If you plan lớn build a Network-attached Storage (NAS), a new computer, or tăng cấp your system’s hard drive (HDD), it is crucial to understand the differences between 5400 và 7200 RPM hard drives.

The hard drive’s performance is measured by the tốc độ the data can transfer from the platters storing the bits to the computer (known as data throughput). Usually, the higher the density of the platters & revolutions per minute translates into higher performance. However, it doesn’t mean you should ignore a storage drive spinning a lower RPM.

5400 RPM vs. 7200 RPM


Although nowadays, you can find hard drives spinning up to lớn 15000 RPM, the most popular ones for desktops và laptops are between 5400 & 7200 RPM.

Historically rotating platters hard drives that operate at 7200 RPM offer faster reads & write speeds & are more suited to run an operating system, execute programs quicker, & transfer files.

The caveat is that they can be costly, generate more heat, consume more power, produce more noise, và lifespan can turn out to lớn be shorter than drives that spin at lower revolutions.


Then there are the hard drives that spin at 5400 RPM, và as expected, they offer slower file transfer speed, but they use less power nguồn (therefore less heat và quieter) và are less expensive. While immediately, most people will ignore these drives, they are a good choice for storing large files.

Although 7200 RPM hard drives are faster than 5400 RPM drives, 5400 RPM drives offer an average of 100 MB/s read và write speeds, while 7200 RPM drives deliver an average of 120 MB/s read & write speeds. If you are trying khổng lồ decide, consider that both drives are virtually identical, but with the difference that a 7200 RPM drive is around đôi mươi percent faster than a 5400 RPM drive.

If you want performance, you should consider the 7200 RPM hard drives. However, if the goal is to store files (for example, on a NAS or low-power server), you should consider the 5400 RPM drives.

Choosing hard drive

As for capacity và the brand you should get, it is up to lớn your preference & what you are trying to lớn accomplish. However, among the popular brands, you can find “Western Digital” & “Seagate,” và each brand offer different hard drives for each situation.

For instance, if you want to địa chỉ more storage or you are trying khổng lồ build a new system, you may go for one of these hard drives:

Also, the Seagate BarraCuda 2TB is among the best-selling 7200 RPM internal hard drives, priced only at $50.

If you plan lớn build a NAS or địa chỉ more capacity to lớn the system lớn store files long-term, you should consider getting these hard drives:

If you plan to lớn build a low-power server, it’s best to lớn use 5400 RPM drives.

Around the web, you may be able to lớn find many manufacturers, capacities, và technologies. These are just some recommendations.

This guide is focused on traditional rotating platters hard drives as the focus here is on drives to store a large amount of data. Of course, hybrid drives và Solid State Drives (SSD) offer better performance, but they do not provide as much capacity and are still quite expensive.
