Upgrading my PS3 harddrive; Advice Requested

[Ghadente]

I am strongly considering buying a 320GB HARD DRIVE FOR Sony PlayStation PS3 2.5" 5400 RPM because i have already reached a point where i need to start deleting some things on my current drive to make room for new games and downloaded content.
I wanted to post about it so i can get some feedback on this from others who know better.

i'm buying it on ebay for only like $60 total. here are the specs:
Capacity (GB) 320 Form Factor 2.5" Notebook
Rotational Speed (rpm) 5400 Seek time (ms) 10 Average (typical)
Buffer Size 8 MB/16MB Drive Type SATA
Weight 98 (g) Buffer to/from Host Max 125MB/sec
Dimensions (mm) 9.5(H)x70(W)x100(D) Product Life 5 years or 20,000 power ON hours

I have heard 7200rpm will cause more heat for only a little faster speed so i've decided to go with 5400 since i have had no concerns with loading times.

I want to make sure there isn't anything i am missing, or if there are any other considerations that should be taken into account before i "commit to buy".
should i go for the 500gb or is 320gb enough?
Also, I am worried about transferring data from my current to new hard drive. what's the best way to go about that?

I personaly got a 250Gb HDD for my ps3 and still works a treat. So if you're happy with what you listed above thats fine.

My only advice is that before you swap them over, save your games saves on to a USB memorystick if you don't have the equipment to do a full backup. You can always re-download and re-install game data like add-ons and stuff without buying them again buy going into the PS store and 'view downloads'.

If you don't back-up your saves you may not be able to get them back like what happend to me. I lost a years worth of every thing i played.

You'll be fine as long as You are going for a 5400rpm. The PS3 has a dislike for 7200rpm models. For unknown reasons.
