Why do most computers cancel optical drives now?

One day, the new female colleague in the office pointed to the CD-ROM drive and asked me what it was for. I turned on the CD-ROM drive and told her that it was used to put tea cups. She was surprised and said that the design of the computer was really thoughtful.

I'm glad to answer your question. I am a quick repairman. If my answer is helpful to you, please leave me a comment or concern!

In the past, computers, whether laptops or desktops, were equipped with optical drives. Later, with the development of science and technology, the optical drive was gradually lost, so many computers canceled the optical drive. It is basically impossible to see the CD-ROM drive when buying a computer now. I think the possible reasons for the computer to cancel the optical drive are as follows:

(1) Reduce the weight of the fuselage.

Nowadays, computers are getting thinner and thinner, and the existence of optical drive greatly increases the weight of computers. So many computers don't have optical drives, and they are thinner. The computer is getting better and better, the weight is getting lighter and lighter, and the notebook has become much thinner, so there is not much space left for the CD-ROM drive. Therefore, the CD-ROM drive is cancelled to cater to people's aesthetics and make the space of notebooks and desktops more beautiful.

(2) The optical drive has been eliminated.

CD-ROM drive is mainly used to put CDs, but now CDs are no longer used in various occasions, and the storage capacity of CDs is limited, which can no longer meet the current storage needs. The disadvantages of CD storage led to the emergence of U disk, so CD was gradually not used by many people. Unused functions will be replaced, and the cancellation of the optical drive will leave more space for other components. So because of the progress of science and technology, the CD-ROM drive was cancelled, and a better U disk replaced the CD-ROM.

(3) USB flash drive with more convenient storage appears

The CD-ROM drive was killed because the USB flash drive installed the system. Otherwise, even if you have a 1t, 2T USB flash drive, it will be in vain. After the motherboard BIOS supports the CD-ROM drive, the floppy disk crashes. Therefore, there is always a key point to eliminate the things of the previous generation. For example, the 1349 bus that once appeared was much faster than the previous USB, but because of its poor background, the Apple family had to charge the motherboard manufacturer. So he died of greed. When the optical drive disappeared, the U disk had no advantage in capacity and price, so be careful. When installing software or operating system, the progress bar jumps up and the CD-ROM drive suddenly falters, and then the computer gets stuck. Coupled with the improvement of network storage, data storage is safer and faster. The CD-ROM drive finally failed.

Optical drives are gradually being phased out.

The function of the optical drive is to read the optical disc. As a storage medium, CD-ROM is cheap, but easy to be damaged, and its reading speed is slow and easy to be damaged, which has been gradually eliminated.

78 years ago, notebooks and desktops were generally equipped with CDs, which could be used to install operating systems and read CD data.

Now the operating system is basically installed on a USB flash drive.

With the price of U disk, SSD and HDD falling and the capacity increasing, the CD-ROM has little effect as a chicken rib accessory.

In the past, CD-ROM was the main input device for installing operating system and drivers. At that time, there was no small portable storage device like a USB flash drive that could start installing the operating system. Therefore, every computer technician in those days had a thick CD-ROM package, which contained various operating systems, drivers and CDs. The installation process is also very good, and the time is often one or two hours.

The only function of an optical drive is to read and write optical discs. Besides installing the operating system and drivers, you can also read CDs, VCDs, DVDs and even burn CDs. Although the CD is cheap, it is easy to be damaged and the reading speed is slow. Later, with the appearance of USB flash drive and the progress of technology, you can gradually start and install the operating system using USB flash drive. At that time, the main function of CD-ROM was for those who needed to burn CDs. For ordinary users, it may be used by the whole machine.

Now it is widely used, you can install the operating system and exchange data, and the reading speed of U disk is much faster, smaller and lighter, easier to carry, and the content is easy to rewrite, while CD is not easy to rewrite the content, even for most CDs, it is disposable. Coupled with the information demand of notebook computers, gradually all brands of notebook computers are not equipped with optical drives as standard, and optical drives are becoming more and more marginalized. Although some people may still need the CD-ROM drive, for most people, it is of no use except to increase expenses.

