Compact 5.25" cage for four 2.5" SATA drives
This cage fits a single 5.25" bay and holds four 2.5" SATA drives up to 12.5 mm thick. It is built for servers or workstations that need hot-swap storage density without using 3.5" bays. RAID 0, 1, 5 or JBOD can be configured at the controller level. The tray-less design lets drives slide straight into the backplane.
SATA 6.0 Gb/s backplane limits throughput
Each drive connects through a SATA 6.0 Gb/s backplane, so the practical ceiling is the SATA III link speed. Four drives share the same bay width, so aggregate bandwidth depends on the host controller and cable routing. The cage itself does not add RAID logic; it only passes the native SATA signals. Drives thicker than 12.5 mm will not fit the slots.
Tool-free install with key-lock security
Drives insert and eject without tools, and the front key lock prevents accidental removal. Blue LEDs show power and per-drive activity at a glance. Common issues are seating drives fully so the SATA connectors engage, and ensuring the host backplane cables are firmly latched. The plastic handle with metal latch survives repeated swaps but can crack if forced.

Questions about this item
Should I choose the single 5.25" bay version or a multi-bay model?
The BPN-124K-SA occupies one 5.25" bay and provides four hot-swap 2.5" SATA trays, so no multi-bay version exists for this model.
What does the 6.0 Gb/s headline rate deliver inside a server?
The backplane supports SATA 6.0 Gb/s per drive; actual throughput depends on the installed drives and the host controller, not the cage itself.
Which SATA standard does the cage use and what does it limit?
It uses SATA I/II/III connectors, capping each bay at the 6.0 Gb/s interface maximum for 2.5" drives between 7 and 12.5 mm thick.
