Lexar NM790 NVMe SSD vs Crucial E100 1TB NVMe SSD

The Lexar NM790 is the faster drive by a wide margin: up to 7,400 MB/s read and 6,500 MB/s write versus 5,000 and 3,000 on the Crucial E100. The NM790 uses TLC flash with HMB and dynamic SLC cache, while the E100 uses QLC flash with no DRAM cache and a lower 80 TBW endurance rating. Owners and reviewers rate the NM790 highly for sustained speed and PS5 fit; the E100 is a basic budget Gen4 drive that beats SATA but trails mainstream Gen4 drives. Buy the NM790 for gaming, video work or a PS5; pick the E100 only for light storage where speed does not matter.

  • Choose the Lexar NM790 if you want near-top Gen4 speed for gaming, large file transfers, video editing or a PlayStation 5.
  • Choose the Crucial E100 if you need a cheap 1 TB Gen4 drive for documents, photos and general storage on a secondary machine.

What reviewers say

Lexar NM790 NVMe SSD

  • 4.9 / 552 ratings

Owners rate the NM790 very highly, calling it fast, cool-running and easy to install. Most praise comes from gamers and laptop upgraders who see near-flagship load times for far less than premium drives. The main complaints concern sustained write speed and the lack of a heatsink.

What people mention
  • SpeedPraisedOwners report quick boots, fast game loads and near-advertised sequential speeds.
  • ThermalsPraisedReviewers note it runs cool and draws little power, which suits laptops and handhelds.
  • ValuePraisedBuyers see it as one of the better Gen 4 drives for the money.
  • Sustained writesCriticisedWrite speed drops once the SLC cache fills on large transfers.

Questions and answers

Which is better for gaming?
The Lexar NM790. Faster reads cut load times and its TLC flash keeps speed up during large installs and updates. The E100 works for games but writes at about half the speed.
Which lasts longer?
The NM790. Its TLC flash and higher endurance rating handle more total writes than the E100's 80 TBW QLC design. The E100 is fine for light use but wears faster under constant large writes.
Is the NM790 worth stepping up to?
Yes for gaming, video editing, large transfers or a PS5. The E100 only makes sense if you want a basic Gen4 drive for storage and do not need speed.
Will either fit a PlayStation 5?
The NM790 is listed as PS5 compatible and meets the speed requirement. The E100 is not marketed for PS5, so check its specs before installing one.
Do either have a DRAM cache?
Neither has dedicated DRAM. The NM790 uses Host Memory Buffer 3.0 to borrow system memory, which helps it stay fast; the E100 has no DRAM cache at all.
Which runs cooler in a laptop?
Both are low-power designs. The NM790 claims up to 40% less power than DRAM-equipped Gen4 drives, and the E100's QLC flash is also efficient, so either suits a laptop.
