The Lexar NM990 2TB M.2 2280 PCIe 5.0 NVMe SSD is a flagship storage drive designed for enthusiasts who require the absolute ceiling of modern data transfer speeds. While the 1TB model introduces users to the Gen 5 era, the 2TB variant hits the "sweet spot" of the lineup, offering significantly improved write speeds and double the endurance for heavy-duty professional workloads.
Built on the PCIe 5.0 x4 interface and utilizing the NVMe 2.0 protocol, the NM990 2TB is engineered to eliminate data bottlenecks in 8K video rendering, large-scale AI model training, and high-fidelity gaming.
Sequential Read: Up to 14,000 MB/s
Sequential Write: Up to 10,000 MB/s (a 33% increase over the 1TB model)
Random Read/Write: Up to 2,000K / 1,400K IOPS
Durability: Rated at 1,500 TBW (Total Bytes Written)
High-speed Gen 5 drives are notorious for heat, but the NM990 manages this through Thermal Defender Technology. It uses a sophisticated 8-channel controller paired with graphite heat-dissipation decals. This setup is designed to be 23% more power-efficient than standard designs, allowing it to maintain peak speeds longer before hitting thermal limits.
