Price ratings compare a drive against its own price history and the other listings of that same drive — not against other drives. The $/TB badge is the cross-drive comparison. Neither is a compatibility or reliability recommendation.

    Why this DealScore? (88/100 — Excellent price for this drive)▾

    DealScore rates only whether the price is good right now (0–100), and only for this drive: it blends this listing's own price history with the other live listings of the same model. It is not a comparison against other drives — the $/TB badge does that — and use-case fit (NAS-Safe) and seller risk are scored separately.
