Where this model’s figures come from
The WD30EFPX is a single orderable part number in the WD Red Plus family, but it is not one of the model numbers printed in the per-model specification table of the WD Red Plus data sheet — that table covers the 2TB, 4TB, 6TB, 8TB, 10TB and 12TB codes. Every figure on this page is taken from the manufacturer’s product page for this model, read on 2026-10-28.
What this page does and does not state
Because the data sheet carries no row for the WD30EFPX, several parameters this site publishes for other WD Red Plus models are deliberately not asserted here: the interface generation figure (the page prints “SATA” without a 6 Gb/s value), the sustained transfer rate, the sector format, and an MTBF figure. The manufacturer publishes no temperature-grade or qualification standard and no lifecycle statement for this model, so none is claimed here.
Data source
Figures are taken from the manufacturer’s WD Red Plus product page (westerndigital.com), captured 2026-10-28, and cross-checked against the WD Red Plus 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.
Who makes it
