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.
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
Crucial P310 500GB — same S-tier capability for System Drive, about CAD 44 cheaper · Value 26.
Neither of the two above is the only answer — this one clears the same bar for less. ⇄ Compare all three
10 · Decision guide
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 · Western Digital Green SN3000 1TB if…
- Your priorities resemble Balanced, Game & File Storage, Strict Budget — it has higher Relative Value under those presets at the snapshot offers.
- You can find it at or below its Strong Value threshold of CAD 134 under balanced weights.
Choose B · ADATA LEGEND 860 1TB if…
- You can find it at or below its Strong Value threshold of CAD 134 under balanced weights.
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.
- Which is better value right now: Western Digital Green SN3000 1TB or ADATA LEGEND 860 1TB?
- Under the balanced preset and the 2026-09-13 offer frame, Western Digital Green SN3000 1TB has higher Relative Value under this configuration (53 vs 48). 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 ADATA LEGEND 860 1TB become the better value?
- Holding the Western Digital Green SN3000 1TB offer dated in the 2026-09-13 frame fixed, the calculation flips in favour of the ADATA LEGEND 860 1TB at roughly CAD 240 or below (balanced preset). Not a price forecast.
- Where can I compare current offers for both?
- Dated offer snapshots for both models are listed on their product pages (linked above); the interactive calculator recalculates both with your own weights and budget.
