Installation scope
Check before ordering
- Match the full manufacturer model, including its suffix, to the offered label. OEM firmware and carrier requirements need a separate check.
- A matching capacity and connector do not establish server compatibility. Check the host support list, controller, backplane, firmware and power budget.
- Confirm the NVMe connector, supported PCIe lanes and cooling. The negotiated PCIe generation and link width depend on the installed host.
- Request SSD health, remaining endurance, firmware and exact-item photos. Published TBW or DWPD ratings do not describe remaining endurance on a used drive.
- An instant-erase variant must not be treated as equivalent to a managed SED variant. Confirm the required security workflow.
Use the complete model number for the requested drive. A carrier or OEM spare number is a separate identifier.
