Chinese PCIe 5.0 SSD tested with speeds up to 14.5 GB/s — Zhitai TiPro9000 sports 5th Gen YMTC 3D NAND and SMI SM2508 controller

YMTC SMI Silicon
Zhitai's TiPro9000 2TB SSD .

DIY.Zol.com.cn has reviewed a rather mysterious solid-state drive from Zhitai with a PCIe 5.0 x4 interface based on a controller with no markings and on YMTC's 5th Generation 3D NAND with the Xtacking 4.0 architecture. The SSD supports read speeds of up to 14.5 GB/s, enabling it to compete against the best SSDs. While the controller is not marked, this is Silicon Motion's SM2508, and SMI has confirmed this.

Zhitai's TiPro9000 2TB SSD carries a controller without markings, a 2GB LPDDR4X DRAM chip, and two 3D NAND packages. The 3D NAND packages reportedly integrate YMTC's 5th Generation 3D TLC NAND memory featuring the Xtacking 4.0 architecture, which suggests 128-layer or 232-layer devices and a very high interface transfer rate.
