OK, it's not the same kind of thing, then. It's prefetching, not disk

Had you actually bothered to check the cited reference (Google just found it
easily by title for me), you'd have found that it's a two-stage process.
The first stage is the one Maxim described; the second runs periodically to
reorganize data on the disk to optimize the operation of the first.
