About Lexar NM990

The Lexar NM990 4TB M.2 2280 PCIe 5.0 NVMe SSD represents the pinnacle of Lexar’s consumer storage lineup, combining massive capacity with the absolute limits of the PCIe 5.0 interface. While the lower capacities focus on speed, the 4TB model is the "powerhouse" choice for professionals handling massive datasets, high-resolution cinema raw files, and extensive game libraries without compromising on throughput.

At 4TB, this drive utilizes the full potential of its 8-channel controller and high-speed 3D TLC NAND. It is designed specifically for motherboards featuring the Intel Z790/Z890 or AMD X670/X870 chipsets that support native Gen 5 speeds.

Sequential Read: Up to 14,000 MB/s

Sequential Write: Up to 12,000 MB/s

Random Performance: Up to 2,000K IOPS read and 1,500K IOPS write.

Endurance: A massive 3,000 TBW (Total Bytes Written), making it suitable for constant write-heavy environments like server caching or scratch disks.

Thermal Management & Efficiency

Managing the heat of a 14GB/s drive is a challenge. The NM990 4TB employs Thermal Defender Technology, which uses an ultra-thin graphite heat spreader. This design ensures compatibility with tight spaces, such as high-end laptops or motherboards with integrated M.2 heatsinks, while maintaining 23% better power efficiency than standard Gen 5 competitors.
