iStarUSA Inc. RP-2HDD2535 server accessory 5.25" bay 2x2.5" 1x3.5

Drive bay cage for mixed drive sizes

The iStarUSA RP-2HDD2535 converts a single 5.25 inch bay into space for three drives. It accepts two 2.5 inch HDDs or SSDs and one 3.5 inch HDD at the same time. The metal chassis slides into standard server or workstation fronts. Builders who need to add local storage without sacrificing external bays will find it useful.

Capacity and headroom

The cage holds exactly three drives in a fixed layout. Two 2.5 inch slots sit beside one 3.5 inch slot, so you cannot add a fourth drive later. It works well for a small OS pair plus a larger data drive. Systems that require more than three drives in one bay will need a different solution.

Build quality and daily use

A full metal frame protects the drives and keeps alignment precise during installation. Drives mount with screws for a secure fit that resists vibration in rack environments. The design uses the existing 5.25 inch opening, so no extra case modifications are required. Buyers who want tool-less trays or hot-swap capability will not find those features here.
