Weekly Storage Price Briefing: 22TB Leads the Index, 16TB Leads Listings
This week's read: capacity medians and buyable listings split. 22TB is the best capacity tier by median $/TB, while the sharpest named row is Seagate Expansion STKP16000400 16TB new at BestBuy for $317.99 ($19.87/TB). Capacity tiers are index medians; named rows are current buyable listings with condition data. Data through May 19, 2026.
Notable capacity moves
22TB is the lowest current capacity tier in the index at $28.42/TB. 22TB had the clearest 30-day move at +0.8%, so there is no meaningful downward capacity-tier move this week. 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 Expansion STKP16000400 16TB new at BestBuy for $317.99 ($19.87/TB); Seagate Exos ST28000NM000C 28TB recert at ServerPartDeals for $610.00 ($21.79/TB); Seagate ST26000NM000C 26TB recert CMR at ServerPartDeals for $575.00 ($22.12/TB); Seagate STKP20000400 20TB new at BestBuy for $449.99 ($22.50/TB). For new-condition only, compare Seagate Expansion STKP16000400 16TB new at BestBuy for $317.99 ($19.87/TB) and Seagate STKP20000400 20TB new at BestBuy for $449.99 ($22.50/TB). These are not interchangeable: condition and recording tech matter before the lowest $/TB row becomes a buyable recommendation.
Market lows
12TB has the lowest 30-day index average at $25.00/TB. Listing-level lows worth checking now: Western Digital Gold WD241KRYZ 24TB new at BestBuy is at $23.12/TB; Dell 12TB new at Newegg is at $23.33/TB.
