WD Ultrastar DC HC680
Ultrastar DC HC680 is Western Digital's SMR data-center hard-drive family with 28TB, 27TB and 26TB models on the 10-disk helium-sealed OptiNAND platform using UltraSMR (7200 RPM), offered over SATA 6Gb/s only. The October 2024 data sheet lists order codes without a frank part-number table; per-model pages state that honestly.
One datasheet, several ordering codes. Each code keeps its own detail page; this page lists them side by side. Specifications are compiled by our own team — we link to the manufacturer's document, we never host it.

Each ordering code is a separate part page.
The codes above come from the same manufacturer document but differ by capacity, temperature grade, package or lifecycle.
