How to Check Hard Drive RPM (Revolutions per Minute): Hard drives are particularly popular for their low prices as they provide large storage volumes at a comparatively cheaper cost. Any standard hard disk consists of a moving part i.e. a spinning disk. Due to this spinning disk, the property of RPM or Revolutions Per Minute comes into play. RPM basically measures how many times the disk will revolve in a minute, hence measuring the speed of the hard drive. Many computers nowadays contain SSDs which do not have any moving component and therefore RPM makes no sense, but for hard disks, RPM is a crucial metric to judge their performance. Consequently, you must know where to find your hard disk RPM in order to determine if your hard disk is working fine or if it needs to be replaced. Here are a few ways in which you can find your hard disk RPM.

Your hard drive has a label with the exact RPM of the drive. The most reliable way to check your hard drive RPM is to check this label. It’s an obvious way and you will need to open up your computer to find the label. You will probably not need to pull out any part in order to see this label as in most computers, it is easily insight.

What’s the best RPM on a hard drive?
For general-purpose computers, an RPM value of 5400 or 7200 is enough but if you are looking at a gaming desktop, this value can be as high as 15000 RPM. In general, 4200 RPM is good from the mechanical point of view whereas 15,000 RPM is recommended from a performance perspective. So, the answer to the above question is that there is nothing like best RPM, as the selection of hard drive is always a trade-off between price and performance.
