Summary

[edit]
Description From a (not so) past era comes this engineering beauty. It's disk is as small a 1€, it's format is Compact flash and it's total capacity was 4Gb. This one is from an iPod Mini teardown. The iPod Mini was designed when physical micro harddisk where cheaper than 4Gb on a chip (SSD). Today pocket memories are so common that you can get any USB pen about 32Gb for less than 30€.

This image has currency in it to indicate scale.

Using coins for scale is discouraged as it will require people unfamiliar with them to look up the dimensions or guess, both of which defeat the purpose of the object in the first place. Coins can also reinforce a geographical bias, and some coins' designs are copyrighted.

Ideally, a photograph should include a ruler with the subject (example) or an added scale marking. SI ("metric") units are the most commonly used worldwide (see meter and centimeter).
