How do they do it? If you've been following along, you already know: with an 8GB SDHC memory card.
A word from a memory maker
The majority of the camcorders that drew the most attention at CES were able to shrink because of the use of flash memory, either built in or taking the form of removable SD media. But not just any SD media.
For most of these high-def camcorders to work properly, they must use SDHC cards, which operate more quickly than a standard SD memory card does. SanDisk, a leading SD Card seller, recommends SDHC, which can handle data transfers of up to 40 mbps. The 4GB version retails for US$80, while the 8GB version retails for US$140.
