Raidon Technology, Inc. announces the SR4-B32A a 4-bay hardware RAID enclosure designed for desktops and workstations that rely on standard USB‑A ports.

It provides a practical upgrade path for legacy systems, including a USB‑C to USB‑A cable for simple plug‑and‑play deployment and support for up to 10Gb/s transfer speeds on compatible USB 3.2 Gen 2 USB‑A hosts.

A dedicated hardware RAID controller supports RAID-5 for single‑drive fault tolerance, as well as RAID-0, JBOD, and BIG for performance‑oriented or capacity‑focused workflows. With a 150W internal power supply, active cooling, and hot‑swappable lockable trays, the SR4‑B32A is engineered for reliable operation in backup, media, research, and other data‑intensive environments.

Features:

Broad USB‑A Compatibility

Designed for desktops and workstations with standard USB‑A ports. Ships with a USB‑C to USB‑A cable and supports up to 10Gb/s when connected to compatible USB 3.2 Gen 2 USB‑A hosts.

Built-in Hardware RAID

Supports RAID-0, RAID-5, JBOD, and BIG. In RAID-5 mode, the system maintains data availability during a single‑drive failure and begins rebuilding the array once a compatible replacement drive is installed.

Professional, Service‑Ready Design
Supports 4×3.5″ or 2.5″ SATA 3 HDDs or SSDs. Hot‑swappable, lockable trays simplify maintenance and improve physical security. A 150W internal power supply ensures stable, continuous operation.

Status Monitoring and Active Cooling

Front-panel LEDs display power, drive activity, failure alerts, and RAID rebuild progress (25/50/75/100%). Includes a buzzer with mute switch, an adjustable 80mm rear fan, and hardware RAID controls with optional Windows GUI monitoring.

Cross-Platform and Mobile Workflow Support

Plug‑and‑play compatible with Windows, macOS, and Linux. Also supports Easy Data Vault backup for USB‑C iPhone and iPad models when using a USB‑C to USB‑C cable.
