Every day, according to my frustrated genius bar guy, when one sent my logic board into the trash just out of Applecare. SSDs have a finite lifespan of about a thousand writes. The filesystem mitigates the effects of wear by various strategies but it still isnt a lot no matter how you spread it around. Rossman isnt incorrect, people pay him good money to try to repair Apple’s mistakes all day long. Soldiering the ssds to the board serves only two purposes: 1, its cheaper to produce, and 2, it limits the lifespan of the machine to its fastest wearing component. When pressed Apple gave the excuse that it was required for the highest speed performance, though that was slower than plenty of non-soldiered drives outside the PR bubble.
The complaining about this took place about 6 years ago when Apple got really aggressive about user-hostile design and cost engineering every nickel possible out of their production. Didn‘t matter. Apple doesnt care and neither do the kids. Every year fifty million more buy whatever is being sold.
