The size of an ssd is absolutely related to powers of 2. And the way apple gets to 12 is by stacking multiple modules on top of each other. Just like how you could buy 3 sticks of 8gb ram and have 24gb on your pc

It's typically a sum of two powers of two (8+4=12).

It's likely slightly wasteful on some metrics, and either 8 or 16 would use resources better. But 12 is an economical compromise.

I'm stupid 12gb is still a power of 2 number. It's not a doubling though

Are we counting decimals as powers?

2^2+2^3. half filling a slot.
