I see most of the people confused about the RPM of Hard Disk. So what is RPM basically? Its Revolutions per minute. It is a measurement to calculate the rotational speed of the hard disk. It affects the Latency of a hard disk. Latency is the delay for the rotation of the disk to bring the required disk sector under the read-write mechanism. Confused? Lets talk in lame language now. Basically, RPM decides the time that will be taken by the hard disk to access the data. It will affect the data transfer speed of your hard disk as well as the speed of the data to be accessed.
So for you, higher the RPM better will be the overall performance of your system. Most people are confused between 5400rpm and 7200rpm. The answer is not quite simple though. Its obvious that a hard disk with 5400 will be cheaper but it definitely will decrease your system's performance. If you have no money issues and you want great performance, you can go with 7200rpm or even maybe for 10000rpm or more. Now there are cons as well. The higher the RPM, the less will be your battery life. It will drain your battery faster and will cause more heating as well.

So it depends on you now that you understand the meaning of RPM, what you chose. I won't say which one will be better. Of-course it will depend on the person buying. For any more queries you can comment below.
