Model overview based on user reviews
The Lexar NM790 is a fast PCIe 4.0 NVMe SSD suited to gaming, everyday workloads, laptops, desktops, and PS5. It combines strong real-world performance with very good power efficiency, while the 3D TLC NAND offers a solid alternative to QLC at higher capacities. The DRAM-less design keeps power use low but can reduce random-write performance, and heavy sustained workloads may cause thermal throttling. Heatsink and bare versions are available.
Pros
Cons
I've been using it for over a year. The SSD is used exclusively for games. It doesn't overheat, and it's fast. Although, the price today is shocking. Whether it's worth today's money - everyone decides for themselves. For the money (around 3,000 EUR) when I bought it - definitely yes. Speed in games, does not heat up, resource 1000TBW (after a year of operation SMART shows 100% health) I haven't found a job in a year.  Vasil: use Lexar LNM790X001T-RNNNG more than year |
Great SSD option, speed is up to par, good durability reserve. Speed, strength, temperature .. The only downside is the price, just like all the others. Cool_bot Zhibulyak: use Lexar LNM790X001T-RNNNG few months |
