How much faster is a 7200rpm hard drive than a 5400?

How much faster is a 7200rpm hard drive than a 5400?

But today's most common RPM rates, in both laptop and desktop PCs, are between 5400 and 7200 RPM. Given two identically designed hard drives with the same areal densities, a 7200 RPM drive will deliver data about 33% faster than the 5400 RPM drive.

Are 5400 rpm drives more reliable?

Traditionally 5,400 RPM drives have demonstrated greater reliability. The parts are under less stress because they do the work slower, they use less power usually, and they generate less heat. 7,200 RPM drives have classically been chosen over 5,400 RPM drives only for faster performance.

Does hard drive RPM matter?

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.

What is the data transfer rate of a 5400rpm hard drive?

Really good hd's can transfer data at around 200 MB/sec , reading from a disk. A baseline for good harddrives of about 1TB in capacity and spinning at 7200 rpm, would be about 150MB/sec. 7200 rpm drives transfer data about 33% faster than 5400 rpm drives. 33% of 150MB/sec = 49.5 Mb/sec.
