I can see a mention of SQLite and MySQL. Also worth mentioning since this can affect any system:

I wonder how Oracle handles this. Raw device/partition and its own FS business logic?

[masklinn]

Direct IO is the default for raw devices, and while apparently not the default otherwise IIRC it's pretty widely used by Oracle shops.

[elygre]

While oracle supports raw devices, and have their own reasonably good way of managing that, most installations I see used is files for storage.

(Which leaves the question of how oracle handles this unanswered, of course)
