I'm looking for a sd card for a camera i'm getting for Christmas. I saw a kingmax 60x which is a 10mb/sec max tranfer rate card for $35 (256mb) but i also saw a sansdisk ultra II which claims it handles no less than 9mb/sec write for $45. is this just a marking ploy is the sansdisk going to write faster than 9mb/sec at times and the 60x card is it going to write slower then 10mb/sec at times? anybody have any knowlege on this?
