This is a good example of how scale can bias your view! :-D

Personally I share the same experience: In the 30 years I've been using personal computers at home and work, only 2 disks failed on me, one was an error on my part during an OS upgrade and the second was an external disk that physically fell off my bed while I had it plugged into my notebook. So both of these weren't really those random failures.

On the other hand, while working in an IT infra team of a 60 developer company with 4 racks full of servers for 3 years, we'd get to see about one failed SSD per 2 months and 2-3 failed disks or SSDs per year in servers.

During the 1 year I worked for the IT infra team at a smaller hospital of a medium sized city with a large VDI environment and two HP EVAs in a two datacenter configuration each, we'd get 3-4 disk failures per week. Those had over 140 disk per storage each and were approaching the end of their support life, being around 5 years old, so the failure ratio started to get higher.
