When it comes to domestic SSDs, what will be everyone's first reaction?
Is it already possible to produce SSDs independently in China?
Is it really purely domestic?
Is the quality reliable?
Will it suddenly break down in a short time?
Which manufacturer is used for the main control chip, and which manufacturer is used for flash memory?
A few years ago, when I encountered this kind of problem, I would have been skeptical, after all, solid-state drives also involve chip technology, and the development of domestic chip technology has always been obscure. Among them, there are companies that are determined to develop their own products but end up in failure, and there are also companies that have been concentrating on research but have not been able to produce results, and of course, there are some unscrupulous companies that do OEM foreign products under the banner of domestic chips to earn huge subsidies, and there are very few companies that can make practical results.
It just so happens that the product of this round of evaluation is a domestic SATA solid state drive - Netac Yueying N600S 512GB. 
Subject to m2 NV SSD** The impact of continuous decline, SATA SSD is now in a very bad situation, 512GB NV SSD is moving towards the standard of 140 yuan, and SATA SSD because of its manufacturing cost can not continue to compress the resulting many solid-state manufacturers in the last 2 to 3 years have given up SATA SSD to do NV SSD (including Langke is also actively in the field of NV SSD). 
I've always compared SATA SSDs to Derek Ross in the NBA. Because the emergence of SATA SSD is eye-catching, but its peak is extremely short, and it has been read faster, smaller and easier to install in a few years2. The SSD is pulled down.
When m2. When the ** of the SSD drops again and again, the living space of SATA SSD is greatly compressed. Nowadays, there are fewer and fewer manufacturers who insist on making SATA solid state drives, and its main sales target is old users who want to replace hard disks or upgrade old computers. It's unlikely that new users will ever consider getting a SATA SSD when it's time to configure a computer.
So is it true that SATA SSDs don't have a little bit of value?
Not really! Although SATA SSDs are obviously not as good as M. in terms of read speed and comprehensive cost performance2 SSDs, but SATA SSDs have one last advantage on the surface, which is the lower price point. For consumers who are on a tight budget but want to get the most out of their money, SATA SSDs offer a good trade-off. The read speed is much faster than that of an HDD, and the terminal ** is better than that of M2 SSD is a little lower, SATA SSD just stuck at this point. In addition, SATA SSDs are also a very good choice for users with limited motherboard expansion capabilities. In the process of this round of genuine evaluation, I will verify the "performance parameters" that the manufacturer has put on this SSD one by one, to see if it can reach the height advertised by the manufacturer, how fast and slow its reading speed is, how stable it is, whether its comprehensive quality is high or low, and whether it has the value to start, etc.
Hello everyone, I'm Natsume Talking about hardware, a digital home appliance product enthusiast and shovel officer, and I have been committed to doing real tests and sharing with you the interesting things I encountered during the evaluation process.
I have always insisted on the real machine evaluation, refused the cloud evaluation, only believed in my actual use experience and the real performance of the product, did not be a data party, and opposed the data theory, never carried articles on other platforms and plagiarized the remarks of other bloggers, I always believe that only in-depth use, and long-term use of a product can provide you with more real and useful reference information. First, Netac Yueying N600S 512GB - product features
Storage control chips
The storage controller chip is the core of the solid state drive, it is related to the stability and reliability of the solid state drive, and consumers who are familiar with the solid state drive will always pay special attention to the model or manufacturer of the storage control chip, because the storage control chip is indeed a prerequisite for high quality.
About this Langke Yueying N600S its memory control chip I also did a little investigation, according to the official disclosure of the information of Langke Yueying N600S memory control chip from the well-known domestic memory control chip design company Deyi Microelectronics Co., Ltd. *** The specific model of the memory control chip is YS9083XT, Langke Yueying N600S The whole process of independent research and development design, firmware development, production and manufacturing, taking the first step in domestic substitution.
Technical strength is safe and reliable
The enhanced 2K code length LDPC intelligent error correction algorithm is used to significantly improve reliability and durability. Deyi Microelectronics' exquisite technological innovation, professional technical support, and one-stop real-time service have created a more reliable storage system.
trim and wear balance
Support TRIM command to fully optimize the GC (garbage**) process of the SSD, so that the SSD can be in a more working state for a long time. The unique wear-balancing technology of the Lonco SSD makes the granular PE (Erase Write) loss more even, thereby extending the overall life of the SSD.

Considering that it is only a SATA SSD, we don't have to do too complicated hardware information tests on it, just a simple test of its sequential read speed and latency (read access time).

3. Netac Shadow N600S 512GB — Gaming test
The main purpose of buying an SSD is definitely to play games! Although the SATA SSD does not have a read speed of M2 NV SSD, but the read speed of SATA SSD is definitely a flash for HDD.
In terms of game experience, I have prepared two games, the first is the very classic "CrossFire", and the second is the more fashionable "Genshin Impact".
Genshin Impact test
CrossFire test
Both games run very smoothly and actually I would say playing games with SATA SSDs and m2 NV SSD playing some basic online games is not much different in terms of loading speed, because the shortcoming of whether you can play games is not on the hard disk, but on other hardware, so the game experience is actually dispensable.
Fourth, Netac Yueying N600S 512GB - review summary
It may seem to many people that SATA SSDs are gradually on the verge of obsolescence, in MWhen the 2 NV SSD successfully achieves a read speed of more than 7000MB s, it is really difficult for the SATA SSD to attract the attention of gamers.
But after this round of testing, an interesting question suddenly occurred to me: mCan a 2 NV SSD really improve the smoothness of your computer and applications?
Estimating is hard, maybe m.2 NV SSDs have long hit the ceiling in terms of smoothness improvement. ......
During the whole evaluation process, the game did not encounter any problems that could affect the smoothness, and the Netac N600S 512GB is still very stable, and Lanco is also trustworthy as a big storage brand. February** Dynamic Incentive Program
