What reviewers say

Lexar NM790

  • 4.9 / 54,300 ratings

Reviewers and owners rate the Lexar NM790 highly for its fast read speeds and compatibility with PS5 and PCs. Many praise its value, though some note that write speeds can slow during prolonged writes due to its DRAM-less design.

  • PS5 compatibilityPraisedMany mention it works perfectly in the PlayStation 5 for expanded storage.
  • ValuePraisedReviewers often say it offers great performance for the price.

Questions and answers

Which is better for gaming?
The Lexar NM790. Its 7,400 MB/s reads and 6,500 MB/s writes beat the SN5000's 5,500/5,000, and it costs less right now. In practice both load games quickly, since game load times depend more on random reads than peak sequential speed.
Which fits a PS5?
The NM790 is listed as PS5-compatible, but you need to add a heatsink. The SN5000 is listed for PC only, so check Sony's requirements before using it in a console.
Which is better for a thin laptop?
The WD Blue SN5000. It is single-sided, which fits tight M.2 slots, and draws 75 mW active. Check your laptop's slot length and clearance before buying either.
Is the WD Blue SN5000 worth the extra $35?
Only if you need the single-sided fit, the Acronis backup download or the lower power draw. On speed and price the NM790 wins.
Which lasts longer?
Neither listing states endurance or warranty figures, so compare the TBW rating for the exact capacity you buy. Higher-capacity drives usually carry higher endurance.
Does either come with backup software?
The WD Blue SN5000 includes a free Acronis download and software encryption. The NM790 listing does not mention either.
