Dual 2.5" SATA/SAS in a 3.5" bay

The ICY DOCK MB492SKL-B converts a single 3.5" front bay into two removable slots for 2.5" SATA or SAS drives. It targets industrial PCs, surveillance recorders and embedded systems where physical security and hot-swap access matter. The full-metal chassis and keyed lock deter unauthorised removal. A thumb screw adds a second mechanical restraint. ||

Thermals noise and power

The unit has no fan or active cooling; it relies on case airflow passing through the open tray design. Metal construction conducts heat away from the drives without adding acoustic noise. Power draw is limited to the two installed drives themselves; the backplane adds no measurable overhead. ||

Build integration needs

Installation requires a standard 3.5" front device bay and two 7-pin SATA host cables connected to the motherboard or controller. Each drive tray accepts 7 mm to 9.5 mm heights and locks via key or thumb screw. The 22-pin SATA/SAS device connectors support single-channel SAS and SATA I/II/III. No extra brackets or adapters are included.

Questions about this item

How do I install the MB492SKL-B into a 3.5" front bay and what step is often missed?

Slide the unit into the bay, secure it with the thumb screws on the front bezel, then insert each 2.5" drive into its tray and lock it with the metal key lock — the key lock step is frequently skipped, leaving drives unsecured.

What maintenance or replacement will the MB492SKL-B need over time?

The removable EX-Secure Micro Trays and the metal key lock mechanism are the only serviceable parts; trays can be swapped if damaged and lock cylinders can be re-keyed, while the full metal backplane itself requires no routine maintenance.

What limit appears first during sustained heavy I/O on the MB492SKL-B?

The dual 22-pin SATA device connectors and dual 7-pin SATA host links cap each drive at 6 Gbps, so the interface bandwidth is the first bottleneck under continuous high-throughput workloads.
