I build and/or service all of my PCs, servers and laptops. I never had a single component die on me. I still have my first 128GB Samsung SSD serving as a boot drive in my NAS. Sometimes I buy used parts. Sometimes I sell used parts. I never had any problems with DOA parts no matter if new or used. I'm always careful with static electricity (no sweaters, carpets, cats etc near components). Maybe I'm just lucky or maybe some people are not careful enough with sensitive electronics.
