Is it easy to scrap an SSD when it is turned on for a long time?

It has nothing to do with long-term booting.

It doesn't have to do with the number of reads.

SSDs are also not afraid of vibrations, as opposed to HDDs.

SSDs are also not afraid of power outages.

It has an absolute relationship with the number of writes!

The number of writes is the fatal flaw of SSDs these days.

As far as ordinary SSDs are concerned, the theoretical number of erases is about 3000 times.

SSDs, on the other hand, have their own balanced write mechanism, which will write to each area of the solid state in a balanced manner.

For example, a 64G SSD can theoretically be used for 3-5 years if it is full and then deleted every day.

To sum up, there is no absolute relationship between the long boot time and the lifespan of an SSD.

The life of the SSD is indeed shorter than that of the HDD, but I believe that this problem can be overcome after the technology is advanced, and a large amount of information needs to be read when it is turned on.

It is not easy to scrap after a long time of booting, and the key to affecting the life of the SSD is to write! A large amount of data will be written to the SSD, but after formatting, it will be resurrected in place!

Young people, this is the *** of medicine, all medicines will have negative effects, don't worry, pay attention to rest, avoid spicy and greasy food during the period, keep your body and mind happy, communicate with normal people often, you will be fine, believe me.

It's not that easy, big brands of SSDs can be tossed with confidence, at least during the warranty period, there will be no problems, except for cloud storage, of course.

If there is no power for a long time, it will be scrapped, and electronic components need to be powered on for a long time.

Problems are easy to occur when there is no electricity.

Of course not, the quality is not that bad.

The advantages of SSDs over traditional HDDs are high performance, small size, and no noise. The solid-state drive has many similarities with the ordinary mechanical hard disk we apply in terms of principle structure, such as analog sectors, analog tracks, etc.

In the SSD, the core part is the controller, which is the core of the entire SSD, which includes many architectures, such as read-write algorithms, interface definitions, etc. The main impact on the life span is the number of reads and writes, and in the algorithm definition of SSDs, only one modification is considered a real read and write.

Explanation of the meaning of the above content:

A complete erase of the internal flash memory of the SSD is called 1 time PE, so the life of the flash memory is measured in PE. The lifetime of a 34nm flash memory chip is about 5000 times pe, while the lifetime of a 25nm chip is about 3000 times pe. With the improvement of SSD firmware algorithms, **SSDs can provide less unnecessary writes.

A specific example, a 120G SSD, you need to write a 120G file to do PE once. In normal use, even if 50G is written every day and PE is completed once every 2 days on average, then there will be 180 PE times a year.

Among the SSD flash memory types, SLI is the most high-end, with a PE lifetime of about 5000 times; MLC is currently the mainstream, with moderate performance and life, and the life of PE is about 3000 times; TLC, on the other hand, is relatively the cheapest, theoretically the worst in performance and lifetime, with a lifetime of more than 1000 times. 1000 pes is estimated to have a theoretical lifespan of several years.

The lifespan of an SSD is not measured by how many hours a day you use your computer, but by how much data is written to the drive each day. The lifespan of an ordinary SSD is generally around 3,000 times.

Not much. SSDs are flash memory, and there is a limit to the number of times any storage medium can be used. SSDs can be stored 5 million times and HDDs 1 billion times.

SSDs can be seen everywhere in ultrabooks and some more mainstream computers, SSDs not only bring a faster experience in normal use, but also have the advantages of zero noise, not afraid of vibration, low power consumption, etc., but there are also many consumers who are worried about the life of SSDs, so what is the life of SSDs? Do we need to worry?

In response to the SSD life problem that netizens are asking, I will introduce it to you in detail.

How long is the lifespan of an SSD.

First of all, let's take a look at the principle of the solid state drive: the solid state drive is basically similar to the hard disk we use in the ordinary machine, such as simulated sectors, simulated tracks, etc. Inside the SSD, the core part is the controller, which is the core of the entire SSD, which includes many architectures, such as read-write algorithms, interface definitions, etc.

The main impact on the life is the number of reads and writes, in the algorithm definition of the SSD, a modification is considered a real read and write, the SSD has a life calculation formula, as shown in the following figure:

Formula for calculating the life of an SSD.

Due to the problem that SSD flash memory has a limit on the number of erase and write, this is also where many people criticize its short lifespan, that is to say, SSD has a life limit, of course, any hardware product has this concept of life. A complete erase of the internal flash memory of the SSD is called 1 time PE, so the life of the flash memory is measured in PE. The lifetime of a 34nm flash memory chip is about 5000 times pe, while the lifetime of a 25nm chip is about 3000 times pe.

Does it seem like the lifespan is shorter? Theoretically, yes, yes, but with the improvement of SSD firmware algorithms, SSDs can provide less unnecessary writes. Another specific example, a 120G SSD, you need to write a 120G file to be counted as a PE.

Ordinary users boast of normal use, even if they write 50G a day and complete PE once in 2 days on average, then there will be 180 PE times a year. You can calculate how many years 3000 P e can be used, and estimate that there is a theoretical life of more than ten years.

After one year of use, the SSD is still intact.

For solid-state drives, users should be concerned about capacity and **, after all, SSDs are now only a few hundred g, and ** is more expensive than traditional hard disks, everyone should consider the capacity and **, life span, in fact, not worse than traditional hard disks.

