For example, if you write out a block to disk, that block may wait for milliseconds in the cache... the processor wants to see if an additional block will be written to the file. If another block is written, a similar wait may occur. When the wait time expires, whatever blocks that were written to cache... are dumped to the actual disk. A disk read may cause an entire track to be read into the cache, the thought being that another read from the track could be eminent. My WD Green disk drive claims that after a certain time with *no* disk access, the disk heads will be "unloaded". The preceding are sample things that a modern processor-controlled disk drive may do. I'd sure like to understand *all* the algorithms used by the drive to make such decisions!!! -- numerist at aquaporin4 dot com
