Recently, SSD prices have been stable, and many SSDs have reached the 1GB 1GB area. Today, nearly 10 years after the birth of consumer-grade SSDs, we have finally seen the dawn of SSD adoption.

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. Compared with traditional HDDs, the biggest improvement of SSDs is to greatly increase continuous read and write speeds and random read/write speeds. How does this happen? 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 processes of mechanical hard disks rely on the operation of physical machinery. The read-write process of the SSD is under the command of the main control, and the flash chip is read and written through the transmission of electrical signals. Therefore, the SSD read and write process relies on electrical signals. The electrical signal is much faster than the physical machinery. This is the essential reason why the SSD hard disk reads and writes faster.
In the above principle, we all saw that, in addition to NAND flash memory particles, another key component that affects SSD performance is the SSD master control, which is equivalent to the SSD brain and controls the reading and writing of the entire SSD. Although there are a lot of domestically produced SSDs, as long as we dismantle them, we can regretfully find out that except for the outer plastic cases and PCB circuit boards, none of the two most important SSDs in the SSDs and 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 manufactured under the control of TSMC and other foundries. The master chip design also includes mature ARM cores, DDR physical layer and other IP authorizations, and R&D. The difficulty is greatly reduced, so this is also a place where chip development is easier to achieve. Nowadays, as countries pay 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 we have quickly entered the consumer sector. Today, we will evaluate the first consumer-grade product with domestic SSD master control, Lite-On T10PLUS, and see what its strength is. (If you want to learn more about the development of domestic SSD master control, please refer to the previous article published by PConline. "The domestic masters will use the "Chinese core" for the next generation of SSDs in spring.")
Product introductionAbout Jianxing Believe 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, while 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.
This time to evaluate the Lite-On T10PLUS, is the depth of cooperation between Lite-On and Yonex Technology. The product uses the main control STAR1000 from Recall Technology, which is the protagonist of this evaluation, the first consumer-grade domestic master control, and It also supports the high-speed SSD master control of the NVMe protocol.
Let's first look at Recall Core Technology. Recall Core Technology was established in early 2015 and its headquarters is in Beijing. 90% of R&D personnel have a master's degree or above. In 2016, the company successfully designed and used Taiwan Semiconductor Manufacturing Co.'s 28nm process to stream out enterprise-class SSD control chips. In November 2017, Yonex launched the first consumer-grade SSD master STAR1000 PCI-E master chip, supporting PCI-E 3.0 x4 channel and NVMe 1.2 protocol, supporting StarLDPC ECC engine, and supporting ASE256 and TCG OPAL encryption Can adapt to the existing MLC/TLC/3D MLC/3D TLC multiple flash types. In the process, the STAR1000 master used the TSMC 28nm HPC process, which is at the same level as the world's first-line products. Launched at the press conference was the Lite-On T10PLUS. Let us unveil today the mystery of the first consumer-grade SSD using a domestic master.
Product out of the box
Because this time we are getting products that have just been produced from the assembly line and have no fins attached, so the packaging of the Lite-On T10PLUS can only be used to claim the official website. 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. In addition, there are 256GB versions.
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 memories, each with a capacity of 128GB and a total capacity of 512GB.
We provide quick-turn injection molding by many types of materials, like ABS, PA66, PBT, TPU, TPE, PVC, PE, NYLON 6, PC, silicone, TPE, EPDM, PUR, etc. Special for some plastic parts. Our advantages in internal prototyping, bridge tooling and short-run manufacturing, which can eliminate the costly and time-consuming for customers a lot.
