I also don't know about literature on this phenomenon, but i recall HP had two different SSD recalls because when the uptime counter rolled over, they would fail. That's not even load dependent, just did you get a batch and power them on all at the same time. Uptime is too high causing issues isn't that unusual for storage, unfortunately.

It's not always easy, but if you can, you want manufacturer diversity, batch diversity, maybe firmware version diversity[1], and power on time diversity. That adds a lot of variables if you need to track down issues though.

[1] you don't want to have versions with known issues that affect you, but it's helpful to have different versions to diagnose unknown issues.
