What is seek speed in HDFS and why is it no longer going to be important?


Seek speed is the speed i.e. rpm (revolutions per minute) a magnetic drive or an optical reader rotates to read the data from those HDDs Hard Drive Disks; This speed is dependent on the motor's rotation speed which directly impacts reading and writing of data into these devices. The speed of the motor is limited as it is powered by 12V capacity and also should not drain the battery if they are in the laptops. However, more and more newer age laptops and devices are now using SSDs Solid State Drives which are not only faster because the speed is not dependent on the revolving motor and also does not drain your laptops battery charge. This allowed the laptops to be less bulkier/heavier and reduce the overall battery size to make it a little lighter.
