Lexar NQ790 PCIe 4.0 NVMe SSD 4TB

The Lexar NQ790 is a high-capacity PCIe Gen 4 x4 NVMe SSD built on the M.2 2280 form factor, delivering sustained sequential read speeds up to 7,400 MB/s and sequential write speeds up to 6,500 MB/s. Leveraging a high-performance NVMe 1.4 controller paired with 3D NAND flash, the NQ790 4TB variant is purpose-built to serve workstations, creative production environments, and edge nodes where local storage density and throughput are primary concerns. The drive's architecture balances raw bandwidth with thermal efficiency, incorporating dynamic thermal throttling to maintain consistent performance during extended sequential workloads without the need for active cooling.

At 4TB capacity, the NQ790 addresses the growing demand for dense local NVMe storage in applications ranging from high-resolution media editing pipelines to AI inference caching at the edge. Its NVMe 1.4 command set supports improved power management states and host memory buffer (HMB) capabilities, reducing controller latency and improving random I/O responsiveness for mixed workloads. The drive targets environments where PCIe 5.0 headroom is not yet required but Gen 4 bandwidth remains essential for uninterrupted data throughput.

Launched in December 2025, the NQ790 4TB positions itself as a value-dense bulk storage solution within the Gen 4 ecosystem, enabling IT infrastructure teams to expand local workstation or edge node capacity without transitioning to a new platform. Its compatibility with standard M.2 2280 slots ensures drop-in deployment across a broad range of enterprise workstations, tower servers, and edge appliances, making it a straightforward capacity upgrade path for existing PCIe 4.0 infrastructure.
