18TB Lowest Index Median, 14TB Best Listing
This week's read: capacity medians and buyable listings split. 18TB is the lowest median $/TB capacity tier in the index, while the sharpest named row is Toshiba MG07 MG07ACA14TE 14TB refurb at ServerPartDeals for $354.00 ($25.29/TB). Capacity tiers are index medians; named rows are current buyable listings with condition data. Data through Oct 23, 2026.
Notable capacity moves
18TB is the lowest current median $/TB capacity tier in the index at $41.78/TB. No qualified capacity tier got meaningfully cheaper this week; 10TB stayed closest to flat at -0.7%. 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: Toshiba MG07 MG07ACA14TE 14TB refurb at ServerPartDeals for $354.00 ($25.29/TB); Seagate ST10000NM0096 10TB refurb at ServerPartDeals for $259.00 ($25.90/TB); Seagate ST12000NM002G 12TB refurb at ServerPartDeals for $319.00 ($26.58/TB); Seagate ST10000NM0096 10TB refurb at Newegg for $269.00 ($26.90/TB). If recertified or refurbished drives are off the table, compare against Seagate Expansion STKP16000400 16TB new at Newegg for $459.99 ($28.75/TB) and Seagate Expansion STKP28000400 28TB new at BestBuy for $849.99 ($30.36/TB). These are not interchangeable: condition and recording tech matter before the lowest $/TB row becomes a buyable recommendation.
Market lows
18TB has the lowest 30-day index median at $41.52/TB. A listing-level low worth checking now: HGST Ultrastar HUH721212AL4200 12TB refurb at Newegg is at $29.58/TB. This row is useful because the current listing is at or below its own tracked low; high-priced historical lows are filtered out.
