Overview
The model LNM109P002T-RNNNU is the 2TB version of the Lexar Professional NM1090 PRO, a high-performance PCIe Gen5 NVMe M.2 2280 SSD optimized for gaming, content creation, AI workloads, and professional applications. Launched in April 2025, it offers an accessible entry into PCIe 5.0 storage with superior sequential speeds, efficient thermals, and DirectStorage compatibility for faster game asset streaming. It’s suitable for desktops, laptops, and PS5 expansions (with heatsink). Capacities include 1TB, 2TB, and 4TB, with the 2TB model retailing around $200–$225 as of late 2025.

DRAM
Yes, the 2TB Lexar NM1090 PRO features a dedicated DRAM cache, distinguishing it from DRAM-less Gen5 alternatives and ensuring consistent performance in demanding, mixed workloads. It includes 2GB LPDDR4x DRAM (sourced from Foresee), paired with SLC caching for optimized data mapping and reduced latency. This setup excels in sustained transfers, such as large file editing or multitasking, outperforming DRAM-less drives in random I/O by up to 50% in benchmarks.
Warranty
The SSD includes a 5-year limited warranty, protecting against manufacturing defects. Coverage ends at the earlier of 5 years or the 1,400 TBW endurance limit (roughly ~768 GB/day write over 5 years). Lexar offers worldwide RMA support through their site. As a 2025 product, early reliability is strong with minimal failure reports, though long-term data is still accumulating.
Performance
The 2TB model unlocks the full potential of the NM1090 PRO series, surpassing the 1TB variant’s write speed cap. It’s exceptional for sequential tasks like 8K video exports or AI dataset loading but ranks mid-tier among Gen5 peers (e.g., behind Crucial T705 or WD SN8100) in latency-sensitive gaming or productivity tests. The 6nm controller keeps it cool, with peak temps 36% lower than 12nm rivals.
Benchmark Highlights (2TB Model)
- Synthetic (CrystalDiskMark/ATTO): Sequential read/write ~13,800/12,900 MB/s; Random 4K read/write ~1.95M/1.75M IOPS (strong for Gen5, with DRAM aiding sustained runs).
- PCMark 10 Storage: Overall score ~8,500 (above average for daily use; trails elites by 10–15%).
- 3DMark Storage (Gaming): Score ~5,100 (good DirectStorage support; ~15% behind top Gen5 in load times).
- Blackmagic Disk Speed: Read ~11,200 MB/s; Write ~12,100 MB/s (top-tier for creators).
- AI/LLM Load Times: Competitive for mid-sized models (e.g., ~4.5s for 13B Llama); efficient power draw aids laptop use.
- GPU DirectStorage (GDSIO): Reads up to 7.2 GiB/s; writes stable at ~6 GiB/s.
It ramps to peaks rapidly but may sustain 80–90% under heavy loads without cooling. Compared to Gen4, it’s up to 200% faster in compatible scenarios.
Feedback from the Web
Released mid-2025, the 2TB model has garnered solid user buzz on platforms like Amazon (early 4.5/5 stars) and X, where it’s hailed for value during sales (e.g., $179–$224). X posts focus on deals and builds, with Japanese/Italian users praising speeds in reviews. Reddit threads are sparse but positive, often comparing it favorably to Gen4 Lexars. No major red flags; it’s seen as a “budget high-end” option.
Professional Reviews
- The SSD Review (2TB, 9/10): “SMI SM2508 with Micron B58R is a success—super efficient, low heat, and hits rated speeds consistently.” Loves value; notes double-sided design but minimal thermal issues.
- StorageReview (8.5/10): “Best balance for cost/performance in Gen5; DRAM shines in mixed workloads.” Recommends for creators; minor con: not the absolute fastest random IOPS.
- PCMag (3.5/5): “Fast sequentials, but mid-pack in PCMark/gaming traces—beats DRAM-less Gen5.” Good for throughput; suggests waiting for sales.
- TweakTown (92%): “Super fast and efficient; SM2508 keeps it cooler than Gen4 averages.” Highlights low power; ideal second drive.
- PCWorld (3.5/5): “Within reach of rivals in random tests; DRAM pays off.” Solid but not class-leading; on par pricing.
User/Community Feedback
- Reddit (r/pcmasterrace, r/buildapc): Users in build threads call it a “great Gen5 starter” for OS/gaming drives, noting stable temps in sessions. One compared to Lexar NM790 (Gen4): “Same quality, but future-proof speeds—worth 2TB over 1TB.” Isolated complaints on Lexar reliability (e.g., one 8TB failure), but none specific to NM1090 PRO.
- X/Twitter: Promo-heavy (e.g., Italian deals at €200, Japanese performance videos hitting 14GB/s reads). Users share hauls with Ryzen builds, emphasizing no throttling. One giveaway bundle with DDR5 drew excitement for gaming setups. Sentiment: “Affordable Gen5 win” for AI/gaming; low heat praised in laptops.
- Overall Sentiment: High marks for efficiency and bang-for-buck (beats pricier Gen5 in thermals). Drawbacks: Double-sided may need airflow; not peak for ultra-gaming. Perfect for upgrades without breaking the bank.
