LinuxQuestions.org - SSD -> How to check alligment?

Got a brand new ssd -> SSDNow S100 16gig -> http://www.kingston.com/ssd/S100.asp?id=8
Done a brand new fedora 16 install, I guessing ssd should have been alligned automatically by anaconda by How can I check if its alligned?

Code:

GPT fdisk (gdisk) version 0.8.1



Type device filename, or press <Enter> to exit: /dev/sda

Partition table scan:

  MBR: protective

  BSD: not present

  APM: not present

  GPT: present



Found valid GPT with protective MBR; using GPT.

I'm not sure but from what I read this GPT means its alligned correctly? How can I check alligment from fdisk? I'm just interesting in understanding the calculations, which my of diy guides does not explain well
