# Seagate BarraCuda 1TB vs 2TB: Which Capacity Is Better Value? Canonical: https://cloudzat.com/seagate-barracuda-1tb-vs-2tb/ Choose 1TB when the drive is a low-cost replacement for a modest secondary-storage need and the exact model and condition are verified. Choose 2TB when the price premium is small, you expect the library to grow, or opening the computer again would cost more than buying the extra capacity now. Compare price per usable terabyte, not only sticker price. Use the canonical page for live or last-verified Amazon pricing and images.
