Why do SSD drives only have thousands of writes?

The actual number of writes of an ordinary home hard disk is worse than that of an SSD.

If there are only two states, and up to 50% of the stored electrons change, the data will be wrong; And if there are four states, up to 25% of the stored electrons change, and the data will go wrong.

At present, the flash memory used in SSDs is mainly NAND.

Because this thing is very precious, you have to pay attention to it every time.

Because there are only so many times in this field.

Because this is specifically designed to do just that.

Because this is a transformation according to the setting.

It's just a set state.

There's a reason for that.

How to replace customers who will not be bad?

At present, the mainstream 25nm process flash memory particles have fallen to less than 5000 times

Generally, there is no upper limit to the number of hard disk writes, and its life is the life of the internal optical disk, whether it is a mechanical disk or an SSD. The lifespan of a hard disk drive is calculated in hours. Typically 500,000 hours.

The lifetime of an SSD is calculated by the number of writes, regardless of the number of writes. The larger the capacity, the longer the lifespan of the SSD.

SSDs use NAND flash memory as the storage medium, so there will be a write time cap. The full write is called PE, and the lifetime of flash memory is measured in PE, and the life of a 34nm flash memory chip is about 5000 times that of PE, and the life of a 25nm flash memory chip is about 3000 times that of PE.

With the improvement of SSD firmware algorithms, the new SSD can provide fewer unnecessary writes. A 120G SSD can only be used as a pee when writing to a 120G file.

Summary. Kiss! Hello, this sentence may refer to the expected lifespan of SSDs, in general, modern SSDs have a lifespan of well more than 7000 reads and writes, and more than 250 hours of use.

Generally, the lifespan of an SSD is measured in terms of its total bytes (TBW), which indicates how much data can be written over the life of the drive. In general, modern SSDs have very high TBW values, often reaching hundreds of terabytes or more, so most users don't have to worry about longevity.

The SSD reads and writes 7,000 times in 250 hours.

Kiss! Hello, this sentence may refer to the expected life of the SSD, generally speaking, the lifespan of modern SSDs such as Xiaoqiao is far more than 7000 read and write operations, and more than 250 small liters of use time when disassembled. Typically, the lifespan of an SSD is measured in terms of its total bytes (TBW), which indicates how much data can be written over the lifetime of the drive.

In general, modern SSDs have very high TBW values, often reaching hundreds of terabytes or more, so most users don't have to worry about longevity.

Does such a second-hand notebook indicate that it has been mined?

Kiss! Hello! The Samsung MZVLQ512HBLU-00B00 is a high-performance NVMe SSD with a capacity of 512GB.

It uses a PCIe Gen3 x4 interface, which has very fast read and write speeds and response speeds. According to Samsung's official data, the SSD has sequential read and write speeds of up to 3500MB s and 3000MB s, and random read and write speeds are also very fast, at 500K IOPS and 480K IOPS, respectively. The SSD also features features such as core TRIM support, AES 256-bit encryption, and self-protection to meet the needs of users who are not in a bad mood.

Kiss! Yes. The configuration is R7 5800H 3060

Said to be running ASD SSD

Kiss! Hello, the R7 5800H is an AMD Ryzen mobile processor with 8 cores and 16 threads, and the clock speed is up to. This processor offers excellent multi-threaded performance and efficient energy management, making it ideal for high-performance laptops.

The 3060 may refer to the NVIDIA GeForce RTX 3060 graphics card, which is a mid-to-high-end graphics card with powerful graphics processing power. It supports ray tracing technology and DLSS acceleration, and the muffled circle can provide a smooth gaming experience and a higher quality of filial piety graphics. This card can also be used for GPU-accelerated tasks and deep learning applications.

Depending on the type of flash memory chip (SLC, MLC), SSDs can read and write 1-100,000 times, and professional-grade SSDs can reach 1-100,000 times, and the shortest service life can also reach 5-10 years.

It should be noted that the number of writes of an SSD does not mean that the SSD will break after 10,000 uses, but that each storage unit in it has up to 1-100,000 write times.

Since there are many storage units in a flash memory chip, and the main controller chip of the SSD will automatically allocate data to different storage cells in order to share the life risk, the service life of the SSD can reach 5-10 years.

We did not find the model parameters for 60g.

This is 120g, followed by 85000 read and 55000 written. Far more than you expected.

400-800 a day, why do you use it? Generally 5000 times is good. You might as well buy a better HDD.

The write lifetime of the SLC is 100,000 cycles. It is 10 times that of MLC and 50 times that of TLC.

The number of writes on an SSD is a full write erase.

The principle starts with the structure of the SSD. It is composed of two parts: a control unit (main control chip) and a memory unit (flash memory chip). The problem that affects the write life lies in the flash memory device.

In the physical structure of a flash memory cell, an electric field is created with an oxide, electrons pass through the oxide and store a charge, a potential value is recorded, i.e. 1 bit of data is written, and the same event occurs in the opposite direction when the data is erased. The problem is that the more electrons pass through the oxide, the weaker the oxide film becomes, and eventually the electric field cannot prevent the free movement of the electrons, and the unit is damaged; Therefore, both writing and erasing will reduce the life of the oxide film, and the manufacturing process limits the thickness of the film, which is the life of its storage unit.

