Notes
- Active listings and historical observations are source-grounded. Dashed monthly values are provider-modeled estimates, not observed listings or transactions.
- Modeled estimates cover the current month and previous 12 months and require a grounded observation from the same provider.
- Prices are USD per single item and exclude shipping and tax.
- The supplied identifiers conflict: Lenovo 7XB7A00045 listings identify an 8TB drive, while HUS726T4TAL5204 identifies a 4TB drive. The 8TB Lenovo-part listings were excluded, and exact HUS726T4TAL5204 variants were retained with their tray configuration stated.
- No observation exceeded the one-third-to-three-times median outlier thresholds. Confidence is limited because no active listing matched both the 4TB HUS726T4TAL5204 model and Lenovo tray identity.
- openai validation accepted 16 of 16 raw points.
- Identity conflict in the supplied product fields: grounded Lenovo Press and vendor pages show PN 7XB7A00045 is the ThinkSystem 3.5" 8TB 7.2K SAS 12Gb hot-swap 512e HDD, while the requested 4TB / HUS726T4TAL5204 configuration corresponds to the 4TB ThinkSystem part 7XB7A00043 / 00YK032 and the WD-HGST Ultrastar 4TB SAS drive. Research therefore covers both matching 4TB variants, each preserved in sourceTitle and notes; 8TB-only pages were excluded.
- Excluded candidates: refurbished/brown-box offers, open-box and used marketplace units, NetApp-firmware-locked drives, out-of-stock or backordered vendor pages, non-USD listings, and eBay category, shop, or multi-listing aggregation pages that are not direct single-item product pages.
- Confidence is moderate-to-low: only three new-condition normal-channel comparables qualified, and they span a wide range because bare-drive marketplace supply prices far below new-sealed reseller inventory for the same capacity and interface.
- Search budget used: three current-listing queries; the optional historical query was left unused because no direct dated archive or price-history page for this identity and condition was identified, so the flat modeled fallback applies.
- anthropic validation accepted 17 of 17 raw points.
- Product identity references both the Lenovo ThinkSystem option part number (7XB7A00045) and the HGST/WDC base drive model (HUS726T4TAL5204). Representative listings across both variants were sampled.
- Enterprise replacement distributor pricing at $950.00 was excluded from the baseline anchor calculation because at least three normal-channel comparables were identified.
- gemini validation accepted 17 of 17 raw points.
