| Segment | What it means | Source |
|---|---|---|
| WUH | Ultrastar DC HC series, helium-filled. | Western Digital |
| 722020 | Capacity and generation field. The leading digits encode capacity in the family's own scheme; each model's own specification sheet states its exact capacity. | Western Digital |

| 604 | Not sourced - we have not found a WD document defining this segment. | Not sourced |
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 WD - 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: Western Digital - Ultrastar model-number nomenclature.

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 WD directly before buying. We do not link a checker for this manufacturer because we have not verified one.

WUH722020ALE604 is WD Ultrastar HC560 SATA-6G. 3 of its 4 segments are defined in WD's own published documentation - the decode table on this page shows each one with the document that defines it. For the remaining segments we have not found a defining document, and we say so rather than repeating a community guess as fact.
Not necessarily, and the part number cannot tell you. Coverage depends on how the individual unit entered the market and whether it was registered, not on its model designation. OEM and gray-market stock reaches the market under manufacturer part numbers regularly and frequently carries no manufacturer warranty at all - some retailers print exactly that on the listing. Check the specific serial with the manufacturer before buying.
We track 2 live listings carrying this part number, shown above with condition and cost per terabyte. Prices come from Amazon US and are re-checked continuously; the buy links go to the live listing because the price can change between our check and your click.
Because more than one organisation names it. The manufacturer assigns a model number describing the product; a server vendor buying it in volume assigns its own spare-part number for its service catalogue; distributors sometimes add another. All identify the same physical drive, which is why one number returns listings that look like a different product. Our part number index explains the pattern per vendor.
