SSD enclosure Icy Dock ToughArmor MB720M2K-B

The ToughArmor MB720M2K-B is a removable 4-bay M.2 NVMe enclosure designed for front-access installation in a 5.25" bay. It accepts up to four M.2 PCIe NVMe SSDs (lengths 2230–22110) and connects via MiniSAS HD (SFF-8643) to provide up to 32 Gbps per bay. The metal enclosure and trays include an included barrel key lock and individual drive ID labels for easy identification and physical protection.

Advantages

This enclosure enables quick, tool-free installation and hot-swapping of M.2 NVMe SSDs using a patent-pending adjustable M.2 drive locker that secures and grounds each drive. Each tray has an extra-large aluminum heatsink and included thermal pads, while dual 40 mm ball-bearing fans with three speed options improve cooling. Individual MiniSAS HD connectors per drive maximize PCIe x4 bandwidth, and full-metal construction provides rugged protection suitable for demanding environments.

Suitable for

• High-performance workstations and servers requiring fast NVMe storage
• Data-intensive applications: real-time servers, deep learning, 4K/8K and 3D media
• Industrial and mobile systems where drive security and easy swap are needed
• RAID arrays and storage pools that use removable M.2 media

How to use

Place an M.2 NVMe SSD into a drive tray, slide the patent-pending adjustable M.2 locker to match the drive length and allow it to clip into the SSD mounting hole to secure and ground the drive. Insert the loaded tray into the front bay until it locks in place. Connect MiniSAS HD cables from each bay to the host adapter or backplane and attach a compatible 15-pin SATA power cable with a locking latch. Power on the system and select the desired fan speed as needed.

Usage recommendations

For optimal performance, use PCIe x4 NVMe SSDs, ensure proper airflow in the host chassis, and enable an appropriate fan speed under sustained heavy load. Always ground yourself before handling drives and keep drive ID labels attached to maintain correct drive ordering in RAID or storage arrays.
