I’m having an issue with my NVMe SSD on a Lenovo LOQ 15IRX10 laptop.
The SSD benchmarks look normal in CrystalDiskMark (around 800–1800 MB/s read/write), and CrystalDiskInfo shows good health (95%) with temperatures between 47–70°C. Drivers and chipset are fully up to date, and there are no errors in Event Viewer or LatencyMon.
However, during gaming and video playback (except Cyberpunk 2077 and Forza Horizon 5), I experience frequent random stutters. At the same time, disk usage suddenly spikes to 100% for a split second, and response time jumps above 19,000 ms, then immediately returns to normal.
It feels like a latency spike issue rather than a performance or speed limitation. During these spikes, audio briefly cuts out and the entire system freezes for about a second.
I running windows 11 25H2 build 26200.7623 pro. SSD model shown in CrystalDiskInfo is: Netac N930E pro m.2 NVMe SSD 1TB Additionally, I tested the laptop using Fedora Linux, and the issue was exactly the same as in Windows. During video playback, the system experienced lag along with complete audio cutouts. The problem usually begins 2–3 minutes after powering on the laptop How can I accurately identify the root cause of this issue and properly fix it?
