Lexar NM990 | 4TB NVMe SSD | M.2 | Gen5 | 14,000MB/s Read | 12,000MB/s Write

The Lexar NM990 4TB NVMe SSD is a powerful and future-ready storage solution designed for high-end systems where speed, capacity, and reliability are key. With support for PCIe Gen5 ×4 (NVMe 2.0), this drive delivers impressive transfer speeds and is perfectly suited for demanding tasks such as 8K video editing, large data processing, professional gaming, and content creation.

With sequential read speeds of up to 14,000 MB/s and write speeds of up to 11,000 MB/s, the NM990 4TB offers tremendous performance gains over previous generations. Its exceptional bandwidth allows for lightning-fast file transfers, reduced load times, and enhanced system responsiveness across all workloads.

The drive features 3D TLC NAND memory combined with the Maxio MAP1806A controller, specifically optimized for PCIe 5.0 performance. This combination ensures consistent and stable data throughput even during long, intensive workloads. Instead of a traditional DRAM cache, the NM990 uses Host Memory Buffer (HMB) technology to manage memory efficiently and make smart use of system resources.

In random operations (IOPS), the NM990 4TB achieves up to 2,000,000 IOPS read and 1,500,000 IOPS write, providing exceptional responsiveness in multitasking, virtual machines, and small file handling where speed is essential.

In terms of endurance, the drive is exceptionally robust, offering a Total Bytes Written (TBW) rating of 3,000 TB, proving that it is built for long-term use without performance degradation. Its MTBF (Mean Time Between Failures) rating of 1.5 million hours further highlights its reliability for professional environments.

Physically, the NM990 follows the M.2 2280 standard with dimensions of 22 × 80 mm and a height of 2.45 mm. This compact design makes it compatible with most desktops and laptops supporting PCIe Gen5. For intensive use or confined cases, adequate cooling or airflow is recommended to maintain peak performance.

The Lexar NM990 also supports modern features such as TRIM and S.M.A.R.T., allowing the system to monitor drive health and sustain optimal performance over time. It works seamlessly with Windows and Linux without additional drivers and is optimized for energy-efficient and quiet operation.

In summary, the Lexar NM990 4TB combines cutting-edge storage technology with high capacity, impressive speed, and solid reliability. With its outstanding performance, intelligent controller design, and compact build, this SSD is the ideal choice for users seeking maximum storage power in a professional-grade system.
