Buying advice

Which should you buy?

The Platinum P51 2TB is the clear pick on raw spec strength, leading by 23.4 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 980 PRO 2TB does not pull ahead on any single popular-comparison spec — its strengths sit in the spec-table groups rather than the headline advantages.

Pick the Platinum P51 2TB if you care most about sequential write / sequential read. Its strongest claims are sequential write, sequential read, interface.

Both ship with comparable capacity, endurance (tbw), so those specs do not separate the two — focus on the differences below.

Bottom line: the Platinum P51 2TB is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
