Lexar NQ780 2TB NVMe SSD

The Lexar NQ780 is a 2TB internal solid state drive built for consumers who need fast storage in a standard M.2 2280 form factor. It connects through a PCIe 4.0 x4 interface and uses 3D NAND flash memory. Sequential reads reach up to 7000 MBps while writes reach up to 5000 MBps, supporting demanding workloads and large game libraries.

Sustained performance with 8-channel controller

An 8-channel Gen 4 controller maintains high throughput during extended transfers rather than only in short bursts. Host Memory Buffer and SLC cache technologies reduce latency and keep speeds consistent when the drive is under continuous load. Intelligent power management adjusts consumption to match the workload, helping thermal behaviour during long sessions.

Single-sided design and management tool

The single-sided PCB fits tight laptop bays and desktop slots without clearance issues. Shock resistance is rated at 1500G and vibration resistance at 20G for physical durability. Lexar DiskMaster software provides firmware updates, secure erase functions and health monitoring to maintain reliability over the 1200 TBW endurance rating.

Questions about this item

How hot does the Lexar NQ780 2TB run during sustained workloads?

The drive is rated for an operating temperature range of 0 °C to 70 °C and uses intelligent power control to manage consumption under load, while its single-sided design helps airflow in tight chassis.

What slot and protocol does my motherboard need for this LNQ780X002T-RNNNU to function?

It requires an M.2 2280 slot wired for PCI-Express 4.0 x4 with NVMe support; the drive is single-sided and draws power directly from the slot.

Will this 2TB NQ780 work reliably alongside an older PCIe 3.0 M.2 drive in the same system?

Yes — it will negotiate down to PCIe 3.0 speeds on a 3.0 slot, and its 1 500 000-hour MTBF plus 1200 TBW endurance rating remain unchanged regardless of the link generation.
