Are there fake SD cards?

How do SD cards store so much data?
SD cards are build with memory chips. Memory chips store data using electrons. The number of electrons used to store data are ridiculously small. There is this tiny bucket called a bit-cell that can hold electrons from escaping.

How many photos will 1tb hold?
2 million photos“Assuming that the average size photo is 500K, then a 1TB HD will hold around 2 million photos. The arithmetic is easy: 1TB = 1000 GB = 1000000 MB = 1000000000 kilobytes. Divide 500 kilobytes into that for 2000000.” So, the answer is 2,000,000 (2 million) photos.
