Capacity tiers are index medians; named rows are current buyable listings with condition data. Data through Jul 24, 2026.
Notable capacity moves
12TB is the lowest current median $/TB capacity tier in the index at $35.83/TB. 12TB posted the clearest 30-day move at -12.2%. The lowest-median index tier 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 refurb at BestBuy for $646.99 ($23.11/TB); Toshiba N300 HDWG51JXZSTA 18TB new CMR at BestBuy for $451.55 ($25.09/TB); Seagate Expansion STKP22000400 22TB new at BestBuy for $629.99 ($28.64/TB); Seagate Expansion STKP28000400 28TB new at BestBuy for $849.99 ($30.36/TB). If recertified or refurbished drives are off the table, compare against Toshiba N300 HDWG51JXZSTA 18TB new CMR at BestBuy for $451.55 ($25.09/TB) and Seagate Expansion STKP22000400 22TB new at BestBuy for $629.99 ($28.64/TB). These are not interchangeable: condition and recording tech matter before the lowest $/TB row becomes a buyable recommendation.
