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 w...
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...
All users may be familiar with the term “memory", because all electronic products must use memory, and usually more than one kind of memory. However, many people are confused about their types, specifications and forms, such as NAND Flash with high price, DRAM mentioned in industrial news, SRAM, SDRAM, DDR 3, DDR 4 and NOR Flash. What are these?
Memory is used to store programs and data. There are many kinds of memory, which can be divided into main memory and assistant memory according to their uses. In terms of memory hierarchy, there are register, cache memory, main memory and assistant memory. Different types of memory will be used in various application scenarios. In addition, this article will give some advises for how to properly d...
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!
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 e...
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.

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...
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 t...
