Recently, the price of SSDs has been stable, and many SSDs have entered the field of 1 yuan and 1GB. Today, nearly 10 years after the birth of consumer-grade SSDs, we finally see the dawn of SSDs once again.
Regarding SSD, I believe that many DIY players know it well, but it is good where it is, and it may not be clear to many people. The biggest improvement of SSD compared to traditional HDD is that it greatly improves continuous read and write and random read and write speeds. How do we do it? Let's start with the working principle of SSD and HDD.
The reading and writing process of the mechanical hard disk requires the head to seek the position of the data storage on the disk under the precision cooperation of other mechanical parts. In other words, the reading and writing process of the mechanical hard disk relies on the operation of the physical machinery.
The SSD read/write process, under the command of the master, completes the reading and writing operations of the flash memory chip through the transmission of electrical signals. Therefore, the read/write process of the SSD depends on the electrical signal. The electrical signal is better than the physical machinery. The operation is much faster. This is the essential reason why the SSD hard disk reads and writes faster.
And we also saw in the above principle. Influencing SSD performance In addition to NAND flash memory particles, another key component is the SSD master control, which is equivalent to the brain of the SSD and controls the reading and writing of the entire SSD..
Although there are many domestically produced SSDs, as long as we dismantle them, we can regretfully find out that except for the outer plastic shells and PCB circuit boards, none of the two most important SSDs in the SSDs and the NAND flash memory are domestically manufactured. Fortunately, this situation is gradually changing.
Unlike SSDs, which have higher R&D thresholds for NAND flash memory, SSDs can be manufactured and delivered to TSMC and other foundries. The main control chip design also has a mature ARM core, and IP authorization such as DDR physical layer is available. The difficulty is greatly reduced, so this is also a place where chip development is easier to achieve.
Nowadays, as the country pays more and more attention to the research and development of chips, more and more funds are invested. We naturally have a fruitful result in the field of SSD control, and quickly entered the consumption field.
Today we will evaluate it The first consumer-grade product using domestic SSD hosting, Jianxing T10PLUS, to see how its strength.
Product introduction
About Jianxing believes that everyone is familiar with it. Lite-On is part of the Taiwan Lite-On Group and has a leading position in the optical storage market. At the same time, the company is also a well-known brand in the field of SSD production.
Although Jianxing is a Taiwanese company, he has long been rooted in the Mainland. In 2016, Lite-On established an R&D center in Guangzhou to contribute to the development of the domestic semiconductor industry.
The Lite-On T10PLUS to be evaluated this time is the product of the deep cooperation between Jianxing and Yoncore Technology. The product uses the master control from Yoncore Technology. STAR1000This is also the protagonist of this evaluation. The first consumer-grade domestic master, and still supports the NVMe protocol high-speed SSD master.
Let's start with Recalling Core Technology. Recalling Core Technology was established in early 2015. Our headquarters is located in Beijing. 90% of R&D personnel have a master's degree or above.
In 2016, the company successfully designed and used TSMC's 28nm process to stream out an enterprise-class SSD master chip. The progress was rapid. In November 2017, Yonex launched the first consumer-grade SSD master STAR1000 PCI-E master chip. Supports PCI-E 3.0 x4 channel and NVMe 1.2 protocol, supports StarLDPC ECC engine, supports ASE256 and TCG OPAL encryption, and can adapt to existing flash memory of MLC/TLC/3D MLC/3D TLC.
On the process, the STAR1000 controller used the TSMC 28nm HPC process, which was at the same level as the world's first-line products. The launch of the launch of the T10PLUS was a joint effort. Today, let us unveil the first consumer SSD using a domestic master. Mysterious Veil.
Product out of the box
Because this time we got a product that was just produced from the assembly line and was not affixed with heat sinks, so the packaging of the Lite-On T10PLUS can only be used to claim the official website's announcement.
It can be seen that the product uses a lot of Chinese elements, including the Chinese red color scheme, and the Chinese knot pattern, which all echo the Chinese core of the product's main selling point.
What we got this time is the 512GB Lite-On T10PLUS. There are 256GB versions of this product.
