SSDs in raids famously all failed at once. Spinning disks basically don't, outside of (typically) firmware faults. Out of 100000 spinning disks I've managed, I've never had them fail at the same time.
Mechanical things don't fail as evenly as digital things.
- pixl97 3y agoAs someone that has set up a lot of NAS devices, we're talking thousands of disks over the years, I would not put my money on your statement. There are a lot of simultaneous failure modes. HP had one in SMART firmware that killed disks at some fixed number of hours. There are also temperature excursion events that can lead to arrays failing within 10s of hours of each other, not enough time to do a full rebuild of a single disk. Seagate had really crappy 3/4 tb disks that loved to fail rapidly and nearly all at once.
- dragontamer 3y agoIntel also had a famous bug / 'feature' where the SSD refuses to respond after a fixed number of writes. If all your drives were Intel and part of the same array, they'd all fail at exactly the same time. Reliable storage is hard.
- b112 3y agoSo your examples of failures include a firmware example, which I said "outside of", and an example where the drives were abused? And another poster os talking about SSDs? Sigh
