Dual 2.5" SAS/SATA cage with ODD bracket

The ICY DOCK MB732SPO-B fits one external 5.25" bay and accepts two 2.5" SAS or SATA drives up to 15mm height plus one ultra slim or slim optical drive. It connects to the host through two SATA 7-pin cables and includes a Slimline SATA power adapter. Builders adding hot-swap storage while keeping an optical drive use this bracket.

Sustained load behaviour

The all-metal housing and ABS caddies dissipate heat from both drives during long transfers or RAID rebuilds without active cooling. Hot-swap trays allow drive changes while the system runs, so maintenance does not interrupt uptime. The rigid frame keeps connectors aligned through repeated insertion cycles.

Single deciding specification

The unit occupies exactly one 5.25" bay and supports three devices through two SATA host ports, so the second drive shares bandwidth with the first. Buyers who need independent SATA lanes for each drive or who lack a free 5.25" bay cannot use this cage.

Questions about this item

How much heat does the MB732SPO-B add when both 2.5" drives and the slim ODD run continuously?

The all-metal cage and ABS caddies conduct drive heat directly to the 5.25" bay chassis, so temperatures depend on your case airflow rather than on any built-in fan.

Which cables and connectors must my system already provide for the MB732SPO-B to function?

You need two free SATA 7-pin data ports on the motherboard or controller plus one standard SATA 15-pin power lead; a Slimline SATA 6-pin to 15-pin power adapter is included.

Will the MB732SPO-B work with older SATA I or II drives I want to keep using?

Yes, the cage accepts SATA I, II and III drives as well as SAS drives, so legacy 2.5" disks up to 15 mm height install without adapters.
