ToughArmor 4-Drive 5.25" Bay Converter

The ICY DOCK MB994SP-4S fits four 2.5" SATA or SAS hard drives and solid-state drives into a single 5.25" front bay. Its full-metal chassis and included dual 40 mm fans provide structural rigidity and active cooling for sustained workloads. Each tray features an individual status LED for immediate drive-health visibility.

Suited for Multi-Drive Arrays Not Single-Drive

This unit targets builders who need four hot-swappable bays in one 5.25" slot such as media servers medical systems or all-in-one workstations. Buyers who only need to install one 2.5" drive or who lack a spare 5.25" bay should consider simpler bracket solutions. The tray height limit of 15 mm also excludes thicker enterprise drives.

Dual-Protocol SATA and SAS 6 Gbps Backplane

The backplane carries four independent 7-pin SATA connectors and supports both SATA 6 Gbps and SAS 2.0 signalling including dual-channel SAS operation. Drive throughput scales with the installed device up to 6 Gbps per port. Compatibility is limited to drives using the SATA or SAS interface.

Questions about this item

How do I install the MB994SP-4S into a 5.25" bay and connect the four drives?

Slide the unit into a single 5.25" device bay, secure it with screws, insert up to four 2.5" SAS or SATA drives into the EZ Slide Mini Trays, then connect each drive to the backplane via the four 7-pin SATA host cables.

What maintenance will the MB994SP-4S require over time?

The dual 40mm cooling fans should be cleaned periodically to maintain airflow; the full metal trays and backplane have no user-serviceable parts, so drive swaps are the only routine action.

What limit appears first during sustained heavy use of the MB994SP-4S?

Each drive is capped at the SATA 6Gb/s interface speed, so sustained throughput cannot exceed that ceiling regardless of the individual SSD or HDD performance.
