Editing 691: MicroSD

Randall's claims in the title text do check out. A high-density floppy disk with a FAT format holds about 1.4 MB of data, and has dimensions of 90×94×3 mm, for a volume of about 25 cm³. A refrigerator carton is the large cardboard box that fridges are delivered in. A typical refrigerator carton may be 1800×700×700 mm, a volume of about 0.9 m³. So a fridge carton could hold about thirty-five thousand 90 mm floppies, or roughly 50GB. This is comparable to the storage on a single microSD card. A soda can (500 ml = 500 cm³) could hold three thousand microSD cards or store 50TB of data (4500TB today). The iTunes store claimed to hold thirty-five million songs in Summer 2016, and allowing for about 2MB per song gives 70 TB of music. But the library would have been smaller in Spring of 2014 when the comic was created. As of January 2023, Apple Music had about 100 million songs, with much larger average file sizes of around 6 MB. That amounts to about 600 TB total, which is still far less than the 3000 TB that could fit in a soda can of microSD cards at the time. So Randall's claim seems to be correct.
