Decision summary

Treat WD4003VRYZ, the photographed HC510 example and the photographed HC530 example as separate procurement identities. Their product-line names and documented SATA interfaces do not establish direct interchangeability or the same platform requirement.

Identify the exact model

Request the complete label and model for every line item. The photographed examples show WD4003VRYZ, HUH721010ALE604 and WUH721414ALE6L4; do not replace those exact identifiers with WD Gold, HC510 or HC530 alone.

Compare interface and format fields

The reviewed examples document SATA 6 Gb/s interfaces and 3.5-inch forms. Confirm the exact sector format and other model-specific fields from the applicable manufacturer document or buyer requirement rather than carrying them between product lines.

Check controller, backplane and bay

Record the server or storage model, controller, backplane, bay, carrier and any OEM or firmware requirement. Review the exact requested identifier against that path before accepting an alternative.

Request condition evidence

Define the required label and diagnostic output for each quoted unit or agreed sample. Keep the first-party product photographs separate from order evidence and state the target condition and acceptance scope in the RFQ.
