Model number

This page is the customer-orderable model number WUH721414AL5200, listed in the data sheet’s Model Numbers table for SAS 12Gb/s models. This data sheet does not publish a frank/part-number table, so no secondary part code is claimed here; the model number above is the manufacturer’s own order code.

What this page does and does not state

All six Ultrastar DC HC530 order codes share the capacity, spindle speed, buffer, recording technology, reliability and warranty figures above — the data sheet prints them as common columns of one specification table. What differs by code, and what is asserted only for this row, is the interface (SAS 12Gb/s) and the data-security option. The data sheet carries no workload-rating row for this family and publishes no temperature-grade/qualification standard or lifecycle statement, so none of that is claimed here. MTBF is given by the manufacturer as a projected estimate, not a measured value.
