dd's default block size is not aligned with block sizes on the flash eeprom, so you do a lot of unnecessary rewriting. Increase bs= from the default 512 bytes and it should be faster. Current generations of Flash storage devices are not too good at sustained sequential access like dd will give, especially for writes. Flash is useful in some situations but has strengths and weaknesses.