The Lite-On T10PLUS uses the STAR1000 master control from Recall Technology. You can watch the unicorn's LOGO. This is the LOGO of Recall Core Technology. I believe that more and more SSDs will have a little dominance in the future. Horned beast.
The front and back sides of the Lite-On T10PLUS are inlaid with two Toshiba original 64-layer 3D stack TLC flash memory, with a single capacity of 128GB and a total capacity of 512GB.
The cache uses South Asia's LPDDR3, model NT6CL128M32BM-H2, with a single capacity of 256MB, and a total of 512MB on both sides.
Continuous read and write and random read and write tests
The test uses the combination of the current top AMD home platform Ryzen 7 2700X with ASUS ROG C7H (WI-FI). The platform is very representative.
In order to see the performance of Jianxing T10PLUS more intuitively, we have added two opponents to it, namely, the big brother Jianxing T10 and the younger brother Jianxing T11.
The Jianxing T10 is an NVMe SSD that was launched at the beginning of 2017. Due to its excellent performance and relatively affordable price, the Lite-On T10 is one of the hottest NVMe SSDs in 2017.
The product uses PS5007-11 master from Taiwan Enterprise Group, uses 8-channel design, supports PCI-E 3.0 X4 mode, theoretical bandwidth can reach 32Gbps. The product uses the Toshiba original MLC flash memory particles, cache It is NT5CC128M16IP-DI cache from South Asia Technology, with a capacity of 512MB.
Group Connect PS5007-11 Master
Groups, Hui Rong and other Taiwanese masters are the most dominant brands in the market for mid- to low-end SSDs because they have a very high price/performance ratio. As the Lite-On T10PLUS is also priced at the mid-end, it can be said that the Taiwanese main control is The domestic SSD controls the first opponent to face.
The Lite-On T11 is the SSD launched by Lite-On in the second half of 2017. The product is mainly cost-effective, and it is also very popular with the market. The Jingdong evaluation has already reached 14,000. Therefore, comparing it with the SSD is quite comparable.
The product we got this time is the 256GB version, which uses Toshiba's 15nm TLC flash memory chips, and the cache uses Hynix's H5TC2G636FA 256MB DDR3L cache.
The main control uses the more cost-effective Grouplink PS5008 main control, dual-core four-channel main control, supports PCI-E 3.0 X 2 mode, theoretical bandwidth is only 16Gbps, is an out-of-the-box entry-level NVMe SSD.
We don't have much to say. Let's take a look at how they perform in the actual test.
Continuous read and write tests
When we read and write large files, the hard disk is tested for continuous read/write performance. At this time, hard disk drives with continuous read/write capability can complete large file transfers in less time.
Test summary: In terms of continuous read/write performance, the Lite-On T10 and Lite-On T10PLUS are basically at the same level. After all, these two SSDs are running PCI-E 3.0 X4 channels, and the theoretical bandwidth is twice that of the Lite-T11. A careful comparison is made. We can also find that the LiteX T11PLUS performs slightly better than the Jianxing T10 on pure theoretical write performance tests.
However, abnormal performance has also appeared, mainly in the HD Tune Pro test. In the HD Tune Pro test, we used up to 40GB of test files, easily crossed the threshold of the SLC cache, removed the acceleration effect of the product cache and measured the true performance of the product flash particles. However, this situation is extremely extreme, in everyday use. There are not many situations. After removing the cache bonus, the Lite-T10PLUS score is not ideal. It is worth mentioning that the Lite-On TT11 has the smallest cache among the three.
Random read and write performance test
In fact, in our daily use, more than 90% of operations are randomly reading and writing fragmented files. Therefore, the SSD's random read/write capability is the one that most affects the user experience, and the SSD's master control starts in random reading and writing of the SSD. It was a decisive role.
SSDs are relatively brainless when they are written continuously. At this time, the SSD master only needs to control the SSDs to write files. It also tests the stability of flash memory particles, but random read and write is not the same. The SSD must find the exact bits and pieces. File, and as fast as possible to read or write more fragmented files to the right place, this time is very test the SSD brain - SSD master control performance.
