Lexar NM990 PRO 4TB PCIe 4.0 NVMe SSD

The Lexar NM990 PRO 4TB is a high-performance M.2 2280 NVMe SSD built on the PCIe Gen 4 x4 interface, leveraging a premium 3D TLC NAND architecture paired with an advanced DRAM-assisted controller to sustain peak sequential read speeds of approximately 7400 MB/s and sequential write speeds approaching 6500 MB/s. The drive employs a robust hardware-level NANDXtend ECC engine alongside SLC caching to maintain consistent performance under sustained mixed workloads, making it equally effective for large sequential transfers and intensive random I/O typical of professional production environments. A dedicated DRAM cache buffer ensures low-latency random access, targeting 4K random read performance in excess of 1,000,000 IOPS, placing the NM990 PRO firmly in the top tier of consumer-facing PCIe 4.0 drives while meeting the reliability expectations of professional and workstation-class deployments.

Designed for content creators, data engineers, and workstation operators handling massive file sets, the NM990 PRO at 4TB offers a substantial capacity footprint that reduces the need for secondary storage tiers in single-drive workflows. The drive's intelligent thermal management system integrates a dynamic thermal throttling algorithm that collaborates with the M.2 form factor's optional heatsink compatibility to sustain peak throughput during prolonged workloads such as 4K/8K video editing, 3D rendering batch jobs, and large dataset ingestion pipelines. Rated endurance is calibrated to the 4TB capacity class, providing a TBW figure appropriate for continuous professional use over an extended operational lifespan.

The NM990 PRO ships in the universally compatible M.2 2280 form factor, making it a straightforward upgrade path for systems with available PCIe 4.0 M.2 slots, including high-end consumer motherboards, professional workstations, and compact edge computing platforms. Its NVMe 1.4 protocol compliance ensures compatibility with modern operating system NVMe drivers and supports features including host memory buffer (HMB) fallback for enhanced queue depth management. The drive supports end-to-end data path protection, helping to guard against silent data corruption in mission-critical professional workflows where data integrity is non-negotiable.

Ideal for

• 4K and 8K non-linear video editing and post-production with sustained multi-stream read/write throughput exceeding traditional PCIe 3.0 storage
• High-resolution 3D rendering and animation pipeline scratch-disk storage requiring low-latency random I/O and high sequential throughput simultaneously
• Large-scale AI/ML dataset staging and preprocessing on local workstations before batch upload to network or cloud storage
• Rapid backup and restore operations for professional photographers and digital asset managers handling multi-terabyte RAW image libraries
• Workstation OS and application boot drive for compute-intensive scientific simulation environments demanding fast model load and checkpoint write speeds
• Edge computing node primary storage where a single high-capacity, high-throughput M.2 SSD must serve both OS and active working dataset within a constrained physical footprint
