gollark: It has 68513 hours of power on time, 1986 power on/off cycles out of a rated 10000, and 4 "elements in grown defect list".
gollark: Ah, according to the data I got off it, my drive was manufactured in 2012. Which is something like threeish years after the server came into existence, as far as I know.
gollark: Also, there was some admittedly small-scale testing by some computer review company and SSDs could mostly go significantly beyond their endurance ratings and manage hundreds of terabytes written. But also did tend to fail suddenly and inexplicably instead of having a graceful failure.
gollark: Store the hashes of things, expect more computing power later.
gollark: I mean that most of these things (HDDs *and* SSDs) will either fail quickly or probably run for quite a while.
