Summary: The Lexar Memory Stick Pro Duo for the PSP is great. I bought it for less than the Sony MS Pro Duo and is cheaper and better. When you reformat the Sony Pro Duo, you recieve 940 mbs, but with the Lexar one, you get 946mb. It's faster than the Sony one and I think everyone should buy it.

Summary: Purchased this little card for my new Sony T9 camera. At 6MP Resolution, it holds close to 300 pictures, which is amazing. It's perfect for long trips where you may not have access to a computer for downloading images. It even comes with an adapter, like the Sony ones do, so that you can use the card with older Sony devices that require the original Memory Stick. At 1gb, I think that this is a great investment!

Summary: I upgraded my digital camera & the one I bought uses a memory stick pro duo. I've been using Sandisk for quite a while & never had a problem with it. It uses the same, The speed is fast.
