Like my fellow commenter, I also do have a few drives with over 50k head hours on them that still work fine, but I also had probably more than half a dozen drives fail on me or break (not including Sandforce SSDs, that'd be unfair), including one that had all of my early projects on it. Really wish I had a backup of that.
Now I have a backup of everything and whenever I have to think about how much storage I need for something I always take that number and multiply it by three -- if it's only stored once or twice, it really can't be more important than /tmp.
- jsjohnst 6y agoInteresting for me, I’ve had two drive failures, both in the past year, but otherwise nothing for the past five+ years. Both were data center class drives (Seagate Exios) and died within the first 2 months of purchasing them. I have over 20 consumer grade drives with >50,000hrs of reported power on time, of which 3-4 are >70,000hrs. They constantly see writes, but I’m definitely not pushing max IOPs by no means on a regular basis. I’d say around 1-2% of the time they are under very heavy read/write activity, otherwise just constant appending of data at around 50Mb/sec across the entire RAID pool.
- darkr 6y agoThis is a pretty common pattern with disk failures - in my experience they either tend to fail in the first few months, or they make it for the duration.
