We knew it was only a matter of time before we had 16GB of SDHC goodness staring us down across the internets, just daring us to make the first move, but we just didn't know it would be so soon -- and so expensive. Apparently MICRODIA is prepping a range of SDHC memory to be launched in Japan this month, including a pair of what sound to be the world's first 16GB cards. They're all aimed pretty squarely at performance, with 4 and 8GB Class 4 52x cards; 4, 8 and 16GB Class 4 82x cards; and 4, 8 and 16GB Class 6 160x cards. The latter will cost you dearly, with the Class 6 16GB SDHC pictured above selling for a whoppin' $3,500. When you put it that way, our collection of 4GB SDHC is treating us just fine, thankyouverymuch.
