Upgrade HDD help

Hello,

I installed CFW a while ago, and it was surprisingly easy to set up, thanks to the Reddit community for guiding me through it.

Now, I’ve been playing various games I missed out on back in the day, and I’m finally getting to enjoy them. 😄

My PS3 is running the latest CEX version, which has something to do with developer features. I’d like to know how I can upgrade from an old HDD to a new one. Is there any chance to use an external HDD instead? Lastly, what is the maximum storage capacity the PS3 can handle?

Many thanks!
