Soldered memory provides 2 advantages:
1. Higher frequencies
2. Greater reliability of the motherboard during shocks and increased vibrations.
There are also two main disadvantages:
1. It is impossible to increase memory if it is not soldered immediately to the address limit of the memory controller.
2. In the event of a failure of one chip, the entire laptop becomes inoperable without a reboiling this chip or replacement of the entire motherboard (in modern coproeconomics, most likely only the second at your expense) - and then the processor and many other things are also soldered, which is many times higher increases the price of the entire motherboard, although you only need the motherboard and working memory.
The meaning of wiring from the perspective of positive aspects is adequate, provided that the manufacturer is not insanely greedy, like all the current ones with an installed volume.
Those. for 2022, the current volume is only from 32GB. For 2023, this is already closer to 64GB in the business segment.
I don't mind soldered memory when there is enough of it and the difference in price between a smaller volume and a larger one exactly corresponds to the retail prices of approximately the same memory with exactly the same guarantee + 10% on top "for the work" of installation, BUT no more.
In reality, they meanly and deliberately limit the life of the product so that it becomes obsolete as quickly as possible. And versions with a larger volume are deliberately sold with a markup not of 10%, but of 300-400%, relative to the additional price compared to retail prices of the same memory and volume, and always with a longer warranty than theirs (usually 5-10 years , instead of 1-3 years as part of laptops).
