    The ToughArmor MB720MK-B V2 is a Ruggedized Removable Quad M.2 PCIe 4.0 NVMe SSD Enclosure design for a 5.25" optical drive bay and supporting up to 64Gbp/s data transfer rates via OCulink (SFF-8612) interface. It simplifies the process of installing or removing M.2 NVMe SSD by using the removable drive trays with tool-less adjustable M.2 drive locker, making it easy to change drives at any time without open the computer case or dealing with drive mounting screws. For best cooling performance, the MB720MK-B V2 is equipped with dual cooling fans in the rear to remove the heat generates by the high-speed PCIe 4.0 SSD. On top of that, each drive tray comes with an extra-large heatsink lid and thermal pad to ensure your SSDs are at optimal temperatures. As part of ICY DOCK's toughest line, the MB720MK-B V2 is made out of full metal construction with metal barrel key locks for maximum protection.

    Superior PCIe 4.0 Performance

    To unlock the full potential of the PCIe 4.0 NVMe SSD, each drive bay uses a dedicated OCulink (SFF-8612) connector to achieve the bandwidth rate of 64Gb/s, which is two times faster than PCIe 3.0 and 10 times faster than SATA standards. This makes it an ideal solution for data-intensive applications such as autonomous driving, mobile automation, real-time forecast, film editing, and military computing.

    Removable Drive Tray Design

    A typical M.2 SSD is installed on the motherboard or adapter card that is often secured by tiny screws and requires opening the computer case to access the drives. With the ToughArmor MB720MK-B V2, your M.2 NVMe SSDs are brought to the 5.25" optical bay of the computer system and lets you change the drives without open up the case, making drive maintenance a more efficient and straightforward process

    Patent-Pending M.2 Drive Locker

    To install the drive, simply place the M.2 PCIe NVMe SSD in the drive tray, adjust the M.2 drive locker to the correct drive length, and you are all set to go. No tools or screws are required.

    Full Drive Length Support

    The M.2 adjustable locker accommodates all standard M.2 PCIe NVMe SSD drives, including 2230 (30mm), 2242 (42mm), 2260 (60mm), 2280 (80mm), and 22110 (110mm), making this drive universal to all M.2 drive length and future-proofing the extra-long M.2 110mm drive.

    EMI Grounding Technology

    Grounding your M.2 SSD is essential as swapping drives without proper grounding may lead to hardware damages due to static shocks. With our innovative EMI Grounding Technology, once the drive clips in the M.2 adjustable locker, the drive will be in a constant grounded state throughout the tray, housing, and computer system to ensures your drives are protected from static electrical surges and safe during swapping.

    ToughArmor Protection

    Ensuring the enclosure can be relied upon for many years, the ToughArmor MB720MK-B V2 is capable of holding up in the harshest environment. It comes equipped with rugged, heavy-duty full-metal protection throughout the entire device and tray, making it perfect for industrial devices that may require a flammability rating. The outstanding build quality is suitable for various enterprise systems such as military and law enforcement industries, in-vehicle computers, and manufacturing conditions such as embedded control and factory automation systems.
