Description

Rear drive cage

A rear cage creates extra drive bays at the back of the chassis, usually in place of one of the PCIe risers.

It is used to add boot drives or cache drives without taking front bays.

The chassis's maximum number of drives increases and the front bays stay available for data.

This text is the general explanation of this category of part (not a claim about one specific model).
