Product overview

Seagate lists 9ZM278-150 as a Constellation ES.3 3TB 7200RPM SAS 3.5-Inch HDD. Vendor-keyed firmware is the usual reason a mechanically identical drive is rejected by the controller, and a 3TB spare is not worth discovering that on. We check the firmware family against your controller before the drive ships.

Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

What you get ordering this from us

Ordered by part number

Quoted and supplied against 9ZM278-150 specifically, so what arrives is what your build sheet asks for.

Compatibility checked

We confirm the part is supported on your platform before it ships, rather than leaving the check to you.

Firmware family matched

A mechanically identical drive with the wrong firmware is rejected by the controller; we check the family, not just the capacity.

Questions buyers ask about this part

Is 9ZM278-150 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 9ZM278-150 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, POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

Specifying a system, not just the part?

Bulk capacity usually sits behind the flash tier that feeds a training cluster rather than under it.
