SAMSUNG 990 PRO 1TB M.2 2280 PCIe 4.0 NVMe internal SSD

SKU CH-NX7F-G3JPR

1TB M.2 2280 PCIe 4.0 NVMe SSD reaching 7450 MB/s read and 6900 MB/s write with 55% faster random performance and 50% better efficiency per watt

  • Device TypeInternal Solid State Drive (SSD)
  • Sequential reads reach 7450 MB/s for near PCIe 4.0 limits
  • Sequential writes hit 6900 MB/s to accelerate large file transfers
  • Random performance improves 55 % over the 980 PRO for snappier heavy workloads
  • Power efficiency rises 50 % per watt versus the 980 PRO reducing heat
  • Nickel-coated controller manages thermals so sustained speeds stay consistent

1 TB PCIe 4.0 NVMe drive

The Samsung 990 PRO is a 1 TB M.2 2280 solid-state drive that connects through a PCIe 4.0 x4 interface using NVMe 2.0. It targets enthusiasts who want fast load times for gaming, video editing and heavy data workloads. The drive supports TCG Opal 2.0 encryption for data security.

Capacity and headroom

At 1 TB the drive holds a large game library, project files and operating system with room to spare. Sequential reads reach 7450 MBps and writes reach 6900 MBps, pushing close to the PCIe 4.0 ceiling. Random performance improves by more than 55 percent over the 980 PRO, so heavy multitasking stays responsive. Sustained writes will eventually hit the controller thermal limit and throttle.

Upgrade path from 980 PRO

Moving from a 980 PRO to this 990 PRO yields a 55 percent random-performance gain and up to 50 percent better performance per watt. The nickel-coated controller runs cooler, reducing throttling during long sessions. The jump is worth it when workloads demand consistently high random IOPS or when power efficiency matters for a compact build.

Questions about this item

Will the M.2 2280 PCIe 4.0 x4 NVMe 2.0 interface work in my older motherboard that only has a PCIe 3.0 M.2 slot?

Yes, the drive is backward compatible and will operate at PCIe 3.0 speeds in an older slot, though you will not reach the maximum 7450 MBps read or 6900 MBps write speeds.

How can I verify the Samsung 990 PRO 1TB is running at its advertised PCIe Gen 4.0 x4 NVMe 2.0 speeds after installation?

Run a benchmark tool such as CrystalDiskMark; expect sequential read results near 7450 MBps and write near 6900 MBps, and confirm the drive reports a PCIe 4.0 x4 link in the OS device manager.

Does the Samsung MZ-V9P1T0B/AM 990 PRO 1TB retail box include a heatsink or mounting screw, or must I buy them separately?

The drive is sold as a bare M.2 2280 module; a motherboard standoff screw is typically required, and a heatsink is optional but recommended for sustained workloads.
