Question: 1tb holds how many pictures?
Answer: “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.
