What this document does and does not state

WD6004FZBX is one orderable part number in the WD_BLACK family. The data sheet prints no MTBF figure and no annualized-workload row for this line, so neither is asserted here; sustained (internal) transfer rate is likewise not asserted on the part page. The data sheet publishes no temperature-grade or qualification standard and no lifecycle statement, so none is claimed.

Data source

Figures are taken from the manufacturer data sheet WD_BLACK 3.5-Inch Gaming Hard Drive — Western Digital Data Sheet (©2025), Recording Technology=CMR per-code, RPM 7200. No public datasheet link is claimed and the external reference points to the manufacturer product page.
