Completely wrong - your SSD will die in 3-4 years so thats not 'virtually unlimited'. Laptops have lasted 10 years without issue before adn now its a lot less than half. SSD's are generrally 'on-board' chips so a hardware swap out is impossible. My experience of an office full of SSD laptops says they die quickly, and very often - to the point that field techs only get HDD laptops.

Disagree - anyone who uses a laptop with SSD daily will see short life. SSD's dont just lose portions and then ignore the dead parts and use the rest. They just fail, lose a big chiunk of the OS (which is the bit that is R/W most often) and go 100% dead.

Incorrect - you get large dead patches in the chip and you lose files and if its the OS then you lose the entire contents. SAt least with an HDD, it has a distinct are for the FAT/NTFS/APFS table, but on an SSD , the most important part 9which says where all your files are) is as unreliable as the rest.
Never ever ever use an SSD as a backup.
