PCI-e 3.0 x4 to Mini SAS HD adapter

This PCI-e 3.0 x4 adapter connects a host system to Mini SAS HD SFF-8643 devices. It targets builders adding high-speed storage links to servers or workstations without installing extra drivers. The board uses a four-layer PCB for signal integrity. A bundled SFF-8639 NVMe cable is included for direct drive attachment.

Interface limited to PCI-e 3.0 x4 bandwidth

The adapter operates at PCI-e 3.0 x4 electrical speeds, so connected drives cannot exceed that link width. SFF-8643 version 3.5 compliance ensures mechanical compatibility with current Mini SAS HD cables. No software driver is required for Windows 10, Windows 8, Server 2012 R2 or Linux. Performance scales with the host slot and attached device capabilities.

Suits single-port SAS or NVMe connections

One SFF-8643 plug handles a single four-lane link to a backplane or direct-attached NVMe SSD. Builders needing multiple ports or wider aggregates must add more adapters. The bundled SFF-8639 cable covers NVMe drive cabling up to the adapter's single-port limit.
