Product overview
The Western Digital Gold 12TB 7200RPM SATA 3.5-Inch hard Drive is supplied under part number WD121KRYZ. Replacing a failed drive means matching interface, form factor and firmware to the backplane it is going into. This is a SATA unit. Send us the server model and we will confirm the fit rather than leave you to check it.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

What you get ordering this from us
Ordered by part number
The order is placed against WD121KRYZ, not against a description of it, so there is no room for a substitution you did not agree to.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Spares held to a fleet standard
Tell us the chassis you run and we will keep the spare consistent with what is already in the shelf.
Questions buyers ask about this part
- Is WD121KRYZ genuine and is the warranty intact?
- Yes — new and sealed, with the Western Digital warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will WD121KRYZ work in my server?
- Send the server model or the shelf it is going into. Vendor-keyed firmware is the usual reason an identical-looking drive is rejected, so we check that alongside interface and form factor.
- Do you accept purchase orders and quote at volume?
- Yes. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

Specifying a system, not just the part?
Bulk capacity usually sits behind the flash tier that feeds a training cluster rather than under it.
