Forget ssd wear out. It doesn't happen in the real world. Just use the computer regardless how much it will write. You will replace any computer due to old age before any ssd is worn out.
If you ask for proof: look around for complaints about broken down SSDs. There are next to none. There are less complaints about broken down SSDs than there were complaints about broken down spinning hard disks when spinning hard disks were the only bulk memory available.
