maybe you have dirty/unstable power; or you download/stream like crazy. over the past 10 years, I have bought/used over 30 disks (not just for myself, but for the group, servers etc), only had 3 disk failures - 1 failed disk for a new laptop and got it replaced, 1 failed intel SSD, and another old 500GB mechanical drive (retired after SMART warnings, no data lost).
