there is several reasons for the differences.
-SSD disk will make a lot of difference. If you get two in RAID0 then startup may be faster. mSSD is slower than SSD. 125GB is slower than 256GB but 512GB is not faster than 256GB. Fastest are Samsung Pro series. I would not buy SSD only to get faster boot time.
3) services running
4) registry tweaks (turning on serialization will shorten startup time a lot)
5) disabling visual effects will help too
