846523-004 is HP ProLiant OEM 4TB SAS-12G. 2 of its 2 segments are defined in HP's published documentation and decoded below; for the rest we have not found a defining document, and they are marked as such. 1 live listing below.
| Segment | What it means | Source |
|---|---|---|
| 846523 | HPE part identifier. HPE publishes which product each number corresponds to; we have not found an HPE document giving a character-level grammar for this field. | HPE |
| 004 | Spare part number revision. | HPE |
We decode only what the manufacturer documents. There is a large body of community knowledge about the undocumented segments above, much of it probably right, and none of it published by HP - so it does not appear in this table. A reading nobody can check does not belong in a column headed “what it means”. Grammar reference: HPE - spare part numbers and how to find them.
846523-004 is HP ProLiant OEM, a 4TB hard drive on SAS-12G. Being a SAS device, it needs a SAS host bus adapter or backplane - it will not run from a motherboard SATA port, though a SATA drive will run on a SAS controller.

A manufacturer part number does not imply a manufacturer warranty, and this is where part-number buyers lose the most money. OEM stock, integrator pulls and gray-market units all reach the market under the maker's own numbering. Retailers selling them sometimes state plainly that the manufacturer warranty is none; others simply do not mention it, which is not the same as it being covered.
Coverage attaches to the individual unit and its serial number, not to the part number. That means the only reliable answer comes from the manufacturer, about the specific drive you are being sold.
Ask the seller for the serial number and check it with HP directly before buying. We do not link a checker for this manufacturer because we have not verified one.
