I think preconditioning is also dependent on the type of data written. Large files by all accounts do not degrade a drive in the same way that small files do.

Also reviewers tend to omit benchmarks with mixed random read and write tests, which result in significantly reduced IOPs.

Here are a few extracts from various industry presentations.

The last image appears to show that different drives require different preconditioning. Drive size and over provisioning allowance would also have a significant impact.

The second implies that the impact of mixed reads/ writes is significant, yet mostly ignored.

Lastly the first image implies at least three hours of heavy writing is required to get a drive into s steady state.
