Where it stands in the field

Two different questions, side by side. Performance compares what the hardware can do; Value compares what that capability costs at today’s price. A product can rank high on one and low on the other — that gap is the point.

Balanced has no letter: it is a weighting preset, not a capability rubric. A grade answers “how well does this handle that job?” — price is never part of it. Relative Value puts the current market price back in.

Trade-offs

Works well if

  • System Drive is your main prioritygraded A for System Drive on the same rubric as the tier list

Consider other options if

  • You want strong value with Balanced priorities specificallyat today's market no realistic price for this model reaches strong value with Balanced priorities — the calculation only gets there near $107, against a cheapest tracked $199

Summary

Computed conclusion

Western Digital SN770M 1TB offers a balanced view across an all-round mix of priorities. It ranks #120 by capability in the current modelled field. Its clearest measured strength is drive capability 5150. Crucial P510 1TB currently clears the same practical bar with stronger Relative Value.

FAQ

Why does Relative Value change when I choose another scenario?

Each scenario changes the weights applied to capability, price and the other published factors. The hardware facts stay fixed, but the value question changes, so its score and rank can change too.

Why can Amazon appear without a tracked price?

Amazon is shown as a discovery link when we do not have a permitted verified price snapshot. It is excluded from price comparisons, rankings and Relative Value until a compliant tracked price exists.
