Cons
- Lacks dedicated DRAM, relying on Host Memory Buffer (HMB) 3.0, which can slightly impact performance in the most intensive games.
- Some demanding titles may push the HMB-based drive to its performance limits.
- The 1TB capacity might be limiting for users with extensive game libraries or large creative projects.
Dimension Scores
With 7400 MB/s read and 6500 MB/s write, it offers near top-tier PCIe Gen4 speeds.
It has a 1000 TBW endurance rating for the 1TB model and a 5-year limited warranty.
1TB is a common and practical capacity for many users, especially for a primary game drive or OS drive.
It's explicitly compatible with desktops, laptops, and the PlayStation 5, covering major use cases for an M.2 NVMe SSD.
Best For
- PC gamers seeking faster game load times and smoother gameplay on a PCIe Gen4 system.
- PlayStation 5 owners looking to expand storage with a compatible, high-speed drive.
- Content creators working with large files who need quick data access and transfer speeds.
- Laptop users prioritizing power efficiency for extended battery life during demanding tasks.
Not Recommended For
- Users with PCIe Gen3 motherboards, as they won't fully utilize the drive's Gen4 speeds.
- Professionals requiring sustained peak performance under extremely heavy, continuous workloads where a DRAM-equipped drive might offer more consistent performance.
Watch Out For
- The drive is DRAM-less, using HMB 3.0 instead, which TechRadar noted can lead to performance impacts in the most intensive games.
- While the heatsink is effective, some demanding applications might still push the drive's performance limits due to its HMB design.
- The 1TB capacity, while substantial, may require frequent data management for users with very large game installations or extensive media libraries.

What Buyers Say
Users frequently point out the Lexar NM790's strong performance for its price point, especially considering it's a DRAM-less drive. Many appreciate its suitability for PlayStation 5 expansion and PC gaming, with TechRadar noting its heatsink effectively prevents thermal throttling. The power efficiency is also a recurring positive, making it a viable option for laptops. However, some reviews, like TechRadar's, mention that its HMB design can lead to slight performance dips in the most demanding game titles.
“Dude, this thing flies in my PS5, games load so fast now, totally worth it for the price, no more deleting stuff every other week!”
Common Praise
- Achieves advertised speeds of 7400 MB/s read and 6500 MB/s write in real-world use.
- The integrated heatsink effectively manages temperatures, preventing performance drops during heavy use.
- Works without issues in PlayStation 5 consoles, providing a noticeable storage upgrade.
- Consumes less power, which is beneficial for laptop battery life.
- Offers a strong performance-to-cost ratio for a PCIe Gen4 SSD.
Common Complaints
- Performance can be slightly inconsistent in extremely demanding, sustained workloads compared to drives with dedicated DRAM.
- Some users might find the 1TB capacity restrictive for very large game libraries or extensive creative projects.
- While rare, some users have received versions without a heatsink, though this specific model is advertised with one.
Ownership Tips

Buying Guide
When you're looking at an SSD like this, you need to think about how you'll use it. If you're just storing documents, you don't need these speeds. But if you're loading massive game worlds or editing 4K video, those high read and write numbers mean less waiting. The heatsink is a big deal if you're pushing the drive hard, especially in a PS5 or a compact PC, because it keeps the drive from slowing down when it gets hot.
Read/Write Speed (MB/s)
This tells you how fast the drive can open files (read) and save files (write). Higher numbers, like 7400 MB/s read, mean games load quicker and large video files transfer in seconds, not minutes.
PCIe Gen4 NVMe
This is the connection type. PCIe Gen4 is the current fast standard, offering significantly more bandwidth than older Gen3 drives. NVMe is a protocol that lets SSDs talk directly to your system, making them much faster than older SATA SSDs.
Heatsink
SSDs generate heat, especially fast ones. A heatsink is like a little radiator that helps dissipate that heat, preventing the drive from 'throttling' or slowing down to protect itself when it gets too hot. This is crucial for sustained performance.
TBW (Total Bytes Written)
This number, like 1000 TBW for the 1TB model, indicates how much data can be written to the drive over its lifetime before it might start to degrade. Higher TBW means a longer lifespan, especially for heavy users.
Alternatives
If this drive doesn't quite fit, consider models with dedicated DRAM for more consistent performance under extreme, sustained loads, or look for higher capacities like 2TB or 4TB if you need more space for your digital life.
