Buying advice

Which should you buy?

The 980 PRO 2TB is the clear pick on raw spec strength, leading by 22.9 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

The 870 EVO 1TB doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.

Pick the 980 PRO 2TB if you care most about sequential read and sequential write. Its strongest claims are sequential read, sequential write, capacity, among others.

There are no meaningful ties on the headline specs — every popular-comparison metric has a winner.

Bottom line: the 980 PRO 2TB is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
