Chinese PCIe 5.0 SSD Hits 14.5 GB/s with YMTC 3D NAND

A new PCIe 5.0 SSD from Zhitai, called the TiPro9000, has been tested, showing impressive read speeds of up to 14.5 GB/s. This high performance is thanks to YMTC's 5th Generation 3D NAND and a Silicon Motion SM2508 controller. Zhitai TiPro9000: A Closer Look The TiPro9000 2TB SSD utilizes an unmarked controller (confirmed to be the SMI SM2508), 2GB of LPDDR4X DRAM, and two 3D NAND packages. The 3D NAND uses YMTC's 5th Generation 3D TLC NAND with the Xtacking 4.0 architecture. Performance Benchmarks The Zhitai TiPro9000 achieved the following performance during testing: Sequential Read Speed: Up to 14,527 MB/s Sequential Write Speed: Up to 13,869 MB/s Random Read Speed: Up to 2M IOPS Random Write Speed: Up to 1.6M IOPS The maximum sequential speeds are sustained while the SLC cache is active (around 24 seconds). After the cache is exhausted, the speeds drop to 4,000 MB/s before eventually recovering to 1,700-1,800 MB/s and then back up to 4,000 MB/s again. Overall The Zhitai TiPro9000 per…
