An SSD from Chinese manufacturer Zhitai has demonstrated impressive performance metrics, reaching sequential read speeds of up to 14.5 GB/s. Under the hood, the TiPro9000 2 TB SSD combines domestic YMTC 5th Generation 3D TLC NAND technology with Silicon Motion's SM2508 controller. The drive's architecture features a 2 GB LPDDR4X DRAM chip and two 3D TLC NAND dies utilizing 232-layer YMTC's Xtacking 4.0 architecture. While initial testing revealed peak sequential read and write speeds of 14,527 MB/s and 13,869 MB/s respectively, these rates are sustained through the SLC cache for approximately 24 seconds. Performance testing showed distinct operational phases. After the initial burst speed period, transfer rates stabilize at around 4,000 MB/s for 325 seconds before dropping to 1,700-1,800 MB/s. The drive then demonstrates recovery capabilities, returning to 4,000 MB/s after 259 seconds.

Random performance specifications are equally impressive, with the manufacturer claiming up to 2 million IOPS for reads and 1.6 million IOPS for writes. The TiPro9000's performance metrics position it competitively among top-tier PCIe 5.0 x4 drives. This shows the capabilities of Chinese-manufactured YMTC NAND memory technology paired with Silicon Motion's controller expertise, putting a lot of faith in China-made NAND Flash. With growing needs for AI and big data applications, performant storage systems are becoming key to many systems. However, Chinese companies still need a solid (pun intended) controller to compete with Western technology to complete storage manufacturing. Alibaba is working on a RISC-V-based controller, while InnoGrit has also been sampling controllers. We have yet to see commercial applications based on these two.
