Two-bay 5.25" mobile rack

The ICY DOCK MB322SP-B converts a single 5.25" bay into two hot-swap slots for 2.5" SATA or SAS drives between 7 mm and 9.5 mm thick. A third opening accepts one 3.5" drive or device without a backplane. The tray uses a tool-less design with optional screw holes for extra security.

Replaces fixed 3.5" cages

Builders who currently mount 2.5" drives in 3.5" adapters gain direct front access and hot-swap capability without opening the case. The upgrade is worthwhile when drive changes are frequent or when a 3.5" peripheral such as a card reader must share the same bay.

Fits standard 5.25" bays

The unit connects through two 7-pin SATA host ports and a single 15-pin SATA power connector. A detachable dust cover seals the 3.5" opening when unused. Blue activity LEDs on each 2.5" slot show drive status. Metal housing and reinforced latches handle repeated insertions.

Questions about this item

Will this 5.25" cage fit a standard 5.25" bay in my case?

Yes, the unit is designed for any standard 5.25" device bay and occupies a single bay slot.

How do I install 2.5" drives without tools, and what step is often missed?

Slide each drive into an ExpressTray Mini until the SATA connectors engage fully; the optional bottom tray screws are often skipped but add stability.

Does the detachable dust cover need cleaning or replacement over time?

The cover is a passive plastic piece; wipe it with a dry cloth if dust builds up, but it has no moving parts that wear out.
