Overview of the Samsung 980 Pro M.2 SSD

by

The Samsung 980 Pro M.2 SSD is renowned for its impressive speed and reliability, making it a popular choice among tech enthusiasts and professionals. Its performance varies depending on the device it is installed in, such as laptops and desktops. In this article, we explore speed tests of the Samsung 980 Pro on both laptops and desktops to understand how hardware differences impact performance.

Overview of the Samsung 980 Pro M.2 SSD

The Samsung 980 Pro is a high-performance NVMe SSD built on PCIe 4.0 technology. It offers sequential read speeds up to 7,000 MB/s and write speeds up to 5,000 MB/s. Its advanced controller and NAND technology make it suitable for gaming, content creation, and heavy data processing tasks.

Speed Tests on Laptops

Laptops often have limited thermal management and power constraints, which can influence SSD performance. In recent tests, the Samsung 980 Pro installed in high-end gaming laptops and ultrabooks showed the following results:

  • Sequential Read Speed: 6,800 MB/s to 7,000 MB/s
  • Sequential Write Speed: 4,800 MB/s to 5,200 MB/s
  • Random Read/Write (4K): 700,000 IOPS / 650,000 IOPS

These speeds are close to the SSD’s maximum capabilities but can vary depending on the laptop’s thermal design and PCIe lane allocation. Thinner ultrabooks may experience slight throttling under sustained loads.

Speed Tests on Desktops

Desktops generally provide better thermal management and power delivery, allowing the Samsung 980 Pro to perform at its peak. In dedicated testing environments, desktops showed the following results:

  • Sequential Read Speed: 6,950 MB/s to 7,000 MB/s
  • Sequential Write Speed: 4,900 MB/s to 5,000 MB/s
  • Random Read/Write (4K): 720,000 IOPS / 670,000 IOPS

These results demonstrate that desktops can fully leverage the SSD’s capabilities, providing slightly higher and more consistent speeds during prolonged use.

Factors Affecting Performance

Several factors influence the speed of the Samsung 980 Pro in different devices:

  • Thermal Management: Better cooling in desktops prevents throttling.
  • Power Delivery: Desktops provide stable power, supporting maximum speeds.
  • PCIe Lane Allocation: Laptops may share lanes with other components, limiting bandwidth.
  • Thermal Throttling: Laptops are more prone to thermal throttling during sustained workloads.

Conclusion

The Samsung 980 Pro M.2 SSD performs exceptionally well in both laptops and desktops, with desktops generally providing a slight edge in sustained performance due to better thermal and power management. For users seeking maximum speed, a desktop setup is preferable, but modern high-end laptops still deliver impressive results that make the Samsung 980 Pro a versatile choice for various computing environments.