The reason is simple-low cost performance.

CD-ROM drive is a device for reading optical discs. There are few CDs now, so the CD-ROM drive is naturally cancelled by most computers.

There is a better substitute.

Under the influence of many people, the CD should carry many people's good memories. When I was a child, my family rented a lot of mobile Altman CDs.

Only with the development of technology, the prices of large-capacity portable devices such as U disk and mobile hard disk are getting cheaper and more popular, and the shortcomings of easy damage and slow reading and writing speed of optical disks are gradually exposed. Take the most common DVD as an example. The capacity of this CD will not exceed 20GB, and the reading and writing speed is only 20Mb/S, so it can't be used after a little scraping. Look at the flash drive again. Although the writing speed of USB 3.0 is 20M/s, the reading speed is very fast, almost reaching100m/s. Moreover, the capacity of U disk is much larger than that of optical disk, ranging from 16G to 256G. It is compact and easy to carry, so please be careful not to be hot-swapped or easily damaged.

In addition to USB flash drive, mobile hard disk is also a good choice. The mobile hard disk is smaller and has larger storage capacity.

The product characteristics of notebook lead to

Nowadays, many desktop hosts still retain the design of optical drive, and most of them have cancelled the optical drive.

The reason is that the notebook itself is relatively small, especially some thin ones, and the CD still takes up a lot of space and is not very beautiful visually. On the one hand, canceling the design of optical drive saves the space of the fuselage, on the other hand, it also reduces the weight of the fuselage, which is in line with the current actual situation.

In fact, CD-ROM drives, like floppy disks in earlier years, are a thing of the past. However, the CD has not been eliminated, and it is still a very important transmission medium in some units with strong confidentiality requirements. Moreover, as long as it is used properly, the life of CD-ROM is still very long, and some large enterprises will choose to use CD-ROM to store important information.

There are three reasons: occupying space, small capacity, slow speed and low frequency of use, and the optical drive can only be reduced to a niche application.

① The thickness of the notebook CD-ROM drive is 9.5mm, and the width and height of the desktop CD-ROM drive/recorder are 14.5*4.2cm, which takes up too much space. If the notebook wants to be light and thin, the battery will have to be increased if it wants to last for a long time, and the optical drive will inevitably be eliminated. Compared with USB flash drive, CD-ROM drive is inconvenient to carry.

② DVD has a capacity of 4.7GB, and double-layer 8.5GB. As the capacity of U disk reaches 8GB, optical storage has no advantage. /kloc-it usually takes 4 minutes to burn a DVD at 0/6 times the speed, and the transmission speed is only 24 MB/s.

Although the writing speed of most USB3.0 flash drives is less than 20MB/s, the reading speed exceeds 100 MB, and it can be accessed at any time, making it easy to carry. Fast fish eat slow fish, let USB flash drive beat floppy drive and CD-ROM drive. There is indeed a demand, and an external hard disk burner is a solution.

Coupled with the popularity of broadband, large-capacity transmission is mostly through the network, and then a wave of cloud storage, optical discs are less used for storage and download. Only in some confidential scenes, USB flash drive/network transmission is not allowed to use CD.

However, the life of optical storage is indeed longer. Sony recently introduced the third-generation "optical drive", which has a single box capacity of 5.5TB, reading and writing speeds of 375MB/s and 187.5MB/s/s, and the data can be saved for 100 years, but it is expensive, mainly for enterprise applications.

Hello, I'm Daming. In fact, the computer CD-ROM drive is just a product of an era, which will eventually be eliminated by the times. The elimination of computer optical drives is inevitable. Then Daming will talk about it in detail. Why is the computer CD-ROM eliminated? With the advent of the Internet era, the CD-ROM drive was cancelled.

