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.
The decision, split by questioncapability · value · price are separate answers
Capability by task
| Scenario | Samsung 9100 PRO 2TB | Western Digital SN8100 2TB |
|---|---|---|
| System Drive | S#15 | S#2 |
| Game & File Storage | A#92 | A#51 |
| Heavy Creative Work | S#12 | S#3 |
They grade identically in all 3 graded scenarios — the tier table won't decide this one, so compare price and Value below. These are the same S–F grades as the tier list — capability only, price excluded. The value rows below add prices from the 2026-09-13 offer frame. How tiers are assigned →

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.
09 · 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
Western Digital SN8100 1TB — same S-tier capability for System Drive, about CAD 149 cheaper · Value 83.

11 · Methodology & FAQ
Read the methodology →How to read this comparison
The formula is a linear weighted sum inside the current comparison frame. Capability, price and user priorities stay visible as separate inputs so the result can be challenged and changed.

- Under the balanced preset and the 2026-09-13 offer frame, Western Digital SN8100 2TB has higher Relative Value under this configuration (100 vs 94). Value is price-dependent and moves with your weighting; capability is a separate question, answered by the tier table.
- Which one is more capable, ignoring price?
- They grade identically in all 3 graded scenarios — the tier table won't decide this one, so compare price and Value below.
- At what price does the Samsung 9100 PRO 2TB become the better value?
- Holding the Western Digital SN8100 2TB offer dated in the 2026-09-13 frame fixed, the calculation flips in favour of the Samsung 9100 PRO 2TB at roughly CAD 523 or below (balanced preset). Not a price forecast.
