Here's a report by folks who do lots of HDDs and SDDs: https://www.backblaze.com/blog/backblaze-hard-drive-stats-q1-2021/ The gist, for disks playing similar roles (they don't use yet SSDs for bulk storage, because of the costs): 2/1518 failures for SSDs, 44/1669 for HDDs. I'll leave the maths as an exercise to the reader. Cheers -- t
