4-bay 2.5" SAS drive bay adapter

The ICY DOCK MB994SP-4S installs four 2.5-inch SAS drives into a single 5.25-inch front bay. It suits server and workstation builders who need dense, hot-swappable storage without sacrificing external drive slots.

Thermals noise and power draw in normal use

The all-metal tray conducts heat from each drive directly to the chassis airflow path. No onboard fan means silent operation and zero additional power draw beyond the drives themselves.

How it fits into a build

A single 5.25-inch bay and a backplane or controller with SAS connectors are required. The adapter frees three 3.5-inch internal bays that would otherwise hold individual drive cages.

Questions about this item

How do I install the MB994SP-4S and what step is often missed?

Mount the adapter into a standard 5.25" front bay, secure it with screws, then insert up to four 2.5" SAS drives into the trays. The step often missed is connecting each drive to a SAS backplane or controller with the correct cable orientation.

What maintenance or replacement will the MB994SP-4S need later?

The trays and latch mechanisms are the only moving parts. Over time the plastic ejector clips can wear or snap, so keep spare trays on hand. No fans or filters are present, so no cleaning schedule is required.

What limit appears first when the MB994SP-4S runs under sustained load?

Because the enclosure has no active cooling, drive temperature is the first bottleneck. Extended heavy I/O will raise 2.5" SAS drive temps until thermal throttling engages, limiting sustained throughput.
