After downloading a shit load of stuff from psn and getting playtv, I no longer have any space left on my 80gb HD so I need to upgrade. What drives would people recommend and what's the best way to exchange it?

How much would I need to spend on this? I have a budget of £50 (give or take).

Try using an external hdd

So it is THAT simple, right?

Just plug in the external hdd and off you go?

I can use the external for all my playtv stuff but the game related stuff is still the issue, I use my 160gb external HD for backing up the ps3 and the odd video stuff but it's getting to the point where the games outweigh the videos. I have a backlog of demos to download and try (put it this way, I started downloading darksiders 2weeks ago, I've yet to finish downloading it) but I'm not around as often anymore since I started my new job, so I need more memory for them to sit and wait.

I recommend you start deleting games. And you get a faster internet connection.

Check this link. Only 43.00 on Amazon.co.uk for 320gig

^^^^^^^^^^^

This.

cool, thanks. I'll short list it, I suppose I could just delete all the things I no longer play or watch anymore but I hate having to do a delete every few days and so on.

Get a 320 and noted - having lots of space on PS3 is great and with PlayTV I think ungrading the HDD is a must.

thank god for HDDs on consoles... (then again XBL PSN and WW are good additions to console gaming).
