Sure we've seen 4GB and 8GB Class 6 SDHC cards before -- Lexar's got a pair, as does Transcend -- but when it's SanDisk that steps up to the plate with new Ultra II and Extreme III models, well, that's certainly worth a mention. As we're all well aware by now, Class 6 cards have a minimum sustained write speed of 6MBps, though both the 8GB Ultra II and 4GB Extreme III easily surpass that, clocking in at 9MBps and 20MBps, respectively. Available in June -- along with the new 4GB EIII Memory Stick PRO Duo card -- the 4GB EIII will retail for $180, the 8GB UII will fetch $240, and both models will toss in a "free" MicroMate USB 2.0 reader.
