Overview

Increase internal storage capacity with the RAIDON iT5440, a 4-bay 2.5" SATA JBOD module designed for space-constrained professional and industrial systems. Installed in a single standard 5.25" bay, it supports four independent SATA drives, each connected through its own SATA III 6 Gb/s data path for direct OS-level visibility and flexible drive allocation across backup, archive, media, software RAID, and system storage workflows.

Built with a short-depth full-metal chassis, active cooling, MCU-based fan failure and over-temperature monitoring, front-access serviceability, and hot-swap-ready key-lock trays, the iT5440 provides a practical internal storage expansion solution for workstations, industrial PCs, edge systems, and compact servers.

Features

1. High-Density 4-Bay Storage Expansion

The iT5440 expands internal storage by fitting four 2.5" SATA drives into one standard 5.25" bay, reducing the need for chassis changes or external storage. Its short-depth design is well suited for compact workstations, industrial PCs, edge systems, and space-constrained servers.

2. Four Independent SATA Connections

The iT5440 provides four drives, four SATA connections, and full independent host control. Each drive connects directly to the host through its own SATA III 6 Gb/s data path, with no module-side port multiplication and no shared controller bandwidth inside the enclosure.

3. JBOD Mode for Direct OS-Level Drive Visibility

Operating in JBOD mode, the module exposes each drive directly to the operating system. This allows users to manage each drive independently and assign drives for OS, cache, backup, archive, media, software RAID, or other storage workflows.

4. Hot-Swap Serviceability with Key-Lock Trays

Each bay uses a removable 2.5" drive tray with a key-lock mechanism to help prevent unauthorized drive removal. The trays are designed for hot-swap service; actual hot-swap behavior depends on host SATA controller, BIOS, and OS support. Screw-secured trays help keep drives firmly installed and reduce vibration during operation.

5. MCU-Based Enclosure Monitoring

The iT5440 includes an onboard MCU that monitors enclosure conditions such as fan failure and over-temperature status. When abnormal conditions occur, the system provides LED and audible buzzer alerts to support faster maintenance response. A mute switch allows users to silence the buzzer during service.

6. Full-Metal Chassis with Active Cooling

The full-metal chassis provides structural rigidity and supports passive heat dissipation. The non-overlapping drive layout improves airflow efficiency, while the built-in 40 mm low-noise fan helps maintain stable operating temperatures in compact or enclosed systems.

7. Front-Panel Drive Status Indication

Drive status is shown through front-panel LEDs, allowing users to visually check each drive’s access/activity state directly from the front of the system.

Benefits 

Applications

1. Video Surveillance & NVR

Continuous recording workflows benefit from independent drive access and front-access serviceability. Drives can be organized by camera group, retention period, recording task, or storage tier, while removable trays simplify drive replacement and maintenance.

2. Data Backup & Archiving

JBOD mode supports straightforward backup rotation, off-site drive handling, and long-term archival workflows. Each drive can be managed independently, making the iT5440 suitable for businesses and professionals that need flexible internal backup storage.

3. Media Production & Post-Processing

Editors and content creators can assign SSDs for scratch disks, cache, or active projects, while using HDDs for project archives and media storage. All four drives remain accessible from a single 5.25" workstation bay.

4. Scientific Research & Data Analysis

Researchers and engineers handling large datasets can allocate drives independently for raw data, processed results, analysis workloads, and backup copies. Independent SATA connections help maintain predictable drive behavior across multiple data tasks.

5. Software Development & Virtualization

Developers can isolate virtual machines, containers, build environments, source code repositories, and project backups across separate SSDs or HDDs, helping reduce I/O contention and simplify data organization.

6. Industrial Computing & Edge Systems

The short-depth design, full-metal construction, active cooling, and front-access trays make the iT5440 suitable for industrial PCs, automation systems, edge platforms, and compact systems where space, serviceability, and thermal stability matter.

7. Small Office & Server Storage Expansion

The iT5440 provides a compact way to increase internal storage capacity in workstations, small servers, and office systems without changing the chassis or using additional external storage devices.

Frequently Asked Questions (FAQ)

Q1: What is the RAIDON iT5440 designed for?

A: The RAIDON iT5440 is designed to add four removable 2.5" SATA drive bays into a single standard 5.25" drive bay. It is suitable for compact workstations, industrial PCs, edge systems, small servers, and other systems that require high-density internal storage expansion with front-access serviceability.

Q2: How many drives does the iT5440 support?

A: The iT5440 supports up to four 2.5" SATA HDDs or SSDs. Each drive has its own dedicated SATA data connection to the host system.

Q3: Does the iT5440 support RAID?

A: The iT5440 operates in JBOD mode and does not include onboard RAID. RAID can be configured through the operating system or through a dedicated RAID controller connected to the four SATA data paths.

In simple terms, choose iT5440 when you need four independent drives. Choose iR5440 when you need onboard hardware RAID, especially RAID 5.

Q4: How does the iT5440 provide independent drive access?

A: Each installed drive connects directly to the host through its own SATA III 6 Gb/s data path. This allows the host system to detect, manage, and control all four drives independently.

Q5: What interface and transfer speed does the iT5440 support?

A: The iT5440 supports four SATA III 6 Gb/s data connections, one for each drive. Actual transfer performance depends on the installed HDD or SSD, the host SATA controller, system configuration, and operating environment.

Q6: Is hot-swap supported?

A: The removable trays are designed for hot-swap service. Actual hot-swap behavior depends on the host SATA controller, BIOS, and operating system support.

Q7: How does the alert system work?

A: The iT5440 includes an onboard MCU that monitors enclosure conditions such as fan failure and over-temperature status. When abnormal enclosure conditions occur, the system provides LED and audible buzzer alerts to support faster maintenance response.

Q8: How are drive states shown?

A: Each tray includes front-panel LEDs that indicate drive access/activity status, allowing users to visually check drive operation from the front of the system.

Q9: How are the drives secured?

A: Each removable drive tray includes a key-lock mechanism to help prevent unauthorized drive removal. Drives are also secured with screws to improve installation stability and reduce vibration during operation.

Q10: Will the iT5440 fit in my system?

A: The iT5440 is designed to fit a standard 5.25" external drive bay. Users should also confirm available internal depth, SATA data connections, SATA power availability, and host hot-swap support if hot-swap operation is required.

Q11: What are the key advantages of the iT5440?

A: The iT5440 combines four independent SATA drive connections, JBOD operation, front-access removable trays, key-lock security, MCU-based enclosure monitoring, active cooling, and a full-metal short-depth chassis. It is a practical storage expansion module for systems that require direct drive access, organized internal integration, and service-friendly maintenance.
