Icy Dock MB309A PCIe 4.0 M.2 NVMe to SlimSAS Redriver Adapter

The Icy Dock MB309A is a high-performance PCIe 4.0 adapter designed to bridge the gap between M.2 NVMe SSD slots and professional SlimSAS storage systems. This adapter card is engineered to provide a reliable and high-speed connection, ensuring that modern NVMe drives can be integrated into complex server and workstation environments with ease. By utilizing advanced signal conditioning, it maintains data integrity even when using extended cable runs, making it a critical component for professional storage configurations.

Advantages

The primary advantage of this adapter is its integrated PCIe Gen 4.0 redriver and 100MHz clock buffer, which work together to prevent signal degradation and ensure stable transfer speeds of up to 64Gbps. This design allows for flexible system architecture, enabling users to convert internal M.2 slots into external or removable storage bays without sacrificing performance. Its compatibility with the broader Icy Dock EXLink ecosystem simplifies the deployment of modular storage, reducing the complexity of cabling and hardware integration for system builders and IT professionals.

Suitable for

• Professional workstation storage upgrades
• Server-grade NVMe storage expansion
• Industrial PC and edge AI system configurations
• Removable storage workflows requiring high-speed data access

This adapter is not suitable for systems that lack an available M.2 PCIe slot or for motherboards that do not support NVMe protocol communication. It is also not intended for use with SATA-based M.2 drives, as it is specifically optimized for high-speed PCIe NVMe signaling.

Key specifications

• Host interface: PCIe
• Output interface: M.2, SlimSAS 4i (SFF-8654)
• PCIe Standard: Gen 4.0 (backward compatible with Gen 2/3/5)
• Maximum transfer rate: 64Gbps
• Dimensions: 80 mm x 22 mm x 14.8 mm
• Weight: 0.0058 kg

To use the Icy Dock MB309A, insert the adapter into a compatible M.2 M-Key slot on your motherboard or expansion card. Once secured, connect the SlimSAS cable from the adapter to your desired Icy Dock mobile rack or storage enclosure. Ensure that the system is powered down during installation to prevent electrical damage. The device is designed for plug-and-play operation, though users should verify that their BIOS/UEFI settings are configured to recognize NVMe devices on the specific PCIe lane being utilized.

What to consider before purchase

• Verify that your motherboard has an available M.2 slot that supports PCIe NVMe protocol.
• Ensure your storage enclosure or mobile rack is compatible with SlimSAS 4i interfaces.
• Check the physical clearance within your chassis to accommodate the adapter and cable routing.

For optimal performance and signal stability, always use high-quality SlimSAS cables and ensure the adapter is firmly seated in the M.2 slot. Regularly check for firmware updates for your NVMe SSDs to maintain full compatibility with the PCIe 4.0 interface.
