What does the hard disk do?

Hard disk is the most important external memory of computer, which has the advantages of large capacity and high speed.

the hard disk has many indicators, it is a mechanical part, and the indicators include spindle speed and seek time. In terms of performance, there are storage per disk and internal transmission rate.

At present, the hard disk subsystem is the biggest bottleneck limiting the performance of the computer. Although the hard disk is a fast external memory, its speed is really slow compared with the CPU memory.

as a result, universal hard disk, RAID and iRAM appear constantly.

after the hard disk speed is increased, the overall performance of the system will be greatly improved.

Anyone who has seen iRAM (using memory as a virtual hard disk) will feel this way. The speed of 3Gb/s can't catch up with any hard disk, and the time to enter the system, games and programs is obviously reduced, and the test score is obviously improved.

What is the main function of the computer hard disk

Among all computer components, the hard disk is a data container for storing the software, movies, games, music and so on that we usually install. In a computer, the role of hard disk is second only to CPU and memory. His main function is to store the operating system, programs and data.

with the continuous development of IT industry, the volume and capacity of computer hard disks are upgraded at a very fast speed. Due to the improvement of the update speed of computer accessories, a large number of second-hand hardware has appeared, and second-hand hard disk is one of them. At the same time, there are more and more brands of hard drives, such as ASUS hard drives and Seagate hard drives. And there is a mobile hard disk which not only has the function of hard disk but also is convenient to carry. At the same time, the appearance of hard disk box also provides convenience for carrying. Greatly meet the needs of users.

actually, the hard disk is also a very fragile device in the computer, which needs to be taken care of. Because even a slight vibration may cause damage to the hard disk. After the hard disk is damaged, it can be sent to a professional hard disk repair point for inspection, but the data on it is likely to be lost.

If you want to edit pictures, play games or listen to music on your computer, a large-capacity, fast and reliable hard disk is very important. Because in the process of operation or surfing the Internet, a large number of temporary files may be stored on the hard disk, which affects the running speed. Therefore, it is necessary to defragment and repair the hard disk regularly. When sorting or repairing, if data is lost, data can be retrieved by hard disk data recovery.

What exactly does a computer hard disk do?

Let me give you an analogy: a hard disk is like a warehouse. If there are many goods, it requires a large warehouse, but if there are few goods, it is meaningless to have a large warehouse. Just put it down. Memory is like the corridor leading to the outside of the warehouse and the place where goods are temporarily stacked. Small memory equals small corridor, and goods can only be carried in small quantities. Processors are like porters, and powerful processors are like loaders. The quantity of goods that can be loaded at a time is large, and the speed is fast. Dual-core can be understood as two loaders, and the frequency of CPU is like the speed of loaders. . . That's about it!

What's the function of the size of the hard disk?

The hard disk is the external memory of the computer, which is used to store the data in the computer (movies, files, games, programs, systems, songs, etc.). The data of the hard disk can be read and written, and it won't be lost when power is cut off. The size of the hard disk represents how much data your computer can store. The large hard disk can store more data, while the small one is relatively small. The size of the hard disk is limited by the support of the motherboard. The 16G hard disk is too big, which is a kind of idle waste of computer resources. I suggest you make good use of this space to back up the data of the hard disk, which is good for yourself.

What's the function of a good computer hard disk?

If the hard disk is good. .

1. The calorific value is small, so the computer will not be very hot. . Especially the notebook is best to use. . .

2. It is fast when storing or reading. . Especially when copying some large files, it is obviously felt.

3. The speed of the hard disk also affects the running speed of the computer. .

I hope this information can help you. . .

please accept it if you are satisfied. thank you. . . .

What role does the hard disk play in the host

The function of the hard disk is to store and read data. For example, when you run a game program, you frequently read data from the disk, and the reading of data is related to the speed of the hard disk. The faster the speed, the more data you read, so it is very necessary to choose a good hard disk, but it is not the only factor. It also depends on the running speed of the CPU, etc. I hope it can help you! ! !

what are the benefits of hard disk?

hehe! This problem is easy to understand. There are many things stored in the hard disk.

It is really inexhaustible for home users, but do you know how big the hard disk is needed for the monitoring equipment in the hotel? Generally, it is at least 8G, which is used to store videos for one to three months.

is it better to fill the hard disk or empty it more?

There is no such problem. It's all the same except that drive C should be as empty as possible.

In particular, drive C only has system files, and nothing else is installed, and there are dozens of gigabytes empty. Is this good?

drive c belongs to the system drive letter, so generally you can't put anything else. The virus mainly attacks drive C. If it is infected, it will be difficult to handle, and the system files are all in it. If you put more

drives in the system, will the capacity of each drive be even? What are the benefits?

There is nothing even and uneven, it is just a warehouse for storing data. Don't think so complicated.

What can an external hard disk do?

Can you move the hard disk? Of course, you can connect to other computers. Hard disks have a large capacity and can store more things, so it is much more convenient to back up data and transfer large-capacity files to other computers. Moreover, under the same capacity, mobile hard disks are much cheaper.

What's the use of solid-state hard disks?

Compared with the ordinary hard disk, the solid-state hard disk has the following advantages:

1. It is fast to start, and there is no process of motor accelerating rotation.

2. No magnetic head, fast random reading, minimal reading delay. According to related tests: under the same computer configuration, it takes only 18 seconds for the notebook equipped with solid-state hard disk to appear on the desktop, while it takes 31 seconds for the notebook equipped with traditional hard disk, which is almost half the difference.

3. relatively fixed reading time. Because the addressing time is independent of the data storage location, disk fragmentation will not affect the reading time.

4. The writing speed of solid-state hard disk based on DRAM is extremely fast.

5. no noise. Because there is no mechanical motor and fan, the noise value is decibel when working. Some high-end or large-capacity products are equipped with fans, so noise will still be generated.

6. Low-capacity solid-state drives based on flash memory have low energy consumption and calorific value, but high-end or large-capacity products have high energy consumption.

7. There are no mechanical moving parts inside, so there will be no mechanical failure and no fear of collision, impact and vibration. In this way, normal use will not be affected even when the laptop is moving at high speed or even tilting, and the possibility of data loss can be minimized when the laptop accidentally falls or collides with hard objects.

8. the working temperature range is wider. A typical hard disk drive can only work in the range of 5 to 55 degrees Celsius. However, most SSDs can work at -1~7 degrees Celsius, and some industrial SSDs can also work at -4~85 degrees Celsius or even more.

9. The low-capacity SSD is smaller and lighter than the same capacity HDD. However, this advantage gradually weakens with the increase of capacity. Up to 256GB, SSD is still lighter than ordinary hard disk with the same capacity

What role does the hard disk in desktop play

Hard disk is an essential hardware for desktop computers, all-in-one computers and notebook computers.

About the hard disk:

The hard disk is one of the main storage media of the computer, which consists of one or more disks made of aluminum or glass. The disc is covered with ferromagnetic material. Hard disk includes solid-state hard disk (SSD disk, new hard disk), mechanical hard disk (HDD traditional hard disk) and hybrid hard disk (HHD, a new hard disk based on traditional mechanical hard disk).

Function of the hard disk:

It is the storage center of the computer, which is used to store all files of the computer (system, software, documents, movies, games, etc.). In a computer, the function of the hard disk is second only to CPU and memory.
