1. The hard disk speed refers to the number of revolutions of the hard disk platter per minute, the unit is RPM. (RotationPerMinute). Generally, the rotation speed of hard disks reaches 5400RPM (5400 revolutions per minute), while some hard disks, such as Maxtor's Diamond series, reach 7200RPM.
2. The hard disk speed is expressed in revolutions per minute, and the unit is RPM. RPM is the abbreviation of Revolutions Per minute, which is revolutions per minute. The larger the RPM value, the faster the internal transfer rate, the shorter the access time, and the better the overall performance of the hard drive.
3. Rotation speed: Hard disks are usually calculated based on revolutions per minute (RPM, Revolutions Per Minute): This indicator represents the speed of the hard disk spindle motor (which drives the disk). For example, 5400 RPM represents the spindle speed of the hard disk. It is 5400 revolutions per minute. The current rotation speed of mainstream notebook hard drives is 5400RPM; desktop hard drives are 7200RPM.
4. Rotation Speed: This is the rotation speed of the hard disk motor spindle. The rotation speed is one of the key factors that determines the internal transmission rate of the hard disk. Its speed greatly affects the speed of the hard disk. At the same time, the speed of rotation speed is also one of the important indicators to distinguish the grade of hard disk.
5. Rotational Speed or Spindle speed is 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.
6. RPM hard drive and 5400 RPM hard drive refer to how many times the hard drive rotates per minute. Difference: There are three main types of transfer for home hard drives, 5400 rpm, 5900 rpm and 7200 rpm. The higher the RPM, the faster the speed. At present, the fastest home hard drive is 7200 rpm.
There is no question whether the mechanical hard drive speed is 7200 or 5400. Judging from the recording and storage speed of the hard disk, 7200 is better. From the perspective of hard disk recording stability and long-term performance, 5400 is better. The 7200 focuses on general storage. The 5400 focuses on video surveillance recording.
change. According to Master Lu’s hard drive information query, the mainstream mechanical hard drive speeds are mainly divided into 5400 rpm, 5900 rpm and 7200 rpm. Among them, 5-inch hard drives have 5400 rpm and 7200 rpm speed products, and 5900 rpm speed products are only available on 5-inch mechanical hard drives. Appears, mainly used by NAS storage hard drives.
Transformed desktop hard drive: 90-190MB per second. The read and write speed of the hard disk is mainly determined by the rotation speed: 5400 rpm for laptop hard drives and 7200 rpm for desktop hard drives. The corresponding read and write speed of the hard drive is usually 5400 rpm notebook hard drive: 50-90MB per second.
If you check the hard disk speed through the system, click Start---Programs---Accessories---System Tools---System Information---Select in the left box--Components---Storage, then all The disk information is available. If there is no rotational speed, you can check the hard disk's specific information online.
GB. Hard drive is one of the main storage media of computers. It is composed of one or more aluminum or glass discs. The discs are covered with ferromagnetic material. Capacity is the most important parameter of the hard drive. Hard drives are divided into solid state drives (SSD), mechanical hard drives (HDD), and hybrid hard drives (HHD).
1. Currently, there are four main hard drive speeds: 5400, 7200, 10000 and 15000 rpm, among which 7200 and 5400 rpm are the most common. In addition, there are some rare speeds, such as 10,000 rpm solid-state drives and 15,000 rpm enterprise-class hard drives. When choosing the hard drive speed, you need to weigh it based on your personal needs.
2. Common hard drive speeds currently on the market generally include 5400rpm, 7200rpm, or even 10000rpm. In theory, the faster the speed, the better. Because higher rotational speed can shorten the average seek time and actual read and write time of the hard disk. However, the faster the speed, the greater the heat, which is not conducive to heat dissipation. The current mainstream hard disk speed is generally above 7200rpm.
3. Detailed explanation of mechanical hard drive speed: from 5400RPM to 15000RPM. Mechanical hard drive is a common device used by computers to store data. Its read and write speed and stability have a great impact on the overall performance of the computer. Among them, the rotation speed of the hard disk is a major indicator of hard disk performance.
4. The hard disk speed is generally 5400rpm, 7200rpm, or even 10000rpm. Desktop computers generally run at 7200 rpm. The rotation speed affects the time it takes your machine to read data. The higher the rotation speed, the faster the access speed, which can save time.
At present, there are four main hard disk rotation speeds: 5400, 7200, 10000 and 15000 rpm, among which 7200 and 5400 rpm are the most common.

Classification of rotational speed The rotational speed of mechanical hard disks can be divided into different grades such as 5400RPM, 7200RPM, 10000RPM, 15000RPM, etc. Among them, 5400RPM and 7200RPM hard drives are commonly used, while 10K and 15K are usually used in high-performance applications such as servers and workstations.
Depends on the type of hard drive. According to different working principles, hard drives are divided into mechanical hard drives and solid-state hard drives. The most common mechanical hard drive currently is Winchester mechanical hard drive. If used on a laptop, 5400 has the best speed, and if used on a desktop In the field, the speed of 7200 rpm is the best.
Generally, 5-inch (desktop hard drives) are 7200 rpm, and there are also 5400 rpm, which are marked on the hard disk. The 5-inch (laptop hard drive) is 5400 rpm. The hard disks on the server have 10,000 rpm and 15,000 rpm.
The current mechanical hard drive with the highest rotation speed can reach 15,000rpm (15,000 revolutions per minute) and is usually used in servers. Hard drives currently used in home products are usually 5400rpm or 7200rpm. Generally, hard drives with high rotational speed are noisy and more expensive. There are currently 5 hard drives with different speeds.
