Ok, I have a sony digital camera and I'm looking into buying a larger card for it. Currently I can find a Memory stick pro duo card for about 10 bucks cheaper (for a 1 GB the difference is 48 and 38). My camera holds Memory stick pro, not duo, but the duo card comes with an adaptor that sizes it out to a non-duo card. http://www.newegg.com/Product/Product.asp?DEPA=0&Item=20-191-419&ATT=20-191-419&CMP=OTC-dealram Now the real question, would i see a performance difference using the adaptor? Because if I'm not going to, I see no need to pay the extra money for the non-duo card.
