When areal density increases on a hard drive, the data becomes more compact. Areal density refers to the density of bits storage on the circular platters. When you measure the performance of a hard drive, apart from the RPM, you should also take areal density into consideration. Areal Density: Is 7200 RPM HDD Really Faster than 5400 RPM HDD?

Of course, if your laptop has good cooling performance, you can also install a 7200 RPM hard drive on it. 7200 RPM hard drives are mostly used on desktops. Note: Due to heat dissipation and portability requirements, notebooks generally use 5400 RPM hard drives. If you just use HDDs to back up data, 5400 RPM hard drives are enough capable of that. Therefore, from these aspects, 5400 RPM hard drives are superior to 7200 RPM hard drives. Higher rotation speed can shorten the average rotation latency time and actual read and write time of the hard disk, but it also brings negative effects such as temperature increase, increased motor spindle wear, increased working noise, etc.Īt the same time, if other factors remain unchanged, the increasing rotation speed means that the power consumption of the motor will increase, the more electricity is consumed per unit time, and the working time of the battery will be shortened. 5400 RPM Hard Drives' Advantagesĥ400 RPM hard drives' advantages are low energy consumption, low heat production, low noise, and longer lifespan.
Therefore, if you have enough money, I still recommend you to install OS or run programs on an SSD. Note: 7200 RPM hard drives can't perform as well as SSDs. For a 5400 RPM hard drive, its average rotation latency time is 60 × 1000 ÷ 5400 ÷ 2 = 5.56 milliseconds. Therefore, 7200 RPM hard drives are usually faster than 5400 RPM hard drives.įor a 7200 RPM hard drive, the time required for each revolution is 60 × 1000 ÷ 7200 = 8.33 milliseconds, and the average rotation latency time is 8.33 ÷ 2 = 4.17 milliseconds. Typically, the more the hard drive RPM, the faster the hard disk. 7200 RPM Hard Drives' Advantageħ200 RPM hard drives' advantage is the high performance. In this part, I will explain 5400 vs 7200 RPM hard drives to you. High-speed hard drives like 10,000 RPM hard drives are generally used in servers and the rotation speed of ordinary hard drives for home use is generally 5400 RPM or 7200 RPM. Therefore, the rotation speed largely determines the speed of the hard disk.ĭetailed Introduction to Hard Disk - Learn About It Now 5400 RPM vs 7200 RPMĬurrently, the speed of disks can be as high as 15,000 RPM. In general, the faster the rotation speed, the faster the hard disk can find files, and the higher the transmission speed of the hard disk. Therefore, the rotation speed is that of the motor spindle in the HDDs, which also stands for the maximum number of revolutions that the platters can complete in one minute. The magnetic heads move along the radial direction of the platters, coupled with the high-speed rotation of the platters at several thousand revolutions per minute (RPM), so that the magnetic heads can be positioned at a specified position on the platter for reading and writing data. All the platters are mounted on the motor spindle in parallel and each storage surface of platters is equipped with a magnetic head.
About Rotation Speed (RPM)Īs we all know, the HDD is mainly composed of parts like platters, read-write heads, a motor spindle, etc. If you are facing this problem, too, please read on to get answers.

Which one should I buy? - Many users report in forums that they don't know how to choose from 5400 RPM and 7200 RPM hard drives. However, when I looked at the drives for sale, I saw that a Seagate Barracuda 2TB at 7200RPM is about the same price as a Western Digital Blue 2TB 5400RPM. I understand that 5400RPM is quieter and more reliable than 7200, but it is also slower or should be slower. How different is the 5400 RPM vs 7200 RPM performance in the latest drives?.
