My time frame is about since end 90s to now. I saw more failures in general in the olden days. I have quite a lot of rented servers at traditional hosters or Colo that have not been down outside kernel security updates for 10+ years. No hardware issues. I am now swapping them out for new servers which cost less for more, but hardware wise they have been pounder hard for 10 years without issues. All hotswap raid5 drives, so when broken, they or us just fixed it without downtime.
