RAID controller Areca ARC-1886-4N8I with 4x M.2, 8-port, Tri-Mode PCIe 4.0 x8

Areca ARC-1886-4N8I is a RAID controller designed for high-performance storage systems. The card features four M.2 device connectors and eight ports arranged in a Tri-Mode configuration, enabling mixed NVMe and SATA/SAS device support through a single PCIe 4.0 x8 interface. Intended for use in servers and workstations, the controller offers flexible RAID management and aims to increase I/O throughput for data‑intensive applications.

Advantages

The ARC-1886-4N8I consolidates multiple storage protocols on one expansion card, reducing the need for separate NVMe and SAS/SATA adapters. With a PCIe 4.0 x8 host interface, the controller supports higher bandwidth compared with previous-generation PCIe standards. The presence of four M.2 connectors on-board allows direct attachment of NVMe SSDs, while the eight Tri-Mode ports provide flexibility to connect external or internal SATA/SAS or NVMe devices. RAID management features provide options for configuring redundancy, performance, and capacity according to workload requirements.

Suitable for

• Servers and workstations handling mixed NVMe and SATA/SAS storage
• Database and virtualization hosts requiring increased I/O throughput
• Backup and archive systems needing flexible RAID configurations
• High-performance compute nodes with multiple M.2 SSDs

Key specifications

• Interface: PCIe 4.0 x8 host connection
• On-board device connectors: 4 × M.2 slots for NVMe devices
• Ports: 8 Tri-Mode ports supporting NVMe and SATA/SAS devices
• Form factor: standard PCIe expansion card
• Target systems: servers and workstations

How to use

Install the ARC-1886-4N8I into an available PCIe 4.0 x8 (or compatible) slot on the host system following standard server or workstation hardware procedures. Attach M.2 NVMe SSDs to the on-board M.2 connectors and connect external or internal drives to the Tri-Mode ports using appropriate cables or backplanes. Configure RAID levels and device settings using the controller's management utility or firmware interface, selecting RAID modes that match your requirements for redundancy, performance, and capacity.

Usage recommendations

Ensure the host system BIOS and operating system include drivers and firmware compatible with the RAID controller. For optimal performance, use PCIe 4.0-capable slots and NVMe devices that meet the desired throughput characteristics. When mixing device types on Tri-Mode ports, plan RAID layouts and testing to confirm expected behavior under your specific workload.
