When it comes to claims of being the world's first or fastest, there's a big difference between announcing product and actually delivering it for retail. So let's be clear, SanDisk might be announcing the world's fastest 32GB SDHC card today, but it won't be shipping until August. It's not even the first 32GB class 10 SDHC card announced since Panasonic did its unveiling
more than a month ago -- and this is where SanDisk's speed claims get confusing. That "class 10" logo is supposed to be a standard means of identify the card's speed as rated by the SD Association. Yet SanDisk claims a max read/write speed of 30MBps whereas Panasonic claims a max of just 22MBps. Guess we'll have to see head-to-head benchmarks to know the truth. Regardless, it is fast and that makes it suitable for capturing 160 minutes of full HD (1920x1080 pixels) video recorded at 24Mbps.
