Description

The Lexar NM990 4TB M.2 2280 PCIe Gen5 NVMe SSD is designed for users who need extremely fast storage and high capacity in a compact format. With sequential read speeds of up to 14,000MB/s and sequential write speeds of up to 11,000MB/s, it provides the performance needed for demanding gaming, professional applications, large file transfers and content creation.

Its PCIe 5.0 x4 interface and NVMe 2.0 support take advantage of modern high-speed platforms, while the integrated DRAM cache helps maintain strong performance during intensive workloads. The 4TB capacity also provides plenty of space for large game libraries, high-resolution video projects, RAW photography, applications and other data-intensive files.

Features

High-Speed PCIe Gen5 NVMe Storage
Built around the PCIe 5.0 x4 interface, the Lexar NM990 is engineered for rapid data transfers and responsive system performance. Read speeds of up to 14,000MB/s and write speeds of up to 11,000MB/s can significantly reduce application loading times and speed up transfers of large files.

This makes the SSD particularly well suited to high-performance desktops, gaming PCs and professional workstations that support PCIe Gen5 storage.

Key technical details include:

• 4TB storage capacity
• PCIe 5.0 x4 interface
• NVMe 2.0 support
• Sequential read speed of up to 14,000MB/s
• Sequential write speed of up to 11,000MB/s
• 3,000 TBW endurance rating
• M.2 2280 form factor
• Integrated DRAM cache
• Microsoft DirectStorage support
• Backward compatibility with PCIe 4.0 systems
• Compatible with Lexar DiskMaster SSD management software

4TB Capacity for Demanding Applications
With 4TB of storage, the NM990 provides substantial room for modern games, professional applications, video footage, photographs and large project files. Users can store more data on a single drive while benefiting from fast access speeds and responsive performance.

For content creators, the high capacity is useful for working with large video files, RAW images and other demanding media. Gamers can also keep extensive game libraries installed without constantly moving titles between drives.

Built for Intensive Workloads
The integrated DRAM cache is designed to help maintain sustained performance during demanding read and write operations. Combined with NVMe 2.0 technology, the drive is built to provide efficient data handling and responsive operation during intensive workloads.

Whether transferring large project files, editing high-resolution media or running demanding applications, the NM990 is designed to keep storage performance moving at a high level.

Optimised for Modern Gaming
Microsoft DirectStorage support allows compatible games to take advantage of faster storage access, helping supported Windows systems load game assets more efficiently. When paired with compatible hardware and software, the PCIe Gen5 performance can contribute to shorter loading times and a more responsive gaming experience.

Compact M.2 2280 Design
The M.2 2280 form factor provides a compact storage solution for compatible desktop PCs and other systems with an appropriate M.2 PCIe slot. PCIe 4.0 backward compatibility also allows the drive to operate in supported PCIe 4.0 systems, although maximum performance depends on the host platform.

Lexar NM990 4TB SSD Part Number
This 4TB PCIe Gen5 NVMe SSD is supplied under part number / SKU LNM990X004T-RNNNG, making it suitable for identifying the specific drive when ordering, installing or upgrading a compatible system.

Performance and Capacity at a Glance
The Lexar NM990 combines a large 4TB capacity with next-generation PCIe 5.0 storage performance. Its high sequential transfer speeds, DRAM cache, NVMe 2.0 support and DirectStorage compatibility make it a strong choice for gaming PCs, professional workstations and demanding content creation systems.
