A bargain, but not quite perfect

Lexar NM790 with Heatsink: One-minute review
The Lexar NM790 with Heatsink is one of the best SSDs for PS5 in its price range. Its 4TB variant in particular is significantly cheaper than the competition, especially when it goes on sale. It also scores well in the internal PS5 benchmark, even beating pricey licensed alternatives like the WD Black SN850P and Seagate Game Drive M.2 SSD for PS5.
If your number one priority is getting a high-capacity option with solid performance at the lowest possible cost, then the Lexar NM790 with Heatsink is the clear winner. That said, there are some significant drawbacks that arise with that reduced price tag. The most important is that this is a dynamic random access memory (DRAM)-less model that uses host memory buffer (HMB) technology, something that you would expect from budget PC SSDs rather than ones made with consoles in mind.
The PS5 does not support HMB and Sony even recommends against fitting HMB drives. This is because it leads to somewhat uneven performance, which is noticeable when you’re copying particularly large files. It can also cause issues in games, though these are far from a complete dealbreaker as the vast majority of titles that I tested ran flawlessly, even the likes of Call of Duty: Black Ops 6.