Not much, most of the SSDs on the market at present have about 1000 to 3000 times of erase and write, and the use of the stove more than 500 times is equivalent to about a quarter of the use, which can make the number of times that the tomb is bent with Kai is still ideal.

1.Reduced performance: As the SSD's lifespan gradually wears out, the read and write speeds may decrease. Quiet read and write operations to files can become slower and have longer response times.

2.Data Loss or Corruption: When the SSD runs out of life, there may be data loss or corruption scenarios. This may be due to the unavailability or damage of the storage unit.

3.Write errors and false checks: When the SSD is nearing its end, write operations may cause errors and check failures. This can cause the file to fail to write or write the wrong data.

4.Stop working: In some extreme cases, the SSD may suddenly stop working, be unrecognized or accessible, or emit unusual sounds.

5.Show Lifetime Warning: Some SSD drivers or management tools may offer longevity** and warning features. When the SSD reaches a certain level of life, a warning message may be displayed to prompt the user to pay attention to backing up data or replacing the hard drive.

It is important to note that different brands and models of SSDs may have different end-of-life characteristics and performance. In addition, the specific usage and environmental factors of each drive can also have an impact on how it behaves at the end of its life. In order to avoid data loss and hard drive failure, it is recommended to back up important data regularly, and take appropriate measures in time when SSD life warnings or other abnormal phenomena occur, such as replacing the hard drive.

The lifespan of an SSD depends on the daily maintenance method, and if it is well protected, the hard drive life of seven or eight years is not a problem.

Common sense of maintaining hard drives:

1.Protected from shock.

Hard disks are very sophisticated storage devices, and when reading and writing operations, the head floats at a height of only a few microns on the surface of the platter. Even when not working, the head is in contact with the platter. When the hard disk is working, once a large vibration occurs, it is easy to cause the head to collide with the data area, resulting in damage to the data area of the platter or scratching the disk, and losing the file data stored in the hard disk. Therefore, do not move the computer or mobile hard disk when working or before the spindle motor is stopped after shutting down, so as to avoid the impact between the magnetic head and the platter and scratch the magnetic layer on the surface of the platter.

In addition, the installation and removal of the hard disk.

Care should also be taken during the process to prevent excessive shaking or violent collision with the chassis iron plate.

2.Do not power off reading and writing.

At present, the speed of the hard disk is mostly 7200 rpm, when reading and writing, the whole platter is in a high-speed rotation state, if the power is suddenly cut off, the head and the platter will rub violently, resulting in bad sectors or even damage to the hard disk. Therefore, when shutting down, be sure to pay attention to whether the hard disk indicator on the chassis panel is not flashing, that is, the hard disk can only be shut down according to the normal procedure after the hard disk has completed the read and write operation. When the hard disk indicator flashes, the power supply must not be cut off.

3.Take care to control the ambient temperature.

When using hard disks, you should pay attention to high temperature, moisture, and electromagnetic interference. When the hard disk is working, it will generate a certain amount of heat, and there is a heat dissipation problem in use. The temperature should be 20 25, too high or too low will make the crystal oscillator clock.

The main frequency has changed. Temperature can also cause hard disk circuit components to malfunction, and magnetic media can also cause recording errors due to thermal expansion effects; If the temperature is too low, moisture in the air will condense on the integrated circuit components, causing a short circuit. When the humidity is too high, a layer of water film may be adsorbed on the surface of the electronic components, oxidizing and corroding the electronic circuits, resulting in poor contact or even short circuits, and the magnetic force of the magnetic medium will change, resulting in data reading and writing errors.

If the humidity is too low, it is easy to accumulate a large amount of static charge generated by the rotation of the machine, which will burn out the CMOS circuit, absorb dust and damage the magnetic head and scratch the disk.

The humidity in the computer room should be 45 to 65%. Pay attention to keep the air dry or power up the system frequently, and rely on its own heat to evaporate the water vapor in the machine. In addition, try not to keep the hard disk close to strong magnetic fields, such as speakers, speakers, motors, radios, mobile phones, etc., so as not to damage the data recorded by the hard disk due to magnetization.

4.Prevent computer viruses from damaging the hard disk.

Hard disks are the key targets of computer virus attacks, and attention should be paid to using the latest anti-virus software to prevent viruses. And pay attention to the protection of important data and frequent backups.

If the Samsung 840 EVO 120GB SSD has been written to the Samsung 840 EVO 120GB SSD after 10 days of non-stop random data writing, the health of the SSD has also begun to decline. Because the software writes when it is full of data, it is erased and then written, so the cycle is exactly the P E value of the simulated SSD.

Judging from the 10-day test, the write speed of HD Tune did not decrease after each large batch of data writes, and the average speed was about 140MB s, so the performance was very stable from the results.

What does 110TB mean? As a simple example, let's say we want to write 20GB of data to the Samsung 840 EVO 120GB SSD every day, and the write amplification of the SSD is 2, then we actually write 40TB of data every day, and the cumulative amount of writes in a year is. If you take 110TB as a conversion, this amount of writes can be completed in a year.

In fact, we write about 10-20GB per day on average, and it is really not easy to write bad SSD.

So you have to have a hard drive for 3 years no problem.

SSDs look at the drop in write data.

Feel free to use it, as long as there is no dark disease, you can use it until you don't want it.
