What is the difference between a 5400 and a 7200 RPM hard drive? • Pureinfotech

If you’re building a Network Attached Storage (NAS), new computer, or upgrading a hard drive (HDD) on your system, it’s important to understand the difference between a 5400 and 7200 RPM hard drive.

The performance of a hard drive is measured by the speed at which data can transfer from the disk that stores the bits to the computer (known as data throughput). Usually, the higher the disk density and revolutions per minute, the better the performance. That doesn’t mean, however, that storage spinning a lower RPM should be completely ignored.

5400 RPM vs 7200 RPM

Although today you can find hard drives spinning up to 15000 RPM, the most common drives for desktops and laptops are between 5400 and 7200 RPM.

Former hard disk spinning drives operating at 7200 RPM provide fast read and write speeds and are more suitable for running operating systems, faster program execution, and file transfers.

Note that they can be expensive. They generate more heat, consume more electricity, make more noise, and have a shorter lifespan than drives at lower revs.

Then there are HDDs that spin at 5400 RPM and as expected they offer slower file transfer speeds, but they use less power (thus less heat and quieter) and they use less power. worse. While most people will immediately ignore these drives, they are a good choice for storing large files.

While the 7200 RPM hard drive is definitely faster than the 5400 RPM drive, the 5400 RPM drive offers an average of 100 MB/s read and write speeds while the 7200 RPM drive offers 120 MB/s average read and write speeds. If you’re trying to decide, consider that both drives are virtually identical, but the difference is that the 7200 RPM drive is about 20 percent faster than the 5400 RPM drive.

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

Select hard drive

As for the competencies and brands you get, it depends on your interests and what you’re trying to accomplish. However, among the popular brands you can find “Western Digital” and “Seagate” and each brand offers different hard drives for each case.

For example, if you want more storage or you’re trying to build a new system, you can use one of the following hard drives:

Besides, Seagate BarraCuda 2TB is one of the best selling 7200 RPM internal hard drives and it costs only $47.

If you’re building a NAS or adding more capacity to your system for long-term file storage, you should consider purchasing the following hard drives:

In case you are going to build a low power server, it is best to use a 5400 RPM drive.

These are just some recommendations, but there are many manufacturers, capacities and technologies that you can choose from. See more drives at Amazon.

This guide focuses on traditional spinning disk hard drives because the focus here is on drives to store large amounts of data. Of course, hybrid drives and Solid State Drives (SSDs) offer better performance, but they don’t offer much capacity and they’re still quite expensive.
