I tested SD file read/write with an UNO R3 and microSD. I want Final product to be this 3.3v mini and a standard SD card. The UNO is 5V/16Mhz and this is 3.3V/8MHz. Will the read/write times to the SD card be significantly slower at 8Mhz? (Is this the obvious answer: "The 8Mhz board will take twice as long as the 16Mhz to write to the SD card.")?
