Chinese companies are rapidly reducing their reliance on foreign semiconductor manufacturers. Reviews of the Zhitai TiPro9000, a Chinese solid-state drive (SSD), indicate performance on par with the best modern PCIe 5.0 x4 models.
The 2TB Zhitai TiPro9000 features a pair of fifth-generation YMTC 3D TLC NAND chips built on the Xtacking 4.0 architecture, supporting 128- and 232-layer configurations. It also incorporates a 2GB LPDDR4X cache chip and utilizes the Silicon Motion SM2508 controller.
Performance tests show sequential read speeds of 14,526.95 MB/s and sequential write speeds of 13,869.24 MB/s. These results are comparable to reference drives using the SM2508 controller. However, peak performance is only sustained for 24 seconds. After that, speeds drop to around 4000 MB/s, and then to 1800 MB/s after 5 minutes before rebounding to 4000 MB/s after an additional 4 minutes. Random read speeds reach 2.15 million IOPS, and random write speeds reach 1.83 million IOPS.
The manufacturer claims the Zhitai TiPro9000 offers not only high performance but also reliability, boasting a 1.5 million-hour mean time between failures (MTBF) and an endurance rating of 1200 TBW (terabytes written).
