Hi guys,

Picking up a PSP soon and wanted to know what is the best card to go for. Was thinking of the 8GB version.

Was thinking of the SanDisk 8GB Memory Stick Pro Duo. Is the following faster:

Sony 8GB Pro Duo Memory Stick (Mark 2)?

OK guys, I've come down to two cards:

Sony 8GB Mark 2
San Disk 8GB

What to go for?
