The Zhitai TiPro9000 is a solid-state drive in the M.2 2280 form factor, launched in December 2024. It is available in capacities ranging from 2 TB to 4 TB. This page reports specifications for the 4 TB variant. With the rest of the system, the Zhitai TiPro9000 interfaces using a PCI-Express 5.0 x4 connection. The SSD controller is the SM2508 from Silicon Motion, a DRAM cache chip is available. Zhitai has installed 232-layer TLC NAND flash on the TiPro9000, the flash chips are made by YMTC. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are processed more quickly. The cache is sized at 700 GB, once it is full, writes complete at 7600 MB/s. Copying data out of the SLC cache (folding) completes at 2200 MB/s. Thanks to support for the fast PCI-Express 5.0 interface, performance is excellent. The TiPro9000 is rated for sequential read speeds of up to 14,500 MB/s and 13,800 MB/s write; random IOPS reach up to 2000K for reads and 1600K for writes.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Zhitai guarantees an endurance rating of 2400 TBW, a typical value for consumer SSDs.
