Three 5.25 bays become five 3.5 slots

This trayless hot-swap rack converts three standard 5.25-inch drive bays into five 3.5-inch SAS or SATA drive positions. It targets server builders and storage administrators who need dense, high-speed local storage in a 12Gb/s environment. The aluminium frame and integrated key lock suit security-conscious deployments.

Slide drives in from the front

Installation is tool-free: drives insert directly into the front openings without trays or screws. The removable fan cover simplifies cleaning or fan replacement. The only common issue is ensuring the backplane SAS/SATA connectors align cleanly during the first few insertions, which settles after initial seating.

Aluminium frame acts as a heatsink

An 80mm fan and the full aluminium construction dissipate heat across all five bays during sustained RAID workloads. Adjustable fan speed lets operators balance airflow against noise. The design supports 14TB drives at continuous 12Gb/s transfer rates without thermal throttling.
