Drive Cage Conversion

The iStarUSA BPN-DE340SS-SILVER converts three 5.25" bays into four 3.5" hot-swap drive bays. It supports SAS I/II and SATA I/II/III hard drives with data transfer rates up to 6.0 Gb/s. An aluminum frame and front bezel provide structural rigidity and assist heat dissipation. A built-in 80mm fan and removable fan cover maintain airflow for continuous operation.

Who This Suits

This cage suits server builders who need high-density 3.5" storage in a standard 5.25" footprint and require hot-swap capability to minimise downtime. The key lock and LED indicators add physical security and at-a-glance status monitoring. It is not for systems limited to 2.5" drive form factors or cases without three adjacent 5.25" openings. Buyers needing more than four drive bays per unit should look at a different solution.

Deciding Specification

The tray-less hot-swap mechanism accepts four 3.5" SAS or SATA drives simultaneously and enables drive changes while the system runs. This single feature determines whether the cage matches a maintenance window that cannot tolerate a shutdown. Confirm the host backplane or controller supports hot-swap for the chosen drive interface before purchase.

Questions about this item

What maximum data rate does the SATA 6.0 Gb/s interface actually deliver to each 3.5″ drive?

The cage passes the SATA 6.0 Gb/s link straight through to every installed 3.5″ drive, so each bay can reach the full 6.0 Gb/s ceiling.

How many 5.25″ bays must be free to mount this four-bay cage?

It occupies exactly three 5.25″ bays and converts them into four 3.5″ hot-swap slots.

Does the tray-less mechanism need any screws or tools when I slide a 3.5″ drive in?

No tools are required — the drive seats directly into the backplane, and the front handle locks it with the integrated key lock.