In the early days, computers were equipped with optical drives. The main function of CD-ROM drive is to read CDs, which are mainly used to make "system disks" and "software tool disks". That is to say, early installation of systems and software requires optical drives. In those days, if the computer didn't even have an optical drive, the operating system couldn't be installed, and the optical drive was also an essential accessory.

With the advent of the internet age, the role of CD-ROM is not so great. Computer operating system and application software can be easily downloaded online, and people who want to watch movies, TV plays and listen to songs can download players online. If the media carriers in the past were newspapers and CDs, they will be eliminated with the advent of the Internet era.

The limitation of CD-ROM drive led to its cancellation.

Why are "CDs" limited? As we all know, the capacity of a "CD" is 700M, so it is difficult to store large-capacity files. You can still store the early win98.

But the operating system has developed to win 10 system, and the image file of WIN 10G is 4. 17G. The capacity of ordinary VCD discs is simply not enough. Even a DVD disc has a maximum capacity of about 10G, which is not enough for storing system files and application software.

For this problem, as long as a U disk or a mobile hard disk can solve the problem of insufficient CD capacity, "U disk" has become a new carrier for storing operating system files and software after "optical drive".

abstract

In short, the two main reasons for the cancellation of computer CD-ROM drive are "the rise of the network" and "its own limitations". Everyone can easily download what they need on the internet, using USB flash drive or mobile hard disk as the carrier, which is the product of the times!

To find out this problem mainly from the demand side, what is the CD-ROM drive for? It is a kind of reading medium for data transmission, which needs to be matched with optical disc, the ultimate device for storing data. Then, if something completely replaces the CD-ROM appears in the market, the mission of the CD-ROM drive will basically die.

There are three kinds of media that can replace CD. One is our common USB flash drive, and the other is mobile hard disk and Internet. First of all, the portability of U disk is very friendly, the smallest volume is only one twentieth of that of CD-ROM drive, and the capacity is dozens of times that of CD-ROM drive. Then, from the perspective of a single capacity, the price is much lower than that of an optical drive. It can be said that USB flash drive can do everything that CD can do. If it wants to be faster, it is a mobile hard disk, with larger capacity and cheaper single capacity. Let's talk about the internet now. It can be said that some common things that can be stored on CD can be downloaded from the Internet. Especially now, with the rapid development of optical broadband, every broadband is taking off at a speed of 100 megabytes.

We have to go back more than ten years. Why was the CD-ROM drive a must? At that time, many of us would buy a CD-ROM package, which contained all kinds of CDs we needed, because at that time, the capacity of U disk was really small, and the better one was 1 G, which was generally below 5 12MB. It is impossible to store a slightly larger file, let alone an operating system. However, at that time, the price of such a small-capacity USB flash drive was two or three hundred. The mobile hard disk is more expensive. Watch the CD. At that time, the price of a DVD was three to four yuan, and then the capacity could reach nearly 4 GB, and a lot of data could be burned at a time. This price was really good at that time. Buying a CD-ROM with recording is something to be proud of.

However, all this was replaced by later USB flash drives and high-speed Internet. There may be a demand for CDs in some specific occasions, so in the future technological development, CDs will inevitably be completely eliminated in the wave of technological development like floppy drives.

The CD-ROM drive is too old. With the technology of convenient storage, the optical drive has completed its mission and may be eliminated by history like a floppy disk.

Look at the storage devices at hand, such as USB flash drive and hard disk. The capacity of these storage devices is calculated by g, and you are embarrassed to say hello to others without exceeding 32 G! And these storage devices are very cheap, and you can definitely afford them.

In addition to USB flash drives and hard disks, there are many online platforms that are also free, such as Baidu network disk and QQ space, so you can upload photos with all your strength.

The size of an optical disc is usually several hundred megabytes, which requires a computer to have an optical drive. Long-term reading and writing of optical drives will wear out, and the price of optical drives is still a little expensive. In this case, the CD will not be used!
