HGST 1.2TB (HUC101212CSS600): Recording Status
We have not found a manufacturer document stating the recording technology for this exact part number. We know what the drive is - a HGST 1.2TB SAS-12G hard drive (2.5") that we track - but a recording technology printed without a source is a guess, and for RAID, NAS or ZFS use that guess is the one that matters. That is a statement about what we have found, not about what HGST has published.

The leading digits encode capacity in the family's own scheme; each model's own specification sheet states its exact capacity.

We hold no SAS model with a sourced recording technology to compare against, and a drive on a different interface would not be a fair comparison - so there is no nearest-model link here.

How to settle it for this drive
Read the model number on the drive's own label, then find HGST's data sheet or product manual for that family. A document that prints HUC101212CSS600 in its own row of a recording-technology table settles the question. A family page that names no part numbers does not: we have found maker pages that list neither a part number nor a recording method, and we no longer count them as sources. A retailer listing is not a source either - it is a seller's description, and sellers repeat what other listings say.

When a source turns up
When we find a maker document that names HUC101212CSS600, this page will state the answer with that document linked and the date we read it, the same way our documented pages do. Until then, the honest answer is that we do not know.
