Product Information
Full details
The Icy Dock MB994SP-4S is designed for users needing to maximize storage in limited space, such as in servers, workstations, or compact systems. Its key benefit is fitting four 2.5" SATA or SAS HDDs/SSDs into a single 5.25" bay, enabling high-performance RAID applications. A potential caveat is that it requires an available 5.25" bay, which is becoming less common in modern small form factor PCs.

FAQs
Can I use SAS drives with this cage?
Yes, the MB994SP-4S supports both 2.5" SATA and SAS drives.
What is the maximum drive height supported?
The cage supports 2.5" drives with a height of up to 15mm.
Does this require specific drivers?
No, the MB994SP-4S functions as a standard SATA backplane and does not require special drivers. It relies on your motherboard's native SATA controller and operating system support.
How many 5.25" bays does it occupy?
It occupies a single standard 5.25" external drive bay.
What is the data transfer rate support?
It supports SATA 6Gb/s data transfer rates.
Are the EZ Slide Mini Trays compatible with other Icy Dock products?
While designed for this specific model, the EZ Slide Mini Trays are generally compatible with other Icy Dock products that use the same tray design.
How do I know if a drive has failed?
Each drive bay has an LED indicator on the front. Typically, a solid green light indicates power and a flashing red or off light might indicate a drive issue or lack of power/data connection, depending on system configuration.
Troubleshooting
Drives not recognized by the system
Verify that both SATA data cables and 4-pin power connectors are securely connected. Ensure the drives themselves are properly seated in the trays and that the drives are compatible (SATA/SAS, 5-15mm height). Check BIOS/UEFI settings to ensure SATA ports are enabled.
Intermittent drive disconnects
Check for loose SATA data or power connections. Ensure the 4-pin power connectors are firmly seated. Excessive vibration might also cause issues; ensure the cage is securely mounted. Try swapping drive trays or ports.
Overheating drives
Ensure all ventilation slots are clear of obstructions. Confirm the cooling fans are spinning; clean them if necessary. If using high-performance SSDs or HDDs in a high-ambient temperature environment, consider adding system fans to improve overall airflow.
Loud fan noise
The 40mm fans are designed for performance and can be audible. If the noise is excessive or grinding, one or both fans may need cleaning or replacement.
