Buying advice

Which should you buy?

The T9 Portable 2TB is the clear pick on raw spec strength, leading by 8.9 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 T9 Portable 2TB if you care most about sequential write and sequential read. Its strongest claims are sequential write, sequential read, capacity, among others.

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

Bottom line: the T9 Portable 2TB is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
