NasBoost CP8S-12G HBA Card | PCIe to 8x 12Gbps SAS/SATA | Broadcom LSI 3008 | IT Mode | Active Cooled

Unlock enterprise-grade storage expansion with the NasBoost CP8S-12G HBA Card. Built around the proven Broadcom LSI SAS3008 controller, this host bus adapter converts a single PCIe 3.0 X8 slot into 8 independent 12Gbps SAS/SATA ports via 2 x SFF-8643 (Mini-SAS HD) connectors, delivering up to 96Gbps of aggregate bandwidth. Pre-flashed in IT Mode (Initiator Target / pass-through), it presents each connected drive directly to the operating system without any hardware RAID abstraction — the ideal foundation for software-defined storage platforms such as TrueNAS, Unraid, ZFS, Proxmox, and Ceph. The onboard active cooling solution keeps the controller within safe operating temperatures even under sustained 24/7 workloads.

Key Features

• Broadcom LSI SAS3008 Controller: Enterprise-class 12Gbps SAS controller with a mature, widely validated driver stack for maximum reliability and long-term stability.
• Dual SFF-8643 Ports for up to 8 Drives: Two native SFF-8643 (Mini-SAS HD) connectors expand a single PCIe 3.0 X8 slot into up to 8 SAS/SATA drive bays via two breakout cables — each connector carries 4 lanes of 12Gbps, delivering up to 96Gbps aggregate throughput.
• Single-Slot Form Factor: Despite the integrated ball-bearing fan, the card keeps a single-slot profile — it never occupies an extra PCIe slot, making it ideal for compact NAS chassis, ITX motherboards, and multi-card side-by-side installations.
• Custom Long-Life Ball-Bearing Fan + Silver Electroplated Heatsink: A newly designed silver electroplated heatsink paired with a long-life ball-bearing fan directly solves the notorious overheating and drive-drop issues of the SAS3008 chip in ordinary NAS chassis, guaranteeing stable 24/7 operation under sustained heavy load.
• IT Mode (Pass-Through) Pre-Flashed: Ships in pure HBA mode with no hardware RAID layer, exposing every disk directly to the OS — essential for ZFS, Unraid, and TrueNAS software RAID.
• PCIe 3.0 X8 Interface: Fully compatible with PCIe 3.0 X8 and X16 slots, providing direct-to-CPU lane bandwidth without bottlenecks.
• Broad OS Compatibility: Native driver support across Linux, Windows, VMware ESXi, and FreeBSD — no proprietary drivers required.
