In a way it's even better, that SSDs [are said to] fail abruptly and entirely. You can then just restore from backups and go on. Whereas a failing HDD can leave you puzzled on e.g. whether it's a cable or controller problem instead, and possibly can even cause some data corruption which you won't notice until too late. -- With respect, Roman
