So, I have swapped out the old 60gb on My ps3 and introduce a 120Gb from my old xbox360 (properly formatted)

I updated the Ofw (not jailbreak) and have been transferring movies from my desktop to my PS3 via tversity. Now I come to realize my harddrive is at MAX capacity and I require to upgrade again to a bigger size hard drive.

Before I go get any pSata harddrive I want to know what is the max size *GB* harddrive I can put in an Ofw PS3.
