Drive Speedometer is a program to help monitor the current read and writes speeds of your hard drives. The program uses the Windows performance counters to pull the information.
When your system is running slow yet your CPU usage and memory usage are fine, it is normally the hard drive being maxed out. Now you will be able to keep an eye on the hard drive performance.

When a drive is slowly dying it will run slower and slower. Being aware of what your normal drive speeds are and seeing those speed drop over time is a great indicator it is time to replace the drive.
