Drive-bay converter for dense storage

This hot-swap rack turns three standard 5.25-inch bays into four bays that accept both 2.5-inch and 3.5-inch drives. It is built for server builders who need to pack more disks into a limited chassis without sacrificing hot-swap convenience.

12 Gb/s SAS and SATA interface

The backplane supports SAS I, II and III as well as SATA I, II and III at up to 12 Gb/s per port. That single bandwidth ceiling decides whether your controller and drives can run at their rated speed.

Aluminium chassis with conductive grooves and 80

An aluminium frame and handle act as a heatsink while dissipation grooves spread heat across the metal. A single 80 mm fan with a speed-control switch moves air across all four drives, keeping temperatures stable during continuous RAID rebuilds or streaming workloads.

Questions about this item

What does the 12Gb/s transfer rate mean for my drives in this rack?

It allows each installed SAS or SATA drive to run at its full 12Gb/s link speed, provided your controller and cables also support 12Gb/s.

Which drive interfaces does the backplane actually pass through to the host?

The backplane passes SAS I, II, III and SATA I, II, III signals unchanged; it does not translate protocols or limit the link speed.

How many 5.25-inch bays does this unit occupy in my chassis?

It fits into three standard 5.25-inch front bays and presents four 3.5-inch hot-swap trays behind the bezel.
