The FP55 is a new generation 5.25-3.5" drive bracket that can accommodate two additional 2.5" hard disk drives or SSD (9.5mm thick) in addition to a single 3.5" device or drive. The front panel is finished with an aluminum hairline and comes in two color choices (black and silver) to match most cases on the market. The FP55 also features two pairs of mounting holes that allow you to choose whether you want to display the aluminum bezel or hide it under your existing drive bay cover. If you need extra drive space and have room in your 5.25" drive bay, the FP55 is a great choice.
