Lexar NM610 Prochat_bubble_outlineFrom real comments

Performance degrades over time, especially with games installed. Multiple commenters describe the drive performing well for the first weeks but then noticeably slowing down, particularly when used for AAA game storage. One user directly compared it to other SSDs in the same system that stayed fast while the NM610 Pro degraded. Reformatting offered only temporary relief before slowness returned within days, and root causes pointed to QLC NAND with a capped SLC cache and inconsistent random reads.

Reliability and endurance concerns worry some buyers. One user's drive stopped being recognized in BIOS after just four months of light use, and a warranty claim was rejected despite the failure. Another reported the 2TB Pro model's health already dropped 1 percent after only 3.75TB of writes, unfavorably compared to an older non-Pro NM610 that reached 50TB written at 97 percent health, raising doubts about the Pro's long-term durability.

Benchmarks look fine, but real-world use can feel sluggish. Despite advertised sequential speeds around 1050 MB/s still showing in benchmark software, users report slow folder browsing and file opening that doesn't match those numbers. This gap between synthetic benchmarks and daily responsiveness, combined with QLC-related cache limitations, left some feeling misled about real-world performance for tasks like gaming or file access.
