PS3 HDD question

I just bought a 40gb one week ago and only have 3 games oblivion rainbow 6 vegas and mgs4 but it says I only have 21gb of free space left out of 37gb is this normal?

p.s. I have not signed up for playstation network or downloaded anything yet.

you know what i forgot to tell you. I think that the reason you are struggling for space is because the system itself has to have information for the ps3 to run. I worded that badly but for example it takes space for your backgrounds, settings, os etc.fizzlegloop

exactly. plus with game installs, space gets taken up pretty fast. that's why many people get new hdd's.

I have a 20 gig but I found someone that will buy it. I'm planning to get a rare 60 gig (I know a friend that doesn't really play his PS3 and willing to sell it to me) or I'll buy an 80 gig if it's bundled with a DS3 or even maybe just wait till the holidays and see if there's any new PS3 bundles, most likely.

But yeah, I think that's normal with all those installs and such. I rarely download trailers and demos over the PSN if I can play the demo over Xbox Live and see the videos over the internet. Plus I buy more blu ray dvds than PS3 games. I've bought Uncharted and Ratchet, and I traded those in for MGS4.
