Drive Bay Converter

The iStarUSA BPU-350-Red fits three standard 5.25-inch drive bays and converts them into five hot-swap trays for 3.5-inch drives. An all-aluminium frame with conductive dissipation grooves and a single 80 mm fan provides airflow across the installed disks. Five SATA cables are included for immediate connection.

Suits RAID Builds, Not Single-Drive Upgrades

This cage targets administrators who need RAID 0, 1 or 5 across multiple disks in a server chassis. Builders who only want to add one or two drives without a RAID array should look at simpler mounting brackets instead. The unit also requires three adjacent 5.25-inch bays, so compact cases without that space cannot accommodate it.

SATA 2.0 Interface

The backplane connects each tray through a SATA 2.0 interface, which sets the maximum link speed for every installed drive. If the host controller or the drives themselves operate at a newer SATA revision, they will fall back to this 2.0 rate. Verify that the system can accept this limitation before purchase.

Questions about this item

How do I verify the backplane is operating correctly after installation?

Check the power, fan and high-temperature LED indicators on the front panel; they confirm power delivery, the 80 mm fan is spinning and drive temperatures are within limits.

Which cables and accessories are included with the BPU-350-Red and what must be purchased separately?

Five SATA cables are included for the five hot-swap bays; drives, a SATA host controller or motherboard ports and mounting screws for the 5.25-inch bays are not supplied.

The unit fits three 5.25-inch bays and holds five 3.5-inch drives — which capacity should I choose for my server?

This single model provides five 3.5-inch SATA 2.0 hot-swap slots in a three-bay 5.25-inch form factor; select it when you need exactly five drive bays in that space.
