HDD Price Index: Dated Cost per Terabyte for 8TB Drives (2026)

Capture paused on 2026-09-14. The last capture ran on 2026-09-07 and the file ends there: 35 rows across 13 capture dates, 2026-08-12 to 2026-09-07. It will not gain rows while the pause stands. Dated price-per-terabyte observations for 8TB NAS and desktop hard drives at named direct US retailers, captured during the 2026 HDD supply crunch. Every row is a price seen on a retailer's page on that date. It is not a quote, and it says nothing about today's price or stock. Acceptance rules. Named direct US retailers only, no marketplace sellers; new condition only; the listing title must state the exact drive line and capacity. Every rejected listing is logged with its rejection reason. Read this before reusing the data. The retail surface churns enough to manufacture price moves that never happened. Three captures minutes apart on 2026-08-25 disagreed about which drive lines had qualifying offers (703, then 634, then 624 listings reviewed). One WD Red Pro listing read $489.11 and $379.99 twelve minutes apart under the same document id with a different seller. Document id alone is not a listing identity; match on seller as well. Activation gate. The index needed 6 qualifying drive lines in one capture to publish an index row. In 17 captures the most any capture accepted was four, so no index row was ever written. This file holds the underlying observations only. Full method and change log: https://techfuelhq.com/data/hdd-price-index/
