1) There are actually two types of Secure Digital (SD) cards: SD and SDHC. SD cards cary in size and go up as high as 1gb only, SDHC the HC stands for High Capacity starts at 2gb and goes on from there.
According to Newegg
and others, the SD cards went up to 2gb. I have an older reader that is SD only, and 2gb SD cards are the upper limit of what I can read.
