Assuming your math is correct (and I have no reason to doubt that it is) a mass of 10^16 kg would actually be a pretty small moon or moderately sized asteroid. That's actually roughly the mass of Mars' moon Phobos (which is the 75th largest planetary moon in the Solar System).

I was thinking of 10^16kg diamond storage inside a larger SSD that’s the size of a large moon, similar to how a real SSD has data stored in tiny little slivers of silicon inside a much much larger device.

I should have explained that one better. It’s easy to imply such details to keep text shorter.

Out of curiosity, why did you say planetary moon? Is there any other kind?

Dwarf planets sometimes have moons (e.g. Pluto)

Some large asteroids have moons too.
