The Lexar NM990 1TB M.2 2280 PCIe 5.0 NVMe SSD is a high-performance storage solution designed for the most demanding computing environments, including high-end gaming, 8K video editing, and AI development. Leveraging the massive bandwidth of the PCIe Gen 5 x4 interface, it effectively doubles the peak performance of previous-generation Gen 4 drives.
The standout feature of the NM990 is its sequential throughput. For the 1TB model, users can expect speeds that push the limits of modern motherboard chipsets:
Sequential Read: Up to 14,000 MB/s
Sequential Write: Up to 7,500 MB/s
Random Read/Write: Up to 1,600K / 1,000K IOPS
Endurance: rated at 750 TBW (Total Bytes Written)
Advanced Technologies
To maintain these extreme speeds without thermal throttling, Lexar utilizes Thermal Defender Technology. This system, combined with an integrated 8-channel controller and graphite heat dissipation decals, improves power efficiency by up to 23% compared to standard drives.
Intelligent Caching: Features an SLC Dynamic Cache that improves system responsiveness during sustained workloads, ensuring that the "snappiness" of the OS remains intact even during heavy data transfers.
DirectStorage Support: It is fully compatible with Microsoft DirectStorage, a technology that allows the GPU to load game assets directly from the SSD, significantly reducing loading times in modern AAA titles.
Management Suite: The drive is compatible with the Lexar DiskMaster tool, allowing users to monitor drive health, perform firmware updates, and securely erase data.
