Raidon iR5440 — Compact 4-bay 2.5″ SATA Hardware RAID Module

The Raidon iR5440 is a compact 4-bay 2.5-inch SATA hardware RAID module designed to bring RAID 5 protection and high-density storage to systems with a 1U ODD-bay footprint.It enables system integrators to add protected storage, hot-swap serviceability, and system-level monitoring without requiring a RAID card or system redesign.

Supporting RAID 0, RAID 5, BIG, and JBOD, the iR5440 provides flexible configuration options for performance, capacity expansion, or data protection. Its full-metal chassis, hot-swappable trays, active cooling, rebuild-progress LEDs, buzzer alerts, and Windows-based STATUSGUARD GUI monitoring make it suitable for industrial PCs, surveillance systems, edge-computing platforms, compact servers, and professional workstations.Features

• Compact 4-Bay 2.5-Inch SATA Storage Design
  The iR5440 supports four 2.5-inch SATA HDDs or SSDs in a compact 1U ODD form factor, making it suitable for space-limited industrial PCs, embedded systems, edge devices, small servers, and short-depth rackmount platforms.

• Hardware RAID 0, RAID 5, BIG, and JBOD Support
  Multiple RAID modes support performance, protection, or capacity expansion:

RAID 5 can tolerate one drive failure and continue operating while the failed drive is replaced and the array is rebuilt.

• Single SATA Host Connection
  The iR5440 connects to the host system through one SATA III 6.0Gb/s interface. In RAID 0, RAID 5, and BIG modes, the hardware RAID controller manages all four drives and presents the array as a single volume, freeing host SATA ports for other devices and simplifying system integration.

Note: In JBOD mode, the host SATA controller must support Port Multiplier to detect all drives individually.

• Hot-Swappable Full-Metal Drive Trays
  Each bay uses a removable 2.5-inch full-metal tray with a secure locking mechanism. The hot-swap design supports faster drive replacement and easier field maintenance.

• RAID Rebuild and System Status Indicators
  Front-panel LEDs indicate drive activity, drive failure, and RAID rebuild progress. Rebuild progress is displayed at 25%, 50%, 75%, and 100%, allowing technicians to monitor array recovery quickly.

• Raidon STATUSGUARD GUI Monitoring for Windows OS
  Raidon STATUSGUARD GUI software provides RAID status monitoring, device management, drive-health checking, alerts, and event log review through a Windows-based graphical interface

Note: STATUSGUARD GUI is available for Windows OS. Linux systems may use standard OS-level storage tools.

• Thermal and Fan-Failure Alerts
  The iR5440 includes overheat and fan-failure monitoring with LED and buzzer alerts. A buzzer mute switch allows users to silence the alarm after the issue has been acknowledged.

• Full-Metal Chassis with Active Cooling
  The full-metal enclosure improves durability and heat dissipation. A built-in 40 mm low-noise fan supports stable thermal control in compact system environments.

Applications

• Industrial Automation and Control Systems
  Protects logs, control data, and local system records from single-drive failure, helping reduce downtime risk
• Surveillance and Security Systems
  Supports recording continuity during a drive failure with RAID 5 protection and hot-swap serviceability
• Edge Platforms
  Adds protected local storage in compact 1U ODD-bay systems where PCIe RAID cards may not be practical
• Professional Workstations
  Suitable for CAD/CAM, 3D rendering, media production, and scientific workloads, allowing users to configure RAID 0 for maximum performance or RAID 5 for protected storage
• Small Servers and Backup Systems
  Suitable for small servers and local backup systems that require compact RAID storage

Important Usage Notes

• JBOD mode requires a SATA host controller with Port Multiplier support
• RAID 0, RAID 5, and BIG modes present the array as a single volume and do not require Port Multiplier support
• Configure RAID mode before installation
• Drives previously used in a RAID 5 array should be fully erased and re-initialized before reuse
• RAID 5 is not a backup solution. Important data should always be backed up separately
• Use SATA HDDs or SSDs suitable for RAID or continuous-operation workloads
• 2 SATA drives may be supported when used with a Raidon SROCK SATA adapter installed in the drive tray
