After getting BURNED badly with a Kingston 512MB Secure Digital card, I went on a search for a new one. I ened up getting a Transcend 45x 512MB Secure Digital card from NewEgg.com for $99 shipped. It simply SMOKES my Kingston card and the 512MB Panasonic card that I had before it (had corruption issues). I ran the same tests as Jason on my Transcend 512MB card with my internal 6-in-1 USB 2.0 reader on my desktop machine (connected with the internal USB 2.0 headers on my motherboard).
