What's the largest supported Memory stick size?

What's the largest size the PSP supports, I have the older model.

I believe the largest the PSP Memory stick is 16 gigabytes. I have one and it works great.Peabody99224

I was pretty sure it was 16gb, thx.

16gb for most people, but with a little work you can go 32gb.

16GB is the largest right now. 32GB will be here soon. 1TB in the future.
