If only that were true.
... take a look at this link to understand SPI and SD cards.
You may have noticed the large number of people who are having trouble writing their image(s) to the SD card and getting the pine board to boot. This is NOT due to bad hardware , and is usually not due to bad software, but is almost always due to the fact that SD cards are easily corrupted and sometimes permanently damaged because of improper shutdown and improper software access in other devices (as well corrupted--- as in permanently damaged cells in the flash area of the card.
The reason reformatting does not work to correct the card is that the image write process (dd and win32diskimager) do not follow the 'formatting' , rather they write the disk image ( tree, meta-data, and data) out to the card bit-for-bit. If the SD card is not compatible with the binary image, if it has holes in the flash, if its structure is damaged from improper access or shutdown, that write will never work again and the card is not worth the plastic its encased in.
This is the reason I only use NEW cards; Samsung evo plus Class 10 32Gb cards are the best bet...
... always shutdown properly, and never just yank an SD card ! YMMV
