Overview of Samsung 980 Pro SSDs

by

The Samsung 980 Pro series offers high-performance NVMe SSDs designed for gaming, creative work, and demanding computing tasks. With options of 1TB and 2TB capacities, many users wonder if upgrading to the larger capacity also means a significant increase in speed. This article compares the performance of the Samsung 980 Pro 1TB and 2TB models to help you make an informed decision.

Overview of Samsung 980 Pro SSDs

The Samsung 980 Pro is built using PCIe 4.0 technology, offering faster data transfer rates than PCIe 3.0 drives. Both capacities feature the same controller and NAND flash technology, which means their core specifications are similar. However, the capacity can influence performance, especially in sustained workloads.

Performance Specifications

Below are the key performance metrics for both models:

  • Sequential Read Speed: Up to 7,000 MB/s (both models)
  • Sequential Write Speed: Up to 5,000 MB/s (both models)
  • Random Read IOPS: Up to 1,000,000 IOPS (both models)
  • Random Write IOPS: Up to 1,000,000 IOPS (both models)

As seen, the theoretical maximum speeds are identical for both capacities, indicating that capacity does not affect raw data transfer rates in ideal conditions.

Real-World Performance Differences

While specifications suggest similar speeds, real-world tests often reveal minor differences. Larger capacities tend to maintain higher sustained write speeds due to better thermal management and more NAND chips working simultaneously. This can lead to marginally better performance in intensive tasks like large file transfers or video editing.

Factors Influencing Speed Differences

Several factors can influence the actual speed differences between the 1TB and 2TB models:

  • NAND Flash Chips: More chips in the 2TB model can distribute workloads more effectively.
  • Thermal Management: Larger capacity drives often run cooler, maintaining higher speeds over time.
  • Firmware and Controller: Both models use the same controller, but firmware optimizations may favor larger drives during sustained workloads.

Conclusion: Is the Speed Difference Worth It?

In terms of raw speed, the Samsung 980 Pro 1TB and 2TB are very similar, with maximum sequential and random speeds matching. However, the 2TB model may offer slightly better sustained performance during prolonged intensive use due to its larger NAND array and thermal advantages. If you require the maximum speed for heavy workloads, the 2TB version might provide a marginal benefit.

For most users, the choice between 1TB and 2TB should be based on storage needs and budget, rather than speed differences. Both drives deliver exceptional performance suitable for demanding applications.
