Where this model’s figures come from
The WD241PURP is an orderable part number in the WD Purple Pro family, and it is not in any current data sheet in this library — the only WD Purple Pro document received so far is a Technical Reference Manual, not a per-model data sheet. Figures here are therefore taken from the manufacturer’s product page for this model line, where capacity and cache are listed per model in the Additional-Models picker, read on 2026-10-28.
What this page does and does not state
Several parameters are deliberately not asserted: the sustained transfer rate and the drive’s capacity shown in the product page’s per-model spec card are unreliable because the page’s comparison fields bleed across neighbouring models, so capacity is taken only from the Additional-Models roster; the manufacturer’s own product page and third-party references disagree on the operating-temperature range for some capacities, so no operating-temperature figure is claimed; no MTBF, sector-format or interface-generation figure is asserted; and no temperature-grade, qualification standard or lifecycle statement is made. A store navigation label “Final Production” is a catalogue section, not a status claim.
Data source
Figures are taken from the manufacturer’s WD Purple Pro product page (WD Purple Pro product page (westerndigital.com, wd-purple-pro-sata-hdd), captured 2026-10-28 (Additional-Models roster + per-SKU spec cards)). No public datasheet link is claimed and the external reference points to the manufacturer product page.
