Manufacturing process has bearing on firmware is flashed to an EEPROM.
SSDs do not optimize for small frequent writes as a) the blocks a strictly limited number leveltimes, fancy wear levelling algorithms must calculate where actually put each write. b) to write a block already containing data a slow erase operation has to happen first and all data in that block gets erased. what SSDs do optimise for is lots of reads. Finally most other manufactures already included in their laptops for the, Apple was quite late to that party.
