Where this model’s figures come from

The WD30EZAZ is a single orderable part number in the WD Blue family, but it is not among the model numbers printed in the per-model specification table of the WD Blue data sheet — that table covers other WD Blue capacities and CMR codes. Every figure on this page is taken from the manufacturer’s product page titled “3TB WD Blue PC Desktop Hard Drive”, read on 2026-10-28.

What this page does and does not state

Because the data sheet carries no row for the WD30EZAZ, several parameters this site publishes for other WD Blue models are deliberately not asserted here: the sustained transfer rate (the product page prints “up to 180MB/s” as a line-wide figure that also appears on sibling CMR models, so it is not claimed as specific to this code), the sector format, and an MTBF or workload figure. The capacity 3TB is also offered by this family in a CMR variant, so capacity alone does not identify this code. The manufacturer publishes no operating-temperature grade, qualification standard, or lifecycle status for this line, so none is claimed.

Data source

Figures are taken from the manufacturer’s WD Blue product page for this model (westerndigital.com), captured 2026-10-28, and cross-checked against the WD Blue data sheet, whose per-model table does not contain this model number. No public datasheet link is claimed and the external reference points to the manufacturer product page.
