How to choose a proper memory card?
2019-05-07

Memory cards can be divided into CF cards, MMC cards, SD cards, memory sticks and so on. At present, there are several mainstream memory card identifications such as Class and UHS. UHS product is better than Class products but its price is also higher than the latter. In addition, many factors will contribute to various performances even in similar product serious. It is recommended that friends who are ready to buy memory cards choose famous brand products in order to avoid losing important data.

We can trust the quality of QLC SSD?
2019-05-05

QLC SSD is the latest product to meet the demands of high capacity and low cost. It is the developing trend of SSD industry, although people have doubts and distrusts on it, it will prove its performance at the end. Finally the new technology will replace the old one, as if we take time to wait and test. It is the good sign of NAND flash market, no matter SSD or Micro SD Card; they will have more new solutions in future.

A clear introduction to definition and difference between DRAM and NAND Flash (1)
2019-05-19

There's a lot of information about memory on the Internet, because all electronic products must use memory. However, there are several kinds of memory. What can we do to distinguish among them? This is a great article that clearly talks about their definitions and difference in detail. Hope you can learn a lot from it!

Test practice and experience of distributed storage products(end)
2019-04-29

The entire development of distributed storage products can be divided into two phases. Test roles have different work in different product phase. This passage introduce the daily work of test engineers in detail, for example, designing and developing test cases. Of course, a good distributed storage product depends on cooperation of responsible test engineers, development engineers and operation engineers. If every link is done well, there will be good quality.

Test practice and experience of distributed storage products (1)
2019-04-28

How do we test a distributed storage product? How many members need to work together before releasing a good distributed storage product. This article is written by an experienced test engineers to introduce change of test roles and problems in test practice. Let us read it carefully and learn something from it.

How to choose the Best Flash Array: a Guide to SSD hard disk purchase
2019-04-11

With the gradual entry of flash products into data centers and the further increase of the utilization rate of flash memory, how to choose the best flash array becomes a major problem for users when they purchase enterprise-class flash memory and solid-state hard disk. This article not only discusses the common types of flash, full flash array and server-side flash, but also looks at each use case. It also describes in detail the decision points of flash purchase and the factors that should be taken into account when purchasing, so as to make investment more wise and efficient. Let's wait and see.

Understanding the master control and looking at the solid state drive(SSD): Initial understanding of the master control of the solid State drive
2019-04-13

The main function of hard disk is to store data. Flash memory plays the role of memory. And the master control is the direct controller of flash memory and a brain of hard disk. To understand the solid state drive, you must first be familiar with master control. With the continuous development of flash memory technology and the market of the solid state drive, master control has gradually become the core of competition in the hard disk market. How does master control work? Why is it so important for the solid state drive? Let's get to know.

Interesting argument of data center SSD
2019-03-31

According to Zhang Taile, vice president of products in Membalze, data center SSD refers to data center demand represented by Internet enterprises, and its typical application is characterized by distributed application, while traditional industries and enterprise users depend on centralized application. Focus and demands are different in various applications. Openness defeats closure! Zhang believes that NVMe SSD will be the mainstream in the future. Let’s wait and see.

Learn about every aspect of photoresist (3)
2019-03-30

This part introduces the evolution of photoresist from exposure source to film-forming material in detail. As time goes by, four types of photoresist have been developed by shrinking the line width of integrated circuits and continuously improving resolution, in order to meet various requirements.

Learn about every aspect of photoresist (1)
2019-03-18

Photoresist is an etching-resistant film material whose solubility changes through irradiation or radiation of different light sources. As the core of lithography, photoresist play an important role in micro-fabrication technology. However, it’s hard to make breakthrough of research and development in photoresist.

Price of DRAM falls again, setting a record in recent nine years.
2019-03-17

According to latest survey of DRAMeXchange, DRAM prices will continue to decline due to oversupply and weak demand. At present, most of market share of memory are mastered by three large companies, namely Samsung, SK Hynix and Micron. The speed of decreasing or increasing production is different, easy to cause legal problem of monopoly. Fortunately, it is generally believed that market conditions will recover with increasing demand in the second half of the year.

How to correctly select a micro SD card?
2019-03-13

Insert micro SD card to expand additional storage space is a good choice to satisfy storage needs. The article gives some good advice to us for how to correctly select a micro SD card. Speed levels, application performance, brand reputation and user testing are important factors to be considered when purchasing micro SD cards.

How to exploit IO performance of NAND Flash
2019-02-19

The passage mainly shows 3 kinds of concurrent execution units in NAND Flash chip, namely Device, Die, and Plane. By understanding internal structures and principles of these concurrent units, you may be will good at improving IO performance of NAND Flash.

Differences among DRAM, SDRAM, and SRAM
2019-2-6
The article mainly introduces differences among DRAM, SDRAM, and SRAM in detail. DRAM requires refreshing with large capacity, while SDRAM and SRAM not. In addition, the storage unit structure of them also be compared in the passage.
A brief introduction to the development of DDR memory
2019-01-14

The article briefly introduces the development of memory DDR. Memory can be divided into RAM and ROM according to whether data is lost or not at power failure. In addition, RAM can further be divided into SRAM and DRAM. The development of SDRAM is from 30pin SIPP interface to 30pin SIMM or 72pin SIMM. It also briefly show the characters and application of asynchronous DRAM which can be divided into FPM DRAM and EDO DRAM. From DDR to DDR4, the data transmission rate is increasing and capacity is becoming larger and larger.
