Build a Seamless Removable NVMe Storage Workflow
The ICY DOCK EXLink MB309A is a high-performance M.2 NVMe to SlimSAS 4i (SFF-8654) PCIe adapter card designed to bridge embedded M.2 SSD slots and professional-grade NVMe removable storage solutions. Engineered to simplify complex system configurations, the MB309A enables system integrators and workstation builders to create a seamless, high-speed, and modular NVMe workflow using ICY DOCK’s mobile racks and cables—no more guesswork around component compatibility or sourcing from multiple vendors.
Instead of pairing your M.2 SSD with fixed internal storage or relying on limited expansion card slots, the MB309A allows you to convert an onboard M.2 PCIe slot into a removable NVMe storage bay by pairing with any of ICY DOCK’s

Redriver & Signal Conditioning for High-Speed NVMe Performance
The EXLink MB309A is equipped with a PCIe Gen 4.0 redriver and 100MHz PCIe clock buffer, designed to maintain signal clarity and stability over long PCB traces and SlimSAS cable runs. Unlike standard adapter cards that often suffer from signal loss or speed throttling when trace or cable distance increases, the MB309A ensures stable PCIe 4.0 transfer rates up to 64Gbps - ideal for high-performance applications requiring full-speed NVMe connectivity.

Additional embedded signal conditioning features include:
Redriver IC ensures clean high-speed signal
100MHz PCIe clock buffer extends trace length
Bus buffer gates support PERST#/WAKE#/CLKREQ# signaling
SMBus repeater for stable device management
Even under intense workloads, these features keep your SSD cool and data safe.

Flexible NVMe Integration, Powered by EXLink
The MB309A is a key part of ICY DOCK’s EXLink ecosystem, designed to simplify the deployment of removable NVMe SSD solutions. Whether you're upgrading a single M.2 slot, building a front-access U.2 configuration, or expanding dual-drive capacity, MB309A works seamlessly with ICY DOCK’s mobile racks and SlimSAS cables to deliver a turnkey setup.
This plug-and-play compatibility removes the guesswork from system design - ensuring your enclosure, cable, and adapter card all work together out of the box. As your NVMe needs grow, the EXLink ecosystem offers scalable options that adapt to your platform with ease.
