The iTunes Store has about 37,000,000 songs available worldwide.Lets immagine each song is encoded at the highest mainstream MP3 Quality (320 kbps), and that the average song is 4 minutes long.320 * 4 * 60= 7.7 Megabytes per song7.7 * 37,000,000= 285,000,000 Megabytes =285 TerabytesA modern archive HDD can store 8TB worth of data so 285/8 =36.6 Hard Drives.But it gets better…Modern Micro SD Cards can store about 200GB of data per card. Each Micro SD Card has a volume of 165 mm3, and a mass of 0.5g.We could store the entire iTunes Library on just 1425 Micro SD Cards. (285/0.2 = 1425)The cards would weigh just 713 grams. They would take up the space of 235cm3 meaning that you can fit the entire iTunes Library in an empty can of Coke.