Test summary:
Although Lite-On T11 is not as good as Lite-On T10 in theoretical bandwidth, Lite-On T11 completed anti-killing of Lite-On T10 in a random-write performance test, which proves that the most tested method for random read/write capability is the master control algorithm. And performance, can clearly see that the new generation of Lite-On T11 group master write performance will be much better than the main control on the Lite-T10.
The most pleasant surprise is that the Lite-On T10PLUS can perform in most random read-write performance tests. We can proudly say that the performance of the domestic master control does not lag behind that of the same-level Taiwanese system master, and it is even better.
3 other tests and summary Software score Now many software can do a comprehensive assessment of SSD performance, let's look at their scores.
Test summary: Overall, the Lite-On T10PLUS and the Lite-On T10 have their merits in both running software. After all, each software has different standards for scoring and different performance weights.
Daily use and stability testing
For an SSD, the ordinary running points are not exactly equal to the daily experience. Let's take a look at the SSD's ability to handle various sizes of files.

Lite-On T11
ATTO Disk Benchmark is an easy-to-use disk transfer rate detection software that can be used to detect the read and write rates of hard disks, USB flash drives, memory cards and other removable disks. It can monitor storage devices for various sizes Fragmented file read and write speeds, such as 4KB results are read and written many 4KB size, a total of 256MB size folder speed.
In theory, the more fragmented files, the more fragmented, the slower the reading and writing speed of storage devices.
We can see that except for those files that were initially too cumbersome to read and read slowly, Lite-T10's performance in dealing with fragmented files of various sizes is relatively stable, and Lite-On T10PLUS is processing 16KB to 2MB files. It will be more efficient, but when the file size is larger than 2MB, the read and write performance will drop a lot. This shows that there is still room for improvement in the STAR1000 master..
The Lite-On T11 has a relatively low random read/write performance, but it is also relatively stable for reading and writing various types of files.

This is the detail of our SSD performance in the HD Tune Pro test. In the case of maintaining a higher average reading and writing speed as much as possible, The slower the read/write speed fluctuation curve, the more stable the read/write speed , From this point of view, Lite-read T10PLUS's read-write curve is relatively stable and stable.
Finally, let's take a look at the performance of the SSD's daily transfer files. This is the folder we use. It is about 15.5GB in size. In order not to make the read speed of the hard disk a bottleneck, we used the Samsung 970EVO 1TB as the original hard drive for the files. , Then copy to the target hard disk.

In practical applications, the initial writing speed of the Lite-On T10PLUS will be very fast, but it will drop to about 500MB/s later, while the Lite-T10's transmission speed has been very stable. The Lite-On T11 is also very fast at the beginning, but Later it will fall to 200MB/s, taking into account the bandwidth of the Lite-T11, which is also a relatively normal result.
In the continuous writing of large files will also compare the strength of SSD particles, the impact of this test particle will be relatively large, Jianxing T10 uses MLC flash memory, transmission is more stable and normal.
Evaluation summary
Regarding the performance of this product, the Lite-On T10PLUS, you must have seen it in the above tests. Its hard power is absolutely no problem, and random read and write performance is stronger , The domestic SSD master control did not fall into the wind in the contest with Taiwan's mature Taiwanese masters. Of course, it is not worth buying an average product value, but also need to look at its price.
In terms of price, except that Lite-On T10PLUS did not use the merchant price for Jingdong's self-operated products, we tried to use Jingdong's own real-time price as a comparison. The performance gap between different models of the same model will not be too large, but it is worth noting that Lite-On T10 The 256GB cache was half cut, only 256MB.
It can be seen that the Lite-Built T10 PLUS has the lowest price in the 256GB range. Considering the high performance of the Lite-On T10PLUS, the Lite-T10PLUS 256GB is not cheap, but it is clear that the Lite-T11 is the king of price/performance when the capacity is higher. .
It is undeniable that the domestic SSD master control is now not only entering the consumer market, but also the products with domestic SSD master control are still quite competitive in the market. This is a huge and worthy progress for the development of domestic chips. .
The domestic SSD control industry has blossomed. The next step is to look at domestic NAND flash memory. We hope that we can see purely domestic SSDs in the market in the future.
