Internal hard drives power consumption has been an important issue not just for desktop PC hard drives but to mobile devices as well,  although smaller devices often consume less power than larger drives.  One vital innovation is in the area of controlling the seek time of the hard drives.  Seek time from internal drives ranges under 5 milliseconds(ms), for servers and up to 9ms for desktop drives.  Audible noise is also important for certain applications, such as digital audio recording.  Another issue is the shock resistance, where it is a key concern for laptops.  Some laptops have shocks sensors that parks the disk heads when the laptop is accidentally dropped.
