What does HDD 7200rpm and 5400rpm mean?

The analysis is as follows: Generally speaking, 7200 rpm than 5400 rpm hard disk must improve the performance of the computer to varying degrees, the faster the hard disk is running, the greater the power consumption, and the heat dissipation will be much higher than that of the lower speed.

With the same configuration of the notebook, the temperature of the 7200 rpm hard disk is higher than that of the 5400 rpm, and the read and write speed is also relatively fast. Compared with 5400 rpm hard drives, 7200 rpm hard drives can better meet the needs of users in terms of transfer rate.

A 7200** per minute) drive takes 60 1000 7200 milliseconds per rotation and has an average rotation delay of milliseconds (on average, half a revolution).

According to the same calculation, the average spin delay of a hard disk of 5400** per minute is 60 1000 5400 2 ms. Compared with the two, 7200 rpm is theoretically 15% faster than 5400 rpm, but the actual speed is only less than 10% faster than the latter, which is far from the one-third that many people expect.

Both of these values represent the rotation speed of the motor spindle in the hard disk, which is the maximum number of revolutions that the hard disk platter can complete in one minute. That is, the speed of the 7200 rpm hard disk is 7200, and the same is 5400 rpm for 5400 rpm. At present, the speed of mainstream desktop hard disks is 7200 rpm, most of the mainstream notebooks are 5400 rpm, taking into account power consumption, heat dissipation, noise, etc., and mid-to-high-end notebooks have also reached 7200 rpm.

In large computers such as servers, SCSI hard disks can reach 10,000 revolutions or even 15,000 revolutions, and the performance is far from comparable to that of home desktops. Hope it helps!

Refers to the speed of the hard disk, the higher the speed, the faster the hard disk read speed. 7200 rpm.

It is the speed of the hard disk, relatively speaking, the higher the speed of the hard disk, the better the performance.

Hard disks generally have 4400rpm, 5400rpm and 7200rpm, the higher the number, the faster the speed.

The difference between 5400 rpm and 7200 rpm is the different speeds.

The difference between 5400 rpm and 7200 rpm is that the speed is different, 7200 rpm is faster and faster in terms of read and write speed. 5400 rpm and 7200 rpm indicate the speed of HDD, which is more reliable than SSD, and it is recommended to save important files in HDD. Splitting.

Computer hard drives

A computer's hard disk is the most important storage device for a computer. Hard disk (called hard disk in Hong Kong and Taiwan, English name: harddiskdrive for abbreviation, HDD full name Winchester hard disk) is composed of one or more aluminum or glass discs.

These discs are covered with ferromagnetic material.

The vast majority of hard drives are fixed hard drives that are permanently sealed and fixed in the hard drive. Early hard disk storage media were replaceable, but today's typical hard drives are fixed storage media that is encapsulated in the hard drive (except for a filter hole to equalize the air pressure). With the development, removable hard drives have also appeared, and they are becoming more and more popular and varied.

The capacity of a hard drive is measured in megabytes (MB) or gigabytes (GB), 1GB = 1024MB, 1TB = 1024GB. However, the hard disk manufacturer usually takes 1g = 1000MB when the hard disk is weighed by the standard rock source brigade, so the capacity we see in the BIOS or when formatting the hard disk will be smaller than the manufacturer's nominal value.

In recent years, with the continuous development of technology, more and more people have begun to understand and use computers. Hard drives are an important choice factor when buying a computer, as different drive speeds and** will have an impact on your computer's performance and experience. Therefore, this article will introduce the advantages and disadvantages of 5400 rpm hard drive and 7200 rpm hard drive in detail for users' reference.

First, let's take a look at the 5400 rpm hard drive. Compared to the 7200rpm HDD, the 5400rpm HDD is more energy-efficient when used because it spins slower and reduces energy consumption. In addition, the 5400 rpm hard drive** is more affordable than the 7200 rpm hard drive, which can meet the needs of some users with a limited budget.

However, it should be noted that the 5400 rpm hard drive has a slower read speed and may experience stuttering, especially when dealing with large amounts of data.

Next, let's take a look at the 7200 rpm hard drive. Compared to a 5400 rpm hard drive, it has a faster read speed and can handle large amounts of data better. In addition, the 7200 rpm hard drive has better durability and is more suitable for long-term use, so it is more common in the business environment.

However, the 7200 rpm hard drive** is relatively high, which can be overwhelming for some users on a budget.

To sum up, the choice of hard drive should be decided according to the user's needs and budget. If you need to process a large amount of data or need higher read speeds, a 7200 rpm hard drive may be more suitable. If you're on a budget or just for everyday use, a 5400 rpm hard drive may be a more practical option.

Of course, before making a decision, users should also consider other factors such as storage capacity and brand credibility to ensure that they choose the best drive for themselves.
