Icy Dock MB322SP-B drive mounting frame

The Icy Dock MB322SP-B is a compact 5.25” drive bay panel that converts a single external bay into two hot-swap 2.5” SATA/SAS drive bays (supporting 7mm and 9.5mm heights) plus one 3.5” slot for a hard drive or other 3.5” device. Constructed with a metal housing and reinforced door latches, the MB322SP-B includes a detachable dust cover for the 3.5” slot, soft blue LED activity indicators for each 2.5” bay, and multiple ventilation openings for improved cooling.

Advantages

The MB322SP-B provides space versatility by enabling installation of two 2.5” HDD/SSD units in a single 5.25” bay while retaining an additional 3.5” slot for a hard drive or other 3.5” device. Its ExpressTray Mini offers tool-less installation for 2.5” SATA/SAS drives to simplify swap-in and swap-out operations, and optional bottom tray screw holes are available when extra drive stability is required. The detachable dust cover keeps the system protected from debris when the 3.5” slot is unused, and soft blue LEDs indicate drive activity without being overly bright.

Suitable for

• System builders adding hot-swap 2.5” drives in a 5.25” bay
• Users who need a mix of 2.5” SSD/HDD and a 3.5” device or HDD
• Environments requiring easy drive insertion/removal without tools
• Compact workstation and server builds needing additional storage flexibility

How to use

Install the MB322SP-B into a standard 5.25” device bay and secure it according to your chassis instructions. For 2.5” drives, use the ExpressTray Mini: place the front end (side without connectors) onto the built-in pins so it sits flush, then press the rear end (side with connectors) down until the drive seats fully. To remove a 2.5” drive, pull the rear tab on the tray to release the drive and lift it out. If additional security is needed, fasten the drive with screws using the optional bottom tray screw holes. For the 3.5” slot, either install a 3.5” HDD/device or attach the detachable dust cover when the slot is unused.

Recommendations

For reliable operation, use 2.5” SATA drives of 7mm or 9.5mm height and ensure proper chassis grounding. If using SAS drives, connect to a compatible SAS host. When operating in environments with frequent drive changes, consider using the tray screw holes for added stability and ensure adequate case ventilation to maintain drive temperatures.
