Buying advice

Which should you buy?

The 9100 PRO 2TB is the clear pick on raw spec strength, leading by 46.3 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 MX500 1TB 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 9100 PRO 2TB if you care most about sequential read / sequential write. Its strongest claims are sequential read, sequential write, endurance (tbw), among others.

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

Bottom line: the 9100 PRO 2TB is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
