Know before you buy
Yes, the NM790 meets the PS5's requirements for an M.2 NVMe SSD. Its PCIe Gen 4x4 interface and 2280 form factor ensure it fits and performs well for console gaming.
While the drive is highly energy-efficient and runs cooler than many alternatives, Sony recommends using a heatsink for PS5 installations. If your laptop or desktop motherboard does not have a built-in M.2 heatsink, you may want to add one to ensure optimal thermal performance during heavy workloads.
The NM790 is designed to consume up to 40% less power than typical PCIe Gen 4 SSDs that use a DRAM cache. This makes it an excellent choice for laptops, as it helps extend battery life without sacrificing significant performance.
This drive is rated for 3000 TBW (Terabytes Written), which indicates a high level of durability. It is designed to handle intensive daily use, including professional creative work and heavy gaming, for many years.
Yes, the drive is backward compatible with PCIe Gen 3 slots. However, you will be limited to the maximum speed of the Gen 3 interface, so you won't be able to reach the full 7400MB/s read speeds.
The NM790 utilizes Host Memory Buffer (HMB) technology rather than a dedicated DRAM cache. This design choice is what allows the drive to remain energy-efficient and cost-effective while still delivering top-tier performance for most users.
