Chinese NAND Flash maker Yangtze Memory Technologies Corp (YMTC) has introduced its first client M.2 NVMe PCIe 5.0 SSD, named the PC550. As many PC OEMs face challenges in acquiring storage solutions at reasonable prices, YMTC aims to assist with its inaugural PCIe 5.0 NVMe model. The M.2 2242 and 2280 modules feature a PCIe Gen 5 x4 link combined with the NVMe 2.0 protocol and YMTC's X4-9070 3D NAND, built on Xtacking 4.0. YMTC designed the PC550 with a four-channel architecture, which the company claims reduces power consumption and thermal output compared to the more common eight-channel designs. The lineup includes capacities of 512 GB, 1 TB, and 2 TB, with no pricing on the official website. Consumers can contact YMTC, or wait for distribution channels to start offering these SSDs.

YMTC rates the largest variant at up to 10,500 MB/s for sequential reads and up to 10,000 MB/s for sequential writes. These speeds surpass most Gen 4 drives but fall short of some Gen 5 offerings that reach nearly 15,000 MB/s, suggesting a less powerful SSD controller. Random performance scales with capacity. The 512 GB model is listed at up to 880,000 random read IOPS and 1,100,000 random write IOPS, with an endurance rating of 300 TBW. The 1 TB and 2 TB models achieve approximately 1,300,000 random IOPS for both read and write, with endurance ratings of 600 TBW and 1,200 TBW, respectively. Idle power consumption is quoted at under 3 milliwatts, and active consumption is under 6 watts, making these figures suitable for notebook use.
