It depends on the way in which your computer buffers data.  Many computers
double buffer data.  That is they read it in as disk blocks and keep it
in main memory.  When you ask for the next sentence, they get it from the
block of memory which contains the whole disk block, avoiding I/O.

If double buffering is not used on your computer, you would save time as
well as wear and tear by emulating double buffering.
