A straight comparison shows the following.

  • The Samsung 980 does not have a 2TB storage size, whereas the 970 Evo Plus does.
  • The R/W speeds of the 980 Evo for the 1TB version are the same as that of the 970 Evo Plus. However, the smaller versions have speeds lower than that of their 970 Evo Plus counterparts.
  • When comparing the 4K Random R/W speeds, the 970 Evo Plus performs better than the 980 Evo for all variants.
  • The endurance levels are identical.

The Samsung 980 features an upgraded intelligent TurboWrite 2.0 that provides enhanced sustained performance by the dynamic SLC buffer storage area inside the SSD.

The Benchmark figures for the 1TB variant put the Samsung 980 Evo at par with the Samsung 970 Evo Plus. Though the sequential read speeds are almost identical, the 980 lags in the write speed by nearly 18%.

However, when it comes to real-world applications, the lag drops to 1.5%. The Samsung 980 is slightly better than the 970 Evo Plus in the 4K Random Read speeds, while it falls behind in the 4K Random Write speeds.

The Samsung 980 is far better in the drive’s responsiveness aspect when running everyday applications.

The PCMark 10 trace test shows the Samsung 980 to be far better than the Samsung 970 Evo Plus. On the energy consumption front, the Samsung 980 performs better by nearly 24% compared to the Samsung 970 Evo Plus.

Overall, the Samsung 980 is a better option, primarily because of its responsiveness, electricity consumption performance, and pricing.
