Live service and single player is not incompatible… Unfortunately…
Look at Hitman (2016 and forward), all require an online connection to play, and release new stuff monthly.
Many of Ubisofts games also require an online connection despite being fully single player, and you can even buy currency for the in-game single player shop with real money… What used to be a cheat code is now a microtransaction.
SSD longevity seems to be better than HDDs overall. The limiting factor is how many write cycles the SSD can handle, but in most cases the write endurance is so high that it’s unreachable by most home/NAS systems.
SSDs are however really bad for cold storage, as they will lose the charge stored in their cells if left unpowered too long. When the SSD is powered it will automatically refresh the cells in the background to ensure they don’t lose their charge.
