Lexar LNM-1090Pro 4TB M.2 NVMe internal SSD

SKU CH-QDR8-TEFX6

High-speed internal SSD with up to 14,000MB/s read and 13,000MB/s write over PCIe 5.0

  • Up to 14,000 MB/s sequential read for rapid data access
  • Up to 13,000 MB/s sequential write to accelerate large file transfers
  • PCIe 5.0 interface with 232-layer 3D TLC NAND for high throughput
  • 6 nm controller improves thermal management and power efficiency
  • 2,800 TBW endurance rating on the 4 TB capacity for long-term reliability

High-Speed PCIe 5.0 NVMe SSD

The Lexar LNM-1090Pro 4TB is an M.2 2280 internal drive built on a 232-layer 3D TLC NAND and a 6nm controller. Sequential speeds reach 14,000MB/s read and 13,000MB/s write, with random performance up to 2,100K IOPs read and 1,700K IOPs write. It supports Microsoft DirectStorage for faster game loads and includes DRAM and SLC caches for responsiveness.

Compatibility Check Before Ordering

Verify that your motherboard has an M.2 slot wired for PCIe 5.0 x4 to obtain the advertised throughput. The drive measures 80 x 22 x 3.8mm and fits the standard 2280 footprint. Operating temperature range is 0°C to 70°C; ensure your case airflow or motherboard heatsink can keep the controller within this window under sustained loads.

Suited For High-Performance Builds

This 4TB model suits enthusiasts and professionals who need maximum capacity with PCIe 5.0 speeds for large project files or extensive game libraries. The 2,800TBW endurance rating supports heavy write workloads. Builders whose platforms only offer PCIe 4.0 or 3.0 slots, or who require a lower-capacity drive for a boot-only configuration, should consider a different capacity or generation.

Questions about this item

Will this 4 TB drive fit in a standard M.2 2280 slot?

Yes, the drive uses the M.2 2280 form factor measuring 80 x 22 x 3.8 mm, which matches the standard slot length and width.

What sustained write endurance does the 4 TB model provide?

The 4 TB model is rated for 2800 TBW, meaning it can accept 2800 terabytes of written data over its warranted life.

Does the drive need a heatsink for a PCIe 5.0 motherboard?

The 6 nm controller is designed for improved heat control, but many PCIe 5.0 boards include a dedicated M.2 heatsink; check your motherboard manual to confirm if one is required.
