No, it doesn't take years and the testing is performed, roughly, as I just described it.
They build a test rig with 10,000 drives which they run continuously producing a total "drive hours" count and then wait for the first one or two or ten drives to fail.
X failures / 10,000,000 drive-hours will give you your MTBF, etc. ... and only takes ~40 days given a 10k drive test rig.

- Tadpole9181 2mo agoYes, this is one of the hacks they use that are fundamentally inaccurate due to confounding variables like bathtub curves and different issues causing early failures and long-term failures... Because, otherwise, they would need to run those drives for years and years with reasonable cycling and read/write pressure to report accurate numbers based on real world failure rates in real conditions.
