Since many hardware systems also prefetch the neighbouring cacheline(s) when a particular cache-line is fetched, more important data will also be prefetched.
However, we note that because the characteristics of I/O devices are such that they operate most efficiently when fetching big blocks, the effectiveness of sequential prefetch depends very much on whether the logically sequential pages are physically sequential on the I/O devices.
A prefetch is unnecessary if the line is already in the cache (or is currently being fetched), and is useless if it brings a line into the cache which will not be used before it is displaced.
Recall that from a given disk, one can only prefetch blocks that are stored on it, while evictions can be from any disk.
