Questions buyers ask about this part
Is ST3450857SS 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 ST3450857SS 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.
