  "headline": "The cheapest new internal hard drive on Amazon US runs roughly $24–$41 per terabyte, and cost per terabyte barely tracks capacity: in this snapshot 4TB leads at $23.80/TB while 24TB is the priciest at $41.46/TB, with the tiers in between clustered close together. There is no fixed \"cheapest capacity\": which drive wins on cost per TB shifts daily with stock and lightning deals, so the best per-TB buy is whatever tops the live ranking on the day, not a number you saw last month.",
  "citation": "HDDHunt Price-Index (October 2026): the cheapest new internal hard drive on Amazon US runs roughly $24–$41 per terabyte, and cost per terabyte barely tracks capacity — in this October 2026 snapshot 4TB leads at $23.80/TB and 24TB is dearest at $41.46/TB — so the best value per terabyte is whichever drive tops the live ranking rather than a fixed capacity.
