iStarUSA BPU-340HD Drive Enclosure for 5.25" - Serial ATA/600 Host Interface Internal - Black

Discover a premium storage upgrade with the iStarUSA BPU-340HD, a compact, high-performance drive enclosure that makes the most of your 5.25" bays. Built around a robust aluminum chassis with a heat-sinking design, this enclosure enables you to convert multiple large 5.25" bays into a flexible hot-swap rack for up to four HDDs or SSDs (3.5" or 2.5"). With 12Gb/s SATA support, accessible LED indicators for power, cooling, and temperature, and a stylish, durable finish, the BPU-340HD is ideal for media servers, backups, workstation accelerators, and small-scale storage arrays. Whether you’re upgrading an existing build or constructing a compact, RAID-ready storage solution, this enclosure delivers reliability, expansion flexibility, and a sleek industrial look that complements any chassis.

• Flexible drive configuration and hot-swap capability: The iStarUSA BPU-340HD turns 3x 5.25" bays into a versatile backplane that can accommodate up to four drives (4x 3.5" or 2.5" HDD/SSD). Designed for hot-swapping, it allows you to swap drives without powering down your system, minimizing downtime during maintenance or upgrades. The backplane supports 12Gb/s SATA interfaces, delivering high-speed data transfers suitable for demanding workloads and real-time backups. This combination makes it a practical centerpiece for multimedia libraries, surveillance storage, or enterprise-style backups in a compact chassis footprint.
• Premium aluminum chassis with heat-dissipation design: The BPU-340HD features an all-aluminum construction with conductive grooves and a dedicated heat-sink body, optimizing airflow and thermal performance under load. A stylish black finish and a sturdy front-end handle provide durability and a professional aesthetic while the heat-dissipation design helps maintain drive performance and longevity even when the system runs at peak demand. LED indicators for power, fan status, and high temperature alert provide quick at-a-glance health monitoring that helps you catch potential issues before they affect data integrity.
• RAID-ready configuration with external controller support: This enclosure is built to be integrated into RAID workflows, but it requires an additional RAID controller to configure and manage RAID levels. The unit does not include a built-in RAID controller, but it is compatible with external controllers that support backplane-based storage. This setup gives you the flexibility to choose your preferred RAID level and management software while leveraging the high-density, hot-swap backplane for reliable disk operation and easy drive replacement. It is an ideal solution for those who need scalable storage without sacrificing the benefits of a compact, low-profile enclosure.
• Low-noise, high-clarity operation with robust connectivity: With SATA/600 (SATA III) compatibility, the BPU-340HD delivers solid bandwidth for modern HDDs and SSDs, ensuring fast sequential reads and writes where needed. Its integrated cooling and LED indicators help minimize thermal throttling and keep you informed about system health. The enclosure’s internal design emphasizes reliable power delivery and stable operation, making it suitable for long-running backup jobs, media streaming, and server-class workloads in compact environments.
• Easy integration and chassis compatibility: Designed for seamless installation into standard 5.25" bays, the BPU-340HD includes the necessary mounting options to fit in most desktop or small-server chassis. It supports a variety of drive formats (2.5" and 3.5" drives) and works with common power supplies and SATA backplanes. The combination of front access, hot-swap capability, and clear LED indicators reduces maintenance time and simplifies drive replacement, making it an attractive upgrade for both home enthusiasts and IT professionals seeking a durable, scalable storage solution.

How to install iStarUSA BPU-340HD

• Power down your system and locate an available 5.25" bay in your desktop or server chassis.
• Mount the BPU-340HD into the 5.25" bay using the included screws or mounting hardware, ensuring a secure fit and proper alignment with the backplane connectors.
• Connect the SATA data cable from your motherboard or RAID controller to the backplane’s SATA interface, and attach the power cable to the drive backplane power connector. Verify all connections are snug.
• Insert your 3.5" or 2.5" drives into the drive sleds and slide the sleds into the hot-swap bays until they click into place. Confirm that each drive is properly seated and recognized by the backplane.
• If you plan to use RAID, install and configure a compatible external RAID controller in your system, then boot into the controller’s BIOS/management software to set up your RAID array across the backplane drives.
• Power on the system and observe the LED indicators for power, fan activity, and drive health. If any drive fails to initialize, power down and reseat the drive or consult your RAID controller’s management tool for diagnostics.
• Install any required drivers or management software for the RAID controller and monitor drive health, temperatures, and performance through your preferred operating system or server management tools.
