Our take on the Samsung 990 PRO 1TB NVMe M.2 2280 PCIe Gen4x4 Internal SSD
The Samsung 990 PRO is a PCIe 4.0 x4 M.2 2280 NVMe SSD with 1TB of capacity, built on Samsung's own controller and V-NAND. It is one of the fastest Gen4 drives you can buy, with sequential reads near the 7,450 MB/s ceiling of the interface and random performance that keeps up under heavy load. It suits gamers, video editors and anyone moving large files who has a Gen4 M.2 slot. Against Gen5 drives it gives up peak speed but runs cooler and draws less power, and against budget Gen4 drives it costs more for consistently higher throughput and better sustained writes.
- Near the top of PCIe 4.0 speed for sequential reads and writes
- Strong random performance for games and everyday work
- Sustained writes hold up better than many budget Gen4 drives
- Samsung Magician software for firmware, health and over-provisioning
- Five-year limited warranty

Questions and answers
- Is the 990 PRO worth it over a cheaper Gen4 SSD?
- If you move large files or want consistent speed under load, yes. For browsing and office work a mainstream Gen4 drive feels much the same.
- Does it fit a PlayStation 5?
- It is an M.2 2280 PCIe 4.0 drive, which matches the PS5 slot. Sony requires a heatsink for added drives, so pick a version with one or add your own.
- Do I need a heatsink?
- For desktops with good airflow, usually not. In laptops, tight cases or long sustained writes, a heatsink version keeps temperatures in check.
- How does it compare with the 980 PRO?
- The 990 PRO is faster, especially in random reads and writes, and more power efficient. The 980 PRO remains capable but is a step behind.
- Is it compatible with my motherboard?
- It needs an M.2 slot wired for PCIe 4.0 x4; it also works in PCIe 3.0 slots at lower speed. Check your board's M.2 keying and length support.
- What is in the box?
- The drive itself and documentation. Screws and heatsinks are not included, so check whether your motherboard or laptop provides mounting hardware.
