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 T710 1TB — same S-tier capability for System Drive, about $280 cheaper · Value 100.
Neither of the two above is the only answer — this one clears the same bar for less. ⇄ Compare all three
