Compact four-bay 2.5" hot-swap cage

The BPU-124DE-SS converts a single 5.25" bay into four hot-swappable 2.5" drive slots, supporting both SATA and SAS drives at up to 6.0Gb/s. It is built for servers and workstations that need high-density storage without shutting down to swap drives.

All-aluminium construction with dual 40mm fans

The aluminium chassis acts as a heatsink while two 40mm fans push air front-to-back across the drives. A key lock secures the tray door, and LED indicators show power, drive activity, overheating and fan-failure states at a glance.

Drives from 7 mm to 15 mm thick mount tool-free

The cage accepts any 2.5" SATA or SAS drive within that thickness range, letting you mix capacities and spindle speeds. No extra brackets or cables are included, so builders must provide their own SATA or SAS data and power connections.

Questions about this item

What transfer rate does the SATA/SAS 6.0Gb/s interface actually deliver?

The backplane supports up to 6.0 Gb/s per drive, matching SATA III and SAS 2.0 speeds.

Will this cage fit a standard 5.25" front bay and what drive thickness does it accept?

It mounts in one 5.25" bay and holds four 2.5" drives from 7 mm to 15 mm thick.

How do I install the BPU-124DE-SS and what step is commonly missed?

Slide the unit into the 5.25" bay, secure it with screws, connect SATA/SAS data and power cables, then insert drives; the step often missed is locking the front door with the included key to enable hot-swap safety.
