5×3.5" SATA hot-swap cage

The ICY DOCK MB155SP-B fits five 3.5" SATA hard drives into three 5.25" device bays. A full-metal backplane and 92mm fan deliver direct airflow across all drives. Each bay uses a 15-pin SATA power connector and a 7-pin SATA data port. Hot-swap trays allow drive changes without powering down the system.

Server builders and dense storage users

This unit suits administrators who need maximum 3.5" density in limited 5.25" space and want hardware hot-swap capability. Builders using 2.5" drives, SAS-only backplanes, or enclosures without 5.25" bays cannot install this cage. Systems requiring tool-less tray ejection or single-drive power control will not find those features here.

6 Gbps SATA backplane speed

The backplane supports SATA I, II and III at up to 6 Gbps per drive. SAS 3.0 single-channel operation up to 12 Gbps is also supported. Drive throughput is limited by the SATA interface and the host controller, not by the cage itself.

Questions about this item

How do I install the MB155SP-B into three 5.25" bays and connect the drives?

Slide the unit into three front-facing 5.25" half-height bays, secure it with screws, attach five SATA data cables to the backplane ports, then plug three 15-pin SATA power connectors into the unit before inserting drives into the EZ-Tray carriers.

What maintenance will the 92mm cooling fan require over time?

The 92mm fan is the only moving part; periodically clean dust from its blades and the metal body vents with compressed air to maintain airflow, and replace the fan if bearing noise appears.

At what transfer rate does the backplane cap sustained throughput?

The SATA 6Gbps backplane limits each drive to 6Gb/sec, so sustained sequential traffic cannot exceed that ceiling even if the drives themselves are faster.
