SanDisk with first SDXC card
The extra video-recording speed. Panasonic, for example, will be issuing its first 64GB SDXC as a Class 10, 22-megabyte-per-second version card for almost US$600; however, SanDisk announced its first 64GB card at a slower Class 4, 15MBps for the more attractive price of US$349.99. True, only products announced since January–and only some of those–support the new SDXC standard, but even in a lot of the newer cameras and camcorders, Class 4 is sufficient for video recording. However, that 15MBps speed might slow you down when bursting in a midrange dSLR, which increasingly support SD media. Overall, I think going for the slower, cheaper memory is the right move for most people for now. Furthermore, if you just bought a brand-new, SDXC-supporting device, you can get that extra capacity today.
