This is why I hate M.2 drives. They are so expensive, that you can only afford a small capacity one, that fills up quickly, but Apple takes it a step further, eliminating the M.2 slot entirely, and soldering the memory chips directly to the motherboard, so you don't even have the option of upgrading it to a higher capacity one, later. Apple basically forces you to buy a fully maxed out Mac right out of the gate, and Apple has always been known for overcharging for upgrades. If you don't buy it fully maxed out at the start, your only option is to buy a new Mac, in a year or two, when yours becomes obsolete because you didn't order it with enough options.