SSD Introduction:

The storage medium of SSDs is divided into flash memory (flash chip) and DRAM. The operating temperature range of its chips is very wide, and the commercial products are 0 70; Industrial Grade Products-40 85 . Because SSD technology is different from traditional hard disk technology, many new memory manufacturers have emerged.

The new generation of SSDs generally adopts SATA-2 interface, SATA-3 interface, SAS interface, MSATA interface, PCI-E interface, etc.

Writes affect lifespan, and SSDs are limited in how much they can write. Reads do not affect lifespan, unlimited reads.

Solid-state drives are different from traditional HDDs, which require the swing of the head and the rotation of the motor for reading and writing. The SSD uses electronic electronics, and only when operating the flash memory chip of the SSD, it will produce an effective write, and when it is read normally, it only induces the data in the flash memory chip, and does not carry out effective data operations on the flash memory chip, so it is not counted in the number of writes.

The short lifespan of SSDs is mainly due to the number of reads and writes on the storage medium. This is less frequent than a traditional hard drive. However, it is generally okay to use 3 years. Traditional hard disks are only about 3 years old because of structural problems.

Due to the metal fatigue of the mechanical mechanism, the traditional mechanical hard disk will have different degrees of noise in about 3 years. The longer seek times lead to longer read wait times.

The number of bad blocks of the SSD also increases with time, and the occurrence of bad blocks will lead to write failures, and the write and read speeds will be greatly reduced, but they will not suddenly be unable to write and read.

Basically, the principle of the solid-state drive and the principle design of the USB flash drive are the same, the memory chip plus the control chip. Therefore, there is also a limit on the number of writes, more than the number of writes, the memory chip may have problems, can not store data again, compared with the ordinary mechanical hard disk has a low probability of bad sector phenomenon, has a greater data security advantage.

Limited write life (flash-based). Flash memory typically has a write life of 10,000 to 100,000 times, and custom ones can reach 1 million to 5 million times, but some parts of the file system (such as file allocation tables) will still exceed this limit over the lifetime of a computer. The special file system or firmware can share the position of the write, so that the overall life of the SSD can reach more than 20 years.

Some! And the number of reads and writes in the solid state is not as much as that of the mechanical one! In layman's terms, it is:

The more the solid state is used, the slower it is read and written, and the storage particles have a certain lifespan! But solid-state is flash! The speed is more than ten times that of machinery!

The read and write life of machines is generally much higher than that of solid-state ones! It is the magnetic track and the rotation of the motor to store the data!

It doesn't necessarily break down quickly, it's just a reference parameter that indicates how long the SSD will last, and in actual use it may be much larger than that.

The number of reads and writes of an SSD is not calculated by the number of files you copy, for example, your SSD is 250G, and you only write 250G once!

And this maximum number of writes is also theoretical, and exceeding it is not necessarily 100% broken.

The number of writes of the SSD is the same as that of the lithium battery, and the full discharge and charging are one, but if only 20% of the electricity is used, you can only recharge it once, so you should understand it when you install this calculation, if you write 25g each time, it can only be counted once.

The problem of the number of writes on the SSD means that it is counted once for each full write, which means that if you are 64g, it will only be counted once when 64g is full.

In fact, you don't have to worry too much about this problem, mechanical hard disks basically don't talk about write life, there is no difference between read and write, and life is usually calculated by time. Ordinary civilian-grade hard disks are generally 5 hours a day for three years; Enterprise class is 7x24 hours with 3-5 years.

The write life of an SSD is usually based on the amount of writes, which is calculated by pe. A complete erase of flash memory is called 1 time pe, so the lifetime of flash memory is measured in p e.

For example, most SSDs are MLC, which can generally complete 3000 PE times, and each time the capacity of a disk is full, it is counted as PE. For example, a 512G hard disk, and a total of 512G writes are counted as PE. The vast majority of qualified SSDs can reach 3000 times.

In addition, some SSDs are SLC and can be more than 10,000 times Pe. The TLC is usually 1500 times of PE, but Samsung's TLC can also be measured up to 3000 times.

Based on 3000 PE, a 512G SSD can be used for more than 100 years if it writes 20G per day. The lifespan is actually quite good.

SSDs were used on iPads before SSDs became commonplace, and the cache part of HDDs in the past was actually SSDs, but they were small. SSDs don't exist, the bigger the faster, it's all the same. In fact, in addition to the faster boot speed, the human eye in other places can not feel the difference at all, and more should consider the cost performance and budget.

SSD SSD is composed of flash memory chipsets, and the specific functions of SSD SSDs, to put it bluntly, are to speed up computer storage, especially laptops. The storage capacity of SSD SSDs is relatively small, and it is expensive, so it is basically used as a system disk. To say that it is more economical and of good quality, at present, I see "Lanke 256GB solid state drive, 799 yuan."

**Now it is more affordable.

Hello dear, this is the reason why the memory is too small. When using the computer, if you find that the computer frequently reads and writes hard disks, the possible problem is that the memory capacity is too small. Virtual memory is also known as virtual memory.

All programs running on the computer need to be executed through memory, and if the program takes up a lot of memory, it will cause the memory to be exhausted. In order to solve this problem, the virtual socks memory technology was produced, that is, a part of the hard disk space was evenly distributed to be used as memory. When the memory is depleted, the computer will automatically call the hard disk to act as memory to relieve the strain on memory.
