Lexar NM790 vs WD Green SN3000 NVMe SSD

The Lexar NM790 is the faster drive and the better pick for gaming, video editing and PS5 use. It reads up to 7,400 MB/s and writes up to 6,500 MB/s, well ahead of the WD Green SN3000 at 5,000 and 4,200 MB/s. The NM790 also comes in far more capacities, up to 8 TB, and owners rate it highly. The SN3000 is a solid everyday drive for a basic PC build, but it is the slower, lower-tier option here.

  • Choose the Lexar NM790 if you want top Gen4 speed for gaming, large file work or a PS5, or you need a capacity above 2 TB.
  • Choose the WD Green SN3000 if you want a dependable Gen4 drive for everyday PC use and don't need the fastest speeds.

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.

What people mention
  • SpeedPraisedUsers highlight the fast read speeds, especially for gaming and large file transfers.
  • PS5 compatibilityPraisedMany mention it works perfectly in the PlayStation 5 for expanded storage.
  • ValuePraisedReviewers often say it offers great performance for the price.
  • Write performanceMixedSome note that write speeds can slow during large sustained writes due to the lack of DRAM.

WD Green SN3000 NVMe SSD

  • 4.8 / 5716 ratings

Rated 4.8 out of 5 from 716 ratings, buyers mostly treat it as a fast, cheap boot and game drive. Complaints center on write speeds falling off during large transfers.

What people mention
  • SpeedPraisedBuyers say boot times and game loads improve clearly over older SATA drives.
  • Sustained writesCriticisedLarge transfers slow down once the cache is used up, which owners notice when copying big files.
  • ValuePraisedOwners see it as one of the cheaper ways to get Gen4 read speeds.

Questions and answers

Which is better for gaming?
The Lexar NM790. Its higher read and write speeds load games and large assets faster, and it is listed as PS5 compatible.
Which lasts longer?
Both are consumer SSDs with similar endurance classes. The NM790's lower power draw helps it run cooler, which is good for long sessions, while the SN3000 adds shock and vibration tolerance.
Is the NM790 worth stepping up to?
Yes for gaming, video work or a PS5. The speed gap is large. For a basic office PC, the SN3000 is enough.
Does the NM790 need a heatsink?
It runs warm under sustained writes. Use your motherboard's M.2 heatsink or a PS5's built-in cover for heavy workloads.
Will both fit my laptop?
Both are M.2 2280 drives, so check that your laptop has a free Gen4 M.2 slot and enough clearance.
Do either have a DRAM cache?
No. The NM790 uses HMB 3.0 and Dynamic SLC Cache, and the SN3000 uses WD nCache 4.0. Both rely on host memory and SLC caching instead of dedicated DRAM.
