Product overview
Seagate lists 9Z1066-039 as a 300GB 15000RPM SAS 3Gb/s 16MB cache 3.5-in HDD. Replacing a failed drive means matching interface, form factor and firmware to the backplane it is going into. This is a SAS 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.

Questions buyers ask about this part
Is 9Z1066-039 genuine and is the warranty intact?
Yes, new and sealed, with the Seagate warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will 9Z1066-039 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.
