I went to buy a flash card for my D70 and the salesperson suggested I get the Hitachi 4GB Microdrive card. I ended up buying it but am not sure which type of card is better, the microdrive, or the compactflash card? Also, do you think it is a mistake to have so many pictures on one card? I intend to downloac them to DVD's as quickly as possible after I have taken them. If my questions are too basic for this site, I so apologize. It is just hard to resist taking advantage of all the expertise that is floating around here. Thanks.
