What is meant by arm-stickiness?..

Answer / guest

If one or a few processes have a high access rate to data
on one track of a storage disk, then they may monopolize
the device by repeated requests to that track. This
generally happens with most common device scheduling
algorithms (LIFO, SSTF, C-SCAN, etc).

High-density multisurface disks are more likely to be
affected by this than low density ones.
