SD speeds at about 50,000 I expect on the clock port, can you tell me exactly how you managed to achieve 11,000,000 though on the sdhc? I'm not calling you out to be a lair I just don't understand how you've achieved that performance and for me it makes me think an error somewhere?, for us on the a1200 expansion board we're lookin at 187,000 at 14mhz on any SD card right now, so perhaps there are options to explore to improve performance here ourselves say 25mhz SPI. Perhaps you can tell me the details of the SD card itself make/class etc and the spi clock. any particular CMD's you're using and block size. We'd all like to hear it? Thanks mate.
Edit or sysinfo is being silly, let's find a reliable speed test tool and stick to it ? hmm
