Why Choose This Product?

• Purpose-built for HPE ProLiant environments: HPE identifies 726537-B21 specifically as a 9.5mm SATA DVD-RW drive for ProLiant Gen9 servers, reducing uncertainty compared with generic optical drives. 
• Read and write flexibility: DVD-RW capability lets administrators both access existing media and create supported writable discs.
• Broad media compatibility: Support for multiple DVD and CD formats makes the drive useful across installation, recovery, archiving and data-transfer workflows. 
• Compact internal design: The 9.5mm form factor provides optical-media functionality without requiring an external enclosure or consuming a larger drive bay.
• Useful for physical-media workflows: Particularly valuable for environments that still require locally supplied installation media, recovery discs, software media or archives.
• Clear OEM procurement path: 726537-B21 provides an exact HPE option number for RFQs, replacement orders and asset records.
• DVD-RW over DVD-ROM: Compared with 726536-B21, the DVD-RW model adds writable optical-media functionality rather than limiting the deployment to read-only optical media. 
• Defined lifecycle support: HPE publishes product dimensions, performance specifications and warranty terms, giving procurement teams measurable criteria for configuration and replacement decisions.
