Lexar NM760 1TB Review — Entry-Level PCIe 4.0 NVMe SSD
The Lexar NM760 1TB is an entry-level PCIe Gen4 NVMe SSD from Lexar, using the Silicon Motion SM2269XT controller and 3D TLC NAND for 5300 MB/s reads at a mainstream price.
Lexar positions the NM760 as its accessible entry into the PCIe 4.0 ecosystem, and the 1 TB capacity is where this drive becomes genuinely useful for most consumers. The Silicon Motion SM2269XT controller is a DRAM-less, power-efficient Gen4 x4 silicon designed for mainstream notebooks and budget desktop builds. The XT suffix explicitly denotes the DRAM-less design, which keeps costs down by relying on Host Memory Buffer (HMB) architecture instead of a dedicated DDR cache chip.
The SM2269XT delivers rated sequential reads of 5,300 MB/s and writes of 4,500 MB/s over an M.2 PCIe 4.0 x4 NVMe interface. These numbers are solidly mid-range within the Gen4 stack — faster than any PCIe 3.0 drive but well below the 7,000+ MB/s ceiling of flagship controllers like the Phison E18. For everyday desktop use and gaming, the difference between 5,300 and 7,000 MB/s is imperceptible: OS boot, application launches, and game loading all feel instantaneous.
At 1 TB, the NM760 offers enough space for a full OS installation, a substantial game library, and working files for content creation projects. The 3D TLC NAND is preferable to QLC for both sustained write performance and endurance — important considerations for a drive at this capacity where users will likely write more data over its lifetime. The DRAM-less HMB design is adequate for light to moderate use but will show increased latency under sustained mixed workloads compared to DRAM-equipped alternatives.
The 1 TB capacity also benefits from a larger SLC cache window than the 512 GB model, meaning sustained writes maintain peak speeds for longer before the cache exhausts. Against competitors, the NM760 1 TB sits alongside the TeamGroup MP33, Kingston NV2, and WD Blue SN580 in the value-oriented DRAM-less PCIe 4.0 segment.
✅ Storage Comparisons:
🚀 Performance and benchmarks
Sequential performance of 5,300 MB/s read and 4,500 MB/s write places the NM760 in the mid-range of the PCIe 4.0 stack. The Silicon Motion SM2269XT controller prioritizes power efficiency over maximum throughput, making it well-suited for laptop deployment where battery life is a consideration. In real-world use, the 1 TB capacity provides a larger SLC cache window than the 512 GB model, maintaining peak speeds during larger file transfers and sustained writes for a longer period.

- PNY XLR8 CS3140 1 TB: 7,500 MB/s read, 5,650 MB/s write
- PNY XLR8 CS3140 2 TB: 7,500 MB/s read, 6,850 MB/s write
- Asgard AN4 512 GB: 7,500 MB/s read, 5,500 MB/s write
- Asgard AN4 1 TB: 7,500 MB/s read, 5,500 MB/s write
- Lexar NM760 1 TB (this drive): 5,300 MB/s read, 4,500 MB/s write
The DRAM-less HMB design works well for everyday tasks — OS boot in under 15 seconds, responsive application launches, and fast game loading. Under sustained mixed workloads like video editing or heavy multitasking, the lack of dedicated DRAM manifests as increased latency. After SLC cache exhaustion, direct TLC write speeds typically fall to 400–800 MB/s for this class. Thermally, the SM2269XT is one of the cooler-running PCIe 4.0 controllers, making it a good fit for thin-and-light laptops with limited M.2 cooling capabilities.
🖥️ Endurance and warranty
Lexar provides warranty coverage on the NM760 consistent with its entry-level PCIe 4.0 positioning in the product lineup. Specific warranty duration and endurance figures for the 1 TB model are not widely published in Lexar public documentation. For comparable 1 TB TLC drives in this class, typical endurance ranges from 500 to 700 TBW with a three- to five-year warranty period. The 3D TLC NAND provides better endurance than QLC alternatives. For typical consumer use of 20–40 GB written per day, any reasonable endurance estimate would comfortably exceed the warranty period. MTBF is not separately published for this model.
