How can a hard drive do multi task?

Answer 1

yes, a hard drive can multitask, it head can make about 60 reads and writes every second, like if you were to open say 5 documents at the same time the hard drive has to locate them all which sometimes it will multitask to find them. Or if you are listening to music or watching a video and you was to open a couple of documents the hard drive would have to multitask and send the video or song to the RAM before it finds the files but it all happens in a split second so it is like it is multitasking, and think about the next time you copy something one by one onto the hard drive instead of copying it all at once it has to multitask to copy them one by one but it would slow it down a bit because the hard drive head would be continually jumping about to write it to the disk but most of the time something will be sent to the RAM to keep up the speed of the hard drive and to keep it from becoming hot because it causes more heat when the hard drive heads have to keep jumping about and to help pull some of the strain of the hard drive which is why it always better to have more RAM because it means more can be sent to it while the hard drive consentrates more on other tasks like writing something while you are listening to music. Where as if you have less RAM sometimes the hard drive has to use itself as virtual RAM so obvisouly you are putting more strain on it because then it really would be multitasking
