Note: To utilize an M.2, U.2, or U.3 NVMe SSD in a PCIe 16x or 8x slot, the motherboard or add-on card must support PCIe Bifurcation. This mode divides PCIe lanes into specific configurations like x4, x4, x4, x4 for a 16x slot or x4, x4 for an 8x slot, ensuring the SSD can be read by the system. For compatible hardware, please refer to the FAQ section. If your hardware is not listed there, please contact us for assistance.

The ToughArmor MB842MP-B turns a PCIe 8x or 16x expansion slot into a dual removable M.2 NVMe drive bays, allowing you to swap the M.2 NVMe SSDs without needing to open the computer case. 

Innovative Removable M.2 NVMe SSD Enclosure

A typical M.2 drive is installed on a motherboard or a riser card and is secured by a small screw. Additionally, the physical installation process is very troublesome and time-consuming. The ToughArmor MB842MP-B’s removable drive tray design utilizes the PCI express slot to make the M.2 SSD installation and removal process completely hassle-free.

State of the Art Tool-less M.2 Drive Installation

The tool-less M.2 NVMe SSD installation design takes less than five seconds to complete, saving you the hassle of dealing with tiny easy-to-lose screws.

The patent-pending adjustable M.2 locker secures the M.2 NVMe SSD (2230, 2243, 2260, 2280, 22110) onto the drive tray by sliding the M.2 locker towards the SSD to lock the M.2 SSD in place.

Optimal Cooling Efficiency

The specialized slim M.2 drive tray is made of thick aluminum and acts as a heatsink to dissipate heat generated by the M.2 NVMe SSD.

The included thermal pad fills the gap between the contact surface and transfers heat away from M.2 NVMe SSD to the larger aluminum surface, allowing airflow to move the heat away quickly.

EMI Grounding Technology 

Grounding your M.2 NVMe SSD is critical, especially during frequent drive swaps due to static shocks. Our adjustable M.2 locker will clip into the SSD screw hole and ground the drive throughout the tray and the enclosure.

Maximum Compatibility 

The ToughArmor MB842MP-B is designed for the PCIe slot and is compatible with PCIe 3.0/4.0 x8 and x16 slots.

Note: PCIe Bifurcation mode (x4, x4, x4, x4 for PCIe 16x slot or x4, x4 for PCIe 8x slot) is required to access both M.2 NVMe SSD 

Superior PCIe 4.0 Performance 

The advantage of utilizing the PCIe 3.0/4.0 interface is that it provides power and data through a single PCIe slot, reducing the system’s cable clutter. In addition, the blazing-fast 64Gbps transfer speed is 10x faster than SATA III, making it an ideal solution for data-intensive applications such as machine learning, cloud computing, data mining, or even image processing.

Rugged Protection for the Harshest Environments 

The ToughArmor MB842MP-B is equipped with solid plastic, metal housing, and full metal drive trays to ensure a long product life and comes with a 5-year warranty.

Packed with Features 

The ToughArmor MB842MP-B is built with drive activity LED indicators on each drive tray to show the drive power and activities. The LED will automatically power off when no drive is detected to save energy.

The optional 2-pin HDD activity signal output (cable is not included) allows you to transfer the drive activity signal to the computer case or LED panel and provide an alternative view at the desired location.

Wide Range of Compatibility 

The specially designed MB840TP-B removable drive tray effortlessly enables seamless interchangeability across various models.
