Question: What Does Hard Drive RPM Mean?I'm looking at the new MacBook Pro and I see there are hard drive options with different RPM listed - what's the difference?
Asked by Gary C.
RPM stands for “revolutions per minute”. A standard hard drive has a spinning disc inside of it – RPM measures how many times that disc spins in a minute. As RPM increases, the speed of your hard drive also increases. So a hard drive with a higher RPM represents a faster hard drive. The recently released MacBook Pro 15 (Feb 2011) includes a 750GB 5400 RPM hard drive or a smaller, faster 500GB 7200 RPM option.
