Memory Recommendations

I bought a launch 60GB PS3 and for the last year my memory peaked. I've been sacrificing games to save memory. After New Vegas I'm running low again. Any recommendations about what to get? Do they have memory cards for the PS3? I prefer any external device over opening the PS3.

Don't really need to open the PS3 to replace the harddrive, theres a slot at the side of it where it fits in. Just have to remove the plastic thing and unscrew the blue screw with the correct screw driver. Which is incredibly easy and takes about 2 minutes. You can back up all your saves on a USB memory stick.

Oh.. Sounds good then, I thought I had to go Frankenstein on it. Thanks.

Yeah forgot you have to remove the screws from the harddrive metal case when you take it out.. Also easy.. Just follow this guide.
