Our take on the Samsung 990 PRO M.2 NVMe PCIe 4.0 SSD

The Samsung 990 PRO is a PCIe 4.0 NVMe M.2 SSD built for speed: sequential reads up to 7450 MB/s and writes up to 6900 MB/s, close to the ceiling of the PCIe 4.0 interface. Samsung claims random read/write of up to 1400K/1550K IOPS, roughly 40% and 55% above the 980 PRO, with over 50% better performance per watt. A nickel-coated controller, a heat-spreader label and Dynamic Thermal Guard manage heat. It suits gamers, video and 3D editors, and anyone moving large files; PCIe 5.0 drives beat it on peak speed but run hotter and cost more per gigabyte.

Pros
  • Near the top of PCIe 4.0 sequential speed
  • Big jump in random IOPS over the 980 PRO
  • Improved performance per watt over the 980 PRO
  • Heat spreader label and Dynamic Thermal Guard
  • Samsung's own controller and NAND
  • Up to 4TB capacity
Cons
  • PCIe 5.0 drives are faster on paper
  • Sustained writes can slow once the cache fills
  • Runs warm under long heavy writes without a heatsink
  • Premium tier pricing versus budget PCIe 4.0 drives

What reviewers say

Owners and reviewers rate the 990 PRO as one of the fastest PCIe 4.0 drives, with real gains in game loads and large file transfers over the 980 PRO. Complaints center on heat under sustained writes and on the price premium over cheaper PCIe 4.0 drives.

What people mention
  • SpeedPraisedReviewers measure sequential reads near 7450 MB/s and call it one of the fastest PCIe 4.0 drives.
  • HeatCriticisedOwners report high temperatures under sustained writes, especially without a heatsink.
  • Power efficiencyPraisedReviewers note it draws less power per unit of performance than the 980 PRO.
  • ValueMixedSome say the premium over budget PCIe 4.0 drives is hard to justify for casual use.
  • Gaming loadsPraisedPlayers report faster game and level load times than with older SATA and PCIe 3.0 drives.

About the Samsung 990 PRO M.2 NVMe PCIe 4.0 SSD

The Samsung 990 PRO is an M.2 (2280) NVMe solid state drive that uses a PCIe 4.0 x4 interface. It reads at up to 7,450 MB/s and writes at up to 6,900 MB/s. It is made for gaming, video and 3D editing, and data analysis, and it works in PCs and game consoles, including the PlayStation 5.

The drive uses Samsung V-NAND, a Samsung in-house controller and Samsung low-power DDR4 cache memory. The controller is nickel-coated, and a heat spreader label helps manage heat from the NAND chips. Dynamic Thermal Guard keeps temperatures in range.

Samsung Magician software handles drive management. It can protect data, deliver firmware updates and monitor the drive's health. The drive works with computers and motherboards that support M.2 NVMe SSDs.

Questions and answers

Is the 990 PRO worth it over the 980 PRO?
Yes if you want the fastest PCIe 4.0 drive Samsung makes: random speeds are up roughly 40% to 55% and it uses less power per watt. For light everyday use the difference is small.
Does it work in a PS5?
Yes, it meets the PS5's M.2 PCIe 4.0 requirements. Sony recommends a heatsink, so pick the version with one or add your own.
Do I need a heatsink?
For a desktop with good airflow the heat-spreader label is usually enough. For sustained heavy writes, tight laptop slots or a PS5, a heatsink version is the safer choice.
What capacities are there?
Samsung sells it in 1TB, 2TB and 4TB. The 4TB model is the one aimed at large game and project libraries.
Is it faster than a PCIe 5.0 SSD?
No. PCIe 5.0 drives reach higher sequential speeds, but they run hotter and cost more. The 990 PRO stays close to the PCIe 4.0 limit with lower power draw.
What is in the box?
The drive itself, with Samsung's heat-spreader label fitted. Screws and mounting hardware are not included; check your motherboard or PS5 kit.
Where is the Samsung 990 PRO M.2 NVMe PCIe 4.0 SSD cheapest?
