Icy Dock ToughArmor MB852M2PO-B Drive Enclosure for 5.25" PCI Express NVMe, M.2 Internal - Black

$276.95 Regular price

The ToughArmor MB852M2PO-B replaces the legacy slim CD/DVD bay with 2 x high-speed M.2 NVMe SSD. It fits Ultra-Slim 9.5mm optical disk drive (ODD) bay and uses removable M.2 drive trays for effortless drive access and maintenance. It is a perfect storage upgrade solution for customized Industrial-PC, Server Rackmount, and Embedded Systems.

World's First Removable M.2 NVMe SSD Enclosure

The M.2 drive is typically installed on a motherboard or PCIe card and secured by tiny screws. It can be a time-consuming process when installing or removing the drive and makes M.2 SSD not the ideal choice for enterprise applications where easy maintenance with minimum downtime is essential. ToughArmor MB852M2PO-B's swappable M.2 drive trays allow you conveniently access the drives from the frontal Ultra-Slim optical drive bay of your system without opening the computer case.

In order to support M.2 22110 SSD, the length of MB852M2PO-B is longer than the standard Ultra-Slim ODD (159.3mm). Make sure to check the clearance of your Ultra-Slim ODD bay before purchasing.

Effortless Tool-less M.2 Drive Installation

The ToughArmor MB852M2PO-B is designed with a patent-pending M.2 adjustable locker for tool-less drive installation/removal. Simply insert the M.2 SSD (2230, 2242, 2260, 2280, and 22110), move the adjustable M.2 locker until it firmly secures the M.2 SSD and closes the lid. The whole process only takes less than 10 seconds to complete, saving your valuable time and resources.

Superior PCIe 4.0 Performance

To fully utilize the speeds of M.2 NVMe SSD, each drive bay of the MB852M2PO-B uses its' own PCIe Gen 4 OCuLink (SFF-8612) connection and support up to 64Gbps data transfer speed, which is up to 2 times faster than PCIe 3.0 and 10 times faster than SATA interface.

Optimal Cooling Efficiency

The specialized slimline tray is made with thick aluminum and acts as heatsink to dissipate heat generated by the M.2 NVMe SSD through large ventilation opening on both the top and bottom of the device.

The included thermal pad fills the gap between the contact surface and transfers heat away from the M.2 SSD to the larger surface of the metal cover, allowing airflow to dissipate the heat away quickly.

EMI Grounding Technology

Grounding your M.2 SSD is very important through many swaps. Swapping drive without grounding properly may lead to hardware damages due to static shocks. With our innovative EMI Grounding Technology, once the M.2 locker clips into the SSD screw hole, the SSD will be in a grounded state throughout the tray and housing of the enclosure. Once the enclosure installed in the system with four screws on its' side, it will then ground itself throughout your computer system.

With the ToughArmor Series, it is equipped with a ruggedized full-metal chassis and tray to ensure a long product lifespan. An anti-vibration mechanism is built right into the chassis to reduce noise and shield the drive from environmental damage.

LED indication

The MB852M2PO-B is equipped with drive activity LED indicator on the drive tray to show drive power and activity. The LED will be automatically powered off when no drive installed to indicate an empty bay.
