For recent time, the DIY market has constantly vibration, from the graphics card to memory, from the hard disk to the CPU, each product line has a large fluctuating in the price. From the "mining" from the summer vacation, the price of the graphics card is mad, and now the CPU in the CPU raised by the Intel's new eight-generation CPU is out of stock, and there is no one to get ordinary DIY users. Why do all hardware rises when they want to install? What is the price?
Of course, in addition to the DIY hardware prices triggered by these accidental factors, the price of solid state hard drives that have risen all the way in the third quarter of last year, and the price of the whole system stored in the memory product.
Especially when I saw a year ago, I just sold only 200 yuan of 8GB memory bar. Now I actually sell a high price of 800, 900 yuan, but also a DIY loyal enthusiast in the author, I can't help but sigh. "I know, I will have a memory number."
After a mad price increase, the storage product has no signs of price reduction. The reason is that the industry is in fact. No extrajure, flash particles are out of stock. So why does the short-selling of flash particles lead to a long-term price increase of storage products? What is the flash particles in the end? What contacts do you have to store products and flash particles? Below, the author will start from this storage product price increase, talk to everyone about flash particles.
Storage particles determine product cost
The so-called flash particles are generally referred to as flash memory. It is actually a non-volatile memory, that is, in the case of power outage, it can still be saved in the case, and is in units of fixed blocks instead of single bytes.
At the same time, flash memory is not like a RAM (Random Access Memory), so it cannot replace RAM; but in the process, whether it is flash particles, or memory DRAM particles, or mobile phone memory RAM particles, even It is the memory particles on the graphics card, which are both small and small, and after cutting through the wafer, the processing synthesis is performed on different assembly lines.
Go back to the flash, due to the flexibility of non-volatile (that is, the data can be stored after power off), and has the current storage product preferred storage feedstock.
The so-called "Solid State Hard Disk" name is also the characteristics stem from flash particles to be strong than the mechanical disk in the traditional machinery hard disk. It can be said that the emergence and great development of solid state drives, most of them must be attributed to the development and innovation of flash memory technology, so that most costs inside the solid state hard disk, or most of the cost inside storage products depends on the storage particles.
Status of technology and development of flash particles
Since the importance of flash particles in the contemporary for storage products, according to their internal electronic structures, there are mainly three, SLC (single-level storage unit), MLC (double storage unit), and TLC (three-layer storage unit), These three storage units have a significant difference in life and cost.
SLC (single-layer storage), single-layer electronic structure, the voltage change interval when writing data, the longest life, but cost is expensive, mostly used for enterprise high-end products.
MLC (multi-layered storage), the use of high and low voltage and the two-layer electronic structure constructed, the life is relatively long, the cost is acceptable, multi-purpose civil high-end products.
TLC (three-layer storage), is MLC flash extension, TLC reaches 3Bit / Cell. The storage density is the highest, and the capacity is 1.5 times the MLC. The lowest cost, the mission life is relatively low, the cost performance is high, and the mainstream manufacturer is preferred flashing particles.
In addition, some storage giants in recent years have been developed with QLC flash particles with a four-layer storage unit, a higher storage density. Of course, in addition to the research and development of storage capacity inside a single wafer on a plane, more mature, more aggressive R & D direction is actually in 3D stereo storage capacity, ie 3D NAND flash memory technology.
The 3D NAND flash technology is actually on the wafer arranged in the particle arrangement, and the superimposition of the particles is performed by technical means, i.e., the stack of multiple particles in the vertical direction is performed in a single crystal. The mass improvement of the storage capacity of the circle.
It can be briefly understood that 2D NAND technology is like building a bungalow on an empty floor, but the air area is limited, exceeding the total space area of the land, and the new bungalow cannot be built, and these bursts can be understood as storage space. Compared to 3D NAND technology is like the same air-building building, theoretically unlimited interior space, even if the air area is complete, it can also create new space by improving the height of the building.
Today, the flash industry, more mature and cost-effective technologies are still 64 layers 3D NAND technology. At the end of this year, the 72-story 3D NAND technology should achieve large breakthroughs, and even realize large-scale mass production, and even some leaders The 3D NAND granules that have been developed in the development of 96 and higher stacks.
Internal and external factor of storage products
After understanding considerable flash knowledge, we can return to your head and talk to storage products. Core reason, the raw materials represented by flash stock granules are out of stock, which is not single to flash, because memory and other products are actually the shortage of DARM particles, so as not to trigger controversy, in fact, the raw materials and processes of both of them are not large.
So why is the raw material such as flash stock particles? One chat here, many enthusiastic users will be boiling, and there is a matter of doing things. "It is definitely the manipulation of flash memory manufacturers such as Samsung, causing out of stock, price rising.
For this, the author does not publish any attitude, for the conspiracy theory, there will be some incidents, here the author just talks about personal opinion. Raw materials such as flash particles (including memory DARM particles), there are two mains, or two aspects. On the one hand, the other is the other.
The internal factor is that the wafer technology is not mature enough, and the good product is not high, causing the supply. Taking flash particle technology as an example, in the three-third quarter, the price of solid state hard disk is the most powerful time, Toshiba, Samsung and other major flash memory manufacturers are stepping up the development of 64-storey 3D NAND technology. Unfortunately, the results of research and development are not optimistic, good The rate is quite low;
Not only cannot be listed in accordance with the new solid products based on 64-storey 3D NAND technology, but the original 48-storey 3D NAND product line is also unable to continue reproduction of the 64-story 3D NAND product line, resulting in solid state hard drive products last year. The quarterly price has skyrocketed until the maturity of the 64-story 3D NAND product line is barely limit.
However, with the increase in demand, it comes to the third quarter of this year, the 64-story 3D NAN has not kept market demand, and the maturity of the 72-layer 3D NAND technology will determine the direction of the solid-state hard drive product.
The external reason is that the product line and other product lines have a high-capacity storage granules, as well as the high-cost capacity brought by the large profit margins of mobile phone manufacturers, so that the mainstream wafer manufacturers are more happy to provide raw materials and storage granules for new product lines such as mobile phones. The raw materials and storage particles that are allocated to traditional storage vendors have naturally result in the shortage of finished products, and the price is high.
I must return to normal after the skyrocket
Under the dual influence of internal or external causes, the crazy rise of storage products can also be understood. So, will this crazy rise continue?
The so-called "" Moon Ying is full of money loss, "any product will undergo peaks and troughs. The crazy price increase of this storage product is just a periodic fluctuation of the storage industry, as in the past, the price fluctuations in any storage industry, will be ushered in the return after madness.
There are also two, one is the arrival of the emerging industries such as mobile phones, the demand for welding particles, the decrease in the demand of the particles, the diploma of mobile phone manufacturers and profit margins, the main flash manufacturers' large-scale supplies will return Go to the traditional hardware storage market.
Second, technology research and development is always getting faster and faster, maturity and good quality will become higher and higher, and cost will be getting lower and lower; In summary, in the current storage product, it is necessary to have a DIY enthusiast, or an ordinary player should respond to normal mentality, especially friends with the downtime, should still be reasonably used according to their true needs. .
