controllers can take 30-45 seconds to load (3 of them, LSI 3208, Intel RSTe, and a Dell RAID controller) It's probably about 10 seconds after those till I get to the Windows screen. My RAID controllers take a while to initialize. Now if I didn't have that, my computer would start around that 8-10 seconds since I have RAID 0 Samsung SSDs that are pulling near 1 GB/second.
