Sony vs Sandisk memory stick pro duo

[Ruriko]

Which brand is fastest and reliable? sony or sandisk It is for Sony DSC-W150. Currently sandisk seems cheaper than sony but I dunno if it's good. Is there a difference between duo and pro duo?

Both are reliable. The specs will tell you which is faster. For memory cards, buy what you need and ignore the brand names; there's very little difference.
