I am not one to bash people but really what kind of question is this, especially for your first post?
A LOT of ipods out there and 2 seconds on google you can find this info.
What ever it says on the box... theres anywhere from 1gb to 160gb.
hi on the backcover of your ipod its says 4 6 8gb 16gb 32gb depending on what you got if you connect whit itunes you see that also and how many gigs are free
