Know before you buy
Yes, the NM790 meets the performance requirements for the PlayStation 5. Its M.2 2280 form factor fits perfectly into the console's expansion slot, providing a significant storage boost for your game library.
While the drive is designed to be energy-efficient and run cooler than many DRAM-enabled alternatives, we recommend checking if your motherboard or PS5 setup has an integrated M.2 heatsink. If your device lacks one, adding an aftermarket heatsink is a good practice for sustained heavy workloads.
The NM790 is engineered to consume up to 40% less power than traditional PCIe Gen 4 SSDs that use DRAM cache. This makes it an excellent choice for laptops where battery life is a priority, as it generates less heat and places less strain on your system's power supply.
This drive is built for longevity, featuring a 3000TBW (Terabytes Written) rating and a 1,500,000-hour MTBF. It is designed to handle demanding creative workflows and intense gaming sessions reliably over the long term.
The NM790 is backward compatible with PCIe Gen 3 slots, but it will be limited to Gen 3 speeds. To experience the full 7400MB/s read speeds, you will need a motherboard or device that supports the PCIe Gen 4 interface.
