18TB Leads the Index, 28TB Leads Listings
This week's read: capacity medians and buyable listings split. 18TB is the best capacity tier by median $/TB, while the sharpest named row is Seagate Exos ST28000NM000C 28TB recert at ServerPartDeals for $610.00 ($21.79/TB). Capacity tiers are index medians; named rows are current buyable listings with condition data. Data through Jun 5, 2026.
Notable capacity moves
18TB is the lowest current capacity tier in the index at $25.00/TB. No qualified capacity tier got meaningfully cheaper this week; 18TB stayed closest to flat at 0.0%. The index leader is not the same as the cheapest named listing; use the tier view for market shape and the listing rows for actual buy decisions.
Current best-value drives
Current rows with clear condition data: Seagate Exos ST28000NM000C 28TB recert at ServerPartDeals for $610.00 ($21.79/TB); Seagate Exos ST25000NM000E 25TB recert at ServerPartDeals for $549.00 ($21.96/TB); Toshiba MG07ACA14TE 14TB refurb at ServerPartDeals for $309.00 ($22.07/TB); Seagate ST26000NM000C 26TB recert CMR at ServerPartDeals for $575.00 ($22.12/TB). For new-condition options, open the current new-condition deals before buying; this issue did not name a new-condition comparison. These are not interchangeable: condition and recording tech matter before the lowest $/TB row becomes a buyable recommendation.
