02 · Decision matrix
One decision, three separate questions
Capability ignores price. Relative Value adds the current dataset offers and your priorities. Keeping them separate prevents a cheap product from being mistaken for the faster product.

Try other models and your own priorities
Presets are starting points. Swap either side, then open Advanced weights only if you want to tune the formula directly.
08 · Alternative
A third option worth checking
The same scenario and market frame checks whether another currently priced model offers a cleaner trade-off.
Worth considering instead
Crucial T710 1TB — same S-tier capability for System Drive, about $90 cheaper · Value 100.
Neither of the two above is the only answer — this one clears the same bar for less. ⇄ Compare all three

Choose based on the trade-off you actually want
These are evidence-linked conditions, not universal buying verdicts. Feature ecosystems, software support and platform preferences remain your call.
Choose A · Silicon Power UD90 2TB if…
- Your priorities resemble Balanced, System Drive, Game & File Storage — it has higher Relative Value under those presets at the snapshot offers.
Choose B · Crucial P3 Plus 2TB if…
- Its platform or feature fit matters more to you than the tracked scenario and price leads shown here.
