HGST and WD Ultrastar are not competing drive brands in the usual sense. Older HGST-branded generations were carried forward within Western Digital enterprise storage, and refurbished inventory may still be marketed under the historical brand.
Compare the exact model and generation, not the HGST versus WD words alone. He12 corresponds to the DC HC520 generation, and He10 is associated with DC HC510; capacity, interface and condition remain decisive.

Only positively identified Ultrastar-family hard drives qualify. Compare true capacity, model number, seller condition and price per TB. Verified Amazon prices may change.
Potential percentage savings appear only when a fresh Amazon listing includes an independently identified reference price for the same ASIN. If Amazon does not provide a suitable reference price, we show no discount badge.

Compare real buying choices
| Choice | Best use | Check before buying |
|---|---|---|
| Exact family model | Replace a specified HGST disk | Match the full part number, interface and sector format |
| Refurbished offer | Lower initial cost when acceptable | Verify condition, power-on data, returns and seller warranty |
| Other enterprise HDD | Compare total cost for your capacity | Confirm controller/NAS fit and avoid assumed drop-in compatibility |
HGST Ultrastar buying details for this drive family
Practical details that matter when comparing exact HDDs, capacities and configurations.
How the names are connected
HGST became part of Western Digital, and the Ultrastar enterprise HDD line appears under both names in legacy documentation and resale listings. Different labels can therefore refer to related generations rather than rival product lines.
Manufacturers renamed some drive generations: the WD DC HC520 is explicitly described as previously known as He12. Use model codes to resolve ambiguity.
New and legacy inventory
Old HGST-branded drives are disproportionately seen in renewed, recertified and used channels. New WD-branded Ultrastar stock may be from a different generation entirely.
A recent listing date does not imply a recent manufacture date. Compare seller warranty, condition disclosures and the printed model.
Choosing between offers
First specify usable capacity and SATA/SAS support. Next compare the exact SKU, seller and warranty. Finally compare price per TB and expected power, noise and rebuild demands.
The historical HGST logo is not a substitute for correct compatibility or adequate data protection.
What happens if listings are limited?
An older Ultrastar model may have only a few legitimate offers on Amazon at any given time. Rather than display unrelated drives as exact matches, we keep the listing count honest and offer a manufacturer-model search as a separate action.
If no good exact replacement exists, evaluate an approved substitute and confirm its interface, sector format and condition before committing.
How we evaluate an offer
The price cards prioritize a correct part-number family, matching capacity and verifiable interface. Only offers returned by the site’s configured Amazon catalogue can show a verified price, and last-verified observations keep their original age.
We do not manufacture discounts, claim a laboratory test, or present used stock as new. An Amazon offer can change between verification and checkout.

Frequently asked questions
Is HGST Ultrastar the same as WD Ultrastar?
They are connected through Western Digital ownership and the continuation of the Ultrastar enterprise drive line. Check the exact generation and model code; the branding alone does not prove technical identity.
Can a SAS Ultrastar drive be used in a SATA-only NAS?
Usually not. SAS requires appropriate SAS-capable hardware, so check the appliance specifications and the full drive suffix before purchasing.
Is a refurbished HGST Ultrastar safe for important data?
A refurbished drive can be usable, but no single disk should be the only copy of important data. Review seller testing, return rights, SMART health and backups.
Does price per TB tell me which Ultrastar to buy?
Price per TB helps compare capacity cost, but interface, condition, formatted capacity, warranty and system fit are equally important.
