Look no further than the new SanDisk Extreme III SDHC cards that comply with the new class 10 specifications…
…and offer speeds of 30Mbs for both reading and writing.
Recording 1920×1080 AVCHD video on a 32GB card will yield you 160 minutes of video, or you can store 2500 RAW format imgaes. Expect to see the 32GB version of the card in August for an unknown sum of moola.
If you can’t wait, you can always pick up the 16GB version (SDSDX3-016G-A31) for about $93 here.
