## Summary description

Icy Dock MB741V4P-B is a drive bay adapter that converts a single PCIe 4.0 NVMe U.2/U.3 device to an MCIO 1x 3.5" bay. Designed for server and workstation use, it enables installation of U.2/U.3 NVMe drives into a 3.5" chassis slot while preserving PCIe 4.0 bandwidth. Useful for storage upgrades, hot-swap enclosures, and integrating enterprise NVMe drives into systems with 3.5" bays.

## Long description

The icy dock MB741V4P-B is a drive bay adapter that allows a single PCIe 4.0 NVMe U.2 or U.3 device to be installed in a standard MCIO 1x 3.5" bay. Designed for server and workstation environments, this adapter preserves PCIe 4.0 bandwidth while converting the U.2/U.3 connector and form factor into a hot-swappable 3.5" bay solution. It is intended to simplify integration of enterprise NVMe drives into chassis that lack native U.2/U.3 bays, supporting storage upgrades and hot-swap enclosure configurations without compromising performance.
Advantages
The adapter maintains PCIe 4.0 link speeds for NVMe drives, enabling full utilization of supported device throughput. Its mechanical design fits a single MCIO 1x 3.5" bay and provides a hot-swap compatible front access, reducing service time in rack and tower systems. The product is compatible with both U.2 and U.3 NVMe interfaces, offering flexibility when migrating between drive generations or using different enterprise NVMe models.
Suitable for
Integrating enterprise U.2/U.3 NVMe drives into systems with 3.5" bays
Hot-swap storage enclosures and server chassis
Workstation storage upgrades where PCIe 4.0 performance must be preserved
Data center and lab environments requiring quick drive replacement
Key specifications
Interface support: PCIe 4.0 NVMe (U.2 / U.3)
Form factor conversion: MCIO 1x 3.5" bay to single U.2/U.3 drive
Drive compatibility: 2.5" U.2/U.3 NVMe SSD (standard enterprise thickness)
Hot-swap capable front access for drive removal and insertion
Material and finish: metal chassis compatible with server mounting (vented front for airflow)
How to use
Install the adapter into an available MCIO 1x 3.5" bay in your chassis following the hardware mounting points and secure it with the provided screws. Insert a compatible U.2 or U.3 NVMe SSD into the adapter connector and ensure the drive is seated firmly. Connect the system cabling required by your chassis and backplane; the adapter preserves the PCIe 4.0 electrical connection to the drive. After mounting and connection, power on the system and verify that the NVMe device is detected by the operating system and firmware.
Usage recommendations
Use this adapter in systems that support PCIe 4.0 to achieve maximum performance. Ensure proper airflow and cooling inside the chassis when installing high-performance NVMe drives. For hot-swap environments, follow your server or enclosure manufacturers procedures for safe drive insertion and removal to avoid data loss.
