first SDXC-card 512GB comes
SanDisk supplies as the first manufacturer SDXC cards with 512GB.
Now we are already only 2 steps from the SDXC specification limit of max. 2TB away, which was published in 2009.
The price of 799 USD, of course, is also enormous.
high-speed SPI mode of the SD/SDHC/SDXC-cards supported
The MMC/SD-port now supports for all SD-cards the high-speed mode too (since SD 2.00 specified) with max 50MHz. But this is optional for the card and is not supported by all manufacturers (such as SanDisk 03-4453) offered. If it is possible, now reverted to high-speed.
