Basic Parameter Table

Core Product Features

1. Entry‑level PCIe 3.0 internal‑only IT‑mode HBA card powered by SAS3004 controller chip, factory‑flashed with native IT pass‑through firmware, without hardware‑RAID function. It is designed for compact 4‑bay home‑NAS, small‑form‑factor servers and desktop storage systems running ZFS, TrueNAS, Unraid.
2. PCIe 3.0 x8 bus bandwidth, one SFF‑8643 internal port supporting up to 4 internal hard‑disk channels for chassis‑mounted drive bays.
3. Tri‑mode compatibility supports 12G SAS HDD, 6G SATA SSD and U.2 NVMe drives, enabling mixed‑storage deployment of mechanical and solid‑state disks.
4. Fan‑free passive heat‑sink design, zero‑noise operation, stable for 24/7 continuous runtime in compact PC and rack‑mounted server environments.
5. DOM digital diagnostic monitoring; drive health status, link condition and adapter temperature can be checked via the StorCLI command‑line tool for routine maintenance.
6. Hot‑swap‑capable, allowing online hard‑disk replacement without shutting down the host server.
