How fast should an SSD boot time be?

thanks everybody that replied. So it seems to me so far, that 30 seconds from start button to desktop is typical for an SSD.
I also used msconfig to disable a few start-up programs (I doubt that this is going to help much because an SSD can load programs in matter of seconds, I think, but correct me if I'm wrong) I also disabled GUI boot. I can't seem to disable the BIOS splash screen from the BIOS menu, as ADDRam suggested. I'm down to ~25 seconds. I don't know what more I can do. I'll look at those links some of you posted. But man, I was really hoping there was a magic way to achieve a 10-15 second boot time.
So it seems to me now the only way to SIGNIFICANTLY reduce my boot time is to upgrade to either windows 8.1 or 10 because those OSs have fast boot and hybrid shutdown, which can really reduce the boot time compared to a full shutdown and full start-up. Is this accurate? (i will certainly upgrade to windows 10 later on, but now - and I'm satisfied with windows 7, and the ONLY reason I would have upgraded to windows 8.1 is for that really fast boot time, which I should also get with windows 10, correct?),

No not really 7 on a ssd is just as fast as 8 or 10
10 you have a lock screen you must pass
Disable that and 10 goes into a coma.

Can't remember if 8 has a lock screen or not :/

Yes, but I am referring to just the boot time alone. Don't Windows 8.1 and 10 both boot faster than Windows 7 because of a feature called Fast Start-Up and Hybrid Shutdown??

Because I've read that Windows 10 combines the best of Windows 7 and 8.1. I like my windows 7 just fine right now, and since most people still prefer windows 7 over 8.1, I would assume the same for others. However, the main thing, perhaps the only thing, that I like about windows 8.1 over Windows 7 is Win 8.1's fast boot time. This causes windows to load even faster during boot. Doesn't this same fast start-up feature also come with windows 10?? This would actually be my main reason for upgrading to Windows 10. I am more interested in a fast boot time in Win. 10, over its other features like Edge browser, Cortana, etc.

Fast boot is a feature of UEFI BIOS and sometimes cause issues with devices not loading.

Boot time depends, a lot, on the amount of peripherals that are plugged to the PCIe slots of the motherboard and to the PC's USB slots. When you have a few PCIe cards (graphics, USB3 hub, sound) and a few USB permanently plugged (wireless emitter for the mouse, UPS control, Joystick, Switched USB2 hub, Keyboard, Monitor's USB3 hub, Front-case card reader, Printer, Scanner, Quadrant for flight simulator, Gamepad G13 and Pedals for flight simulator, your boot time can be as high as 2 minutes with HHD, reduced to less than one with SSD.
