Supermicro 3.5" to 2.5" Drive Adapter (Gen 5.5) MCP-220-00166-0B

The Supermicro 3.5" to 2.5" Drive Adapter (Gen 5.5) MCP-220-00166-0B is a mechanical carrier designed to mount a 2.5" drive in a standard 3.5" drive bay. It is intended for use in server and storage systems where precise drive positioning and mechanical stability are critical for reliable operation.

This adapter provides a fixed, secure seating for a 2.5" drive, helping maintain consistent alignment with the bay and backplane. This is particularly important in dense rack systems, where vibration, frequent maintenance and high thermal loads can affect long-term drive reliability.

• Form factor adaptation – enables installation of a 2.5" drive into a 3.5" bay, supporting flexible storage configurations in existing chassis.
• Stable mechanical mounting – ensures firm, repeatable positioning of the drive, reducing the risk of misalignment in server and storage environments.
• Designed for Supermicro platforms – suitable for integration with Supermicro systems using Gen 5.5 mechanical standards (exact chassis compatibility should be verified in Supermicro documentation).
• Service-friendly design – simplifies drive handling during installation, replacement and maintenance in rack-mounted equipment.

Application

• Data center servers and storage nodes requiring 2.5" drives in 3.5" bays.
• Infrastructure upgrades where existing chassis must be reused with newer 2.5" media.
• Environments with frequent drive swaps, where robust mechanical support is essential.

For detailed mechanical dimensions, supported drive types and specific chassis compatibility, refer to the official Supermicro documentation for MCP-220-00166-0B and your server model.
