Installed SSD in MBP and boot time is 45 seconds?

I have a month old 13 inch Macbook Pro (8GB RAM and 2.9 Ghz i7) and today
I swapped the stock HD for a Samsung 840 Pro. I've shut it down and booted
up several times with the SSD installed and it takes just about 45 seconds
each time. Is this normal?
It seems abnormally slow as I've heard MBP's with a SSD take between 10
and 25 seconds to boot up. It took about 45 seconds with the stock HD too.
Applications startup notably faster and it's not really a problem, but I'm
curious.
Any thoughts? Common problems that might cause this?
