Weekly Storage Price Briefing: 25TB Leads the Capacity Value Curve
This week's storage market read covers 28 tracked capacity tiers, with 25TB currently leading the visible $/TB curve.
Notable capacity moves
30TB posted the clearest 30-day move in the tracked capacity index at -67.9%. Read this as a capacity-level signal rather than a single-drive recommendation: the stronger pattern is whether multiple offers in the tier are confirming the same move. If the tier is thin or mostly marketplace inventory, treat the move as a prompt for inspection rather than a settled market reset.
Current best-value drives
25TB is the first tier to check this week, with the current tracked median at $14.40/TB. The practical workflow is still to compare condition, recording technology, warranty clarity, and retailer quality before treating the lowest $/TB row as the best buy.
Market lows
28TB has the lowest 30-day average in the current index at $21.57/TB. If an individual listing sits below that curve and the listing data is clean, it is worth inspecting before chasing smaller nominal discounts elsewhere. This is also the useful benchmark for deciding whether a lower total price is actually cheaper storage.
Short finding
The useful signal this week is clustering, not a one-off price. When the best current tier, the lowest 30-day average, and the biggest mover point toward nearby large capacities, $/TB remains the fastest first-pass filter for NAS and bulk-storage buyers. Data through 2026-04-29.
