ICY DOCK EXLink MB408A4 SlimSAS 4i (SFF-8654) to PCIe 4.0 x4 Adapter Card with Redriver

The ICY DOCK EXLink MB408A4 is a high-performance SlimSAS 4i (SFF-8654) to PCIe 4.0 x4 adapter card designed to connect NVMe SSDs to a host system via a SlimSAS cable. Featuring an integrated redriver for signal enhancement, this low-profile bracket-less card ensures reliable data transfer at speeds up to 64 Gbps. It is backward compatible with PCIe 3.0 and requires no driver installation for plug-and-play operation. Ideal for servers, workstations, HPC, and data storage applications.

Advantages

This adapter card enables seamless integration of SlimSAS-based NVMe drives into PCIe slots, offering high bandwidth and low latency. The built-in redriver compensates for signal degradation over longer cables, ensuring stable performance. Its bus-powered design eliminates the need for external power, and the low-profile form factor fits in space-constrained environments.
