CFM, standing for Cubic Feet per Minute, is a measurement of the amount of a material (usually a gas or liquid), measured in cubic feet, that passes through a given spot over the interval of one minute.
RPM, standing for Rotations per Minute, is a measurement of the number of full rotations (360 degrees) that something makes over the interval of one minute.
The difference between the two is that one is a measurement of Volume vs. Time whereas the other is Rotation Distance vs. Time.

1. ASSUMING AIR DENSITY AND FAN BLADE DIAMETER IS CONSTANT OR THE SAME --THE LATTER (1750 RPM) DELIVERS MORE CFM WHETHER BELT DRIVEN OR DIRECT COUPLED -- SAME HP RATING OF MOTOR. 2. 1250 RPM FAN CAN MATCH THE CFM OF 1750 RPM FAN --- CHANGE OR ADJUST THE PITCH OF 1250 RPM FAN BLADE. 3. 1250 RPM FAN CAN DELIVER MORE CFM THAN THE 1750 RPM FAN --- REPLACE FAN BLADE. 4. 1250 RPM FAN CAN DELIVER MORE CFM THAN THE 1750 RPM FAN --- REPLACE WITH BIGGER HORSE POWER.
cubic ft per hour or cubic feet per minuit the difference is time

RPM stands for Revolutions-Per-Minute, and is counted at the crankshaft. At 3000 RPM the engine is spinning twice as fast as at 1500 RPM.
The relationship between cubic feet per minute or cfm and cubic meter per hour or cmh is that there are approximately 0.59 cfm in 1 cmh. Similarly, 1 cfm is equal to approximately 1.7 cmh.
rated rpm is the maximum number of complete rotations that a rotor can rotate for every minute
If the abbreviations stand for cycles per minute and revolutions per minute, there is no difference.
NONE AT ALL.
Difference between Torque and load
Yes, you will see a difference in performance, read tests and write tests. As rule, 5400 rpm hard drives are faster and perform better.
7,200 revolutions per minute compared to 5,400 revolutions per minute.
