__NOWYSIWYG__ Here are some benchmark results for various SD card brands which were acquired with the new benchmark option of the CHDK. Maybe also see BenchmarkVideo60Sec. The higher is the value, the higher is the speed [kb/s], the faster is the memory card. Take them with a grain of salt: The first benchmark round sometimes shows too low numbers and there are some unknown variables (Which firmware version of the cam was used? How full/fragmented was the card? FAT16 or FAT32? Was the card original or fake?)
