4 x 2.5" to 5.25" Hot-Swap Cage

The ICY DOCK MB324SP-B fits four 2.5-inch SATA or SAS drives into one 5.25-inch half-height bay. It uses a removable ExpressTray system for tool-less installation and provides hot-swap capability for quick drive changes. A 40 mm fan with high, low and auto speed settings delivers active cooling. The unit connects via four 7-pin SATA data ports and a single 15-pin SATA power connector.

Suits builders adding dense SATA or SAS storage

This cage serves system builders who want up to four 2.5-inch drives in a single optical bay with hot-swap convenience. It supports 7 mm, 9.5 mm and 12.5 mm drive heights and works with SATA 6 Gb/s or single-channel SAS hosts. Buyers whose chassis have no 5.25-inch bay cannot install it. Users needing more than four drives or a different bay form factor must choose another solution.

Single 15-pin SATA power for four drives

The backplane draws all power for four drives through one 15-pin SATA connector, so the power supply must provide that lead. Four separate 7-pin SATA data cables are required to reach the host controller. Verify that your board or HBA has four free SATA ports and a spare 15-pin power plug before purchase.

Questions about this item

Does my motherboard need four free SATA ports and a SATA power connector to use all four bays?

Yes, the unit connects through four 7-pin SATA data ports and a single 15-pin SATA power plug, so each drive needs its own data cable and the cage draws power from one SATA power lead.

Can I keep my older 3 Gbps SATA SSDs in this cage alongside newer 6 Gbps drives?

The backplane supports SATA I, II and III signalling up to 6 Gbps, so legacy 3 Gbps drives will operate at their native speed while newer drives run at 6 Gbps on the same four ports.

How do I confirm the fan is actually cooling the drives after I build the system?

Set the jumper to HIGH, LOW or AUTO; in AUTO mode the 40 mm fan speeds up when drive temperature rises, and you can verify airflow by feeling exhaust at the rear or monitoring drive temperatures in your OS.
