YMTC's PCIe 5.0 SSD debuts with 10,500 MB/s speeds to challenge global storage giants

Chinese memory manufacturer YMTC has unveiled its first PCIe 5.0 SSD under its own brand. The YMTC PC550 promises high performance with read speeds reaching 10,500 MB/s, marking the company's latest push into the competitive storage market. The drive arrives as global memory shortages persist, prompting some Western OEMs to consider Chinese-made alternatives for their speed test and google drive needs.

The YMTC PC550 is built around the company's X4-9070 memory chips, part of its newest 3D TLC NAND with Xtacking 4.0 architecture. This design stacks 267 layers, a significant leap in density and efficiency. The SSD comes in three capacities: 512 GB, 1 TB, and 2 TB, with the largest model achieving maximum write speeds of 10,000 MB/s.

Available in M.2 2280 and M.2 2242 form factors, the drive supports NVMe 2.0 and uses a four-channel controller. Unlike many competitors, it skips a dedicated DRAM cache, instead relying on Host Memory Buffer (HMB) technology. Power consumption stays under 6 watts during active use, while endurance ratings vary by capacity: 300 TBW for 512 GB, 600 TBW for 1 TB, and 1,200 TBW for 2 TB.

While YMTC has not announced specific partnerships, reports suggest leading PC manufacturers are evaluating Chinese memory chips to address supply constraints. The PC550 could potentially enter European and U.S. markets if OEMs adopt it for their devices, providing a viable option for future speed test and google drive needs.

The YMTC PC550 enters a crowded market with competitive speeds and advanced NAND technology. Its success may depend on whether Western manufacturers turn to Chinese suppliers amid ongoing shortages. The drive's performance and efficiency could make it a viable option for future OEM contracts.
