Since the fall of last year, China began to produce "national" 3D NAND flash memory. These are 64-layer chips from YMTC. Chinese developers of SSD controllers immediately became interested in this product. Chinese memory and Chinese controllers break the monopoly of foreign manufacturers of data storage systems, which is dictated by national security issues. Recently one of such products is presented.
According to the Internet resource , Jiangsu Huacun Electronic Technology (Jiangsu Hua Π‘un) has developed the HC6002 controller for client-grade SSDs for mainstream desktops and notebooks. Based on the new controller, a series of consumer SSD Phoenix MMSP350 M.2 NVMe has been developed with models with a capacity of 128, 256, 512 and 1000 GB.
The Phoenix MMSP350 SSD controller uses a PCIe 3.0 interface with support for the NVMe 1.3 protocol. Unfortunately, the company does not disclose the name of the supplier of flash memory chips. In the image above, the memory chips on the drives are marked with Jiangsu Hua Π‘un's own brand "MMY". Most likely, the manufacturer buys wafers with chips and cuts them into crystals and packs them himself.
But now we are talking about the controller. Phoenix MMSP350 SSDs using four PCIe 3.0 lanes are reported to achieve 2 GB/s sustained read speeds and 1,6 GB/s sustained write speeds. At a minimum, these data are confirmed by indications in the CrystalDiskMark test. As you can see, the Chinese are doing a good job at least with part of the task - with the development of controllers for SSDs. And the memory, even if now it is not local, will catch up with time. And that time is not far off. By the end of the YMTC year launch one of the most capacious 3D NAND in the industry with 128 layers.
