Product IntroductionThe ToughArmor MB720M2K-B is the world’s first quad M.2 NVMe ruggedized removable enclosure. With our enclosure, your NVMe SSD no longer requires to be installed on to the motherboard or even a riser card which is typically held on with a tiny screw. Now it could be installed and accessed from the comfort of the frontal bay of the computer. In addition, it comes with our patent-pending M.2 adjustable drive locker which can easily place your drive without any tools or screws.
The MB720M2K-B is designed to house up to 4x M.2 PCIe NVMe SSD, supporting blazing fast PCIe x4 transfer speed up to 64Gbps via MiniSAS HD (SFF-8643). Our specialized drive tray accepts all standard M.2 drives length from 30mm to 110mm (2230, 2242, 2260, 2280, & 22110). As M.2 drives are notorious for reach high temperatures, each drive tray is equipped with a high efficiency aluminum heat sink to ensure your drives remains within optimal temperatures even under heavy load. As it is part of the ToughArmor Series, the enclosure and trays are made of metal to ensure the maximum protection against your drives and with an included barrel key lock, it prevents any unauthorized physical access.
World’s First Quad M.2 NVMe Removable SSD Mobile RackA typical M.2 NVMe is installed on the motherboard or even a riser card which is often secured by a tiny screw. With this method, it can be a hassle and a time-consuming process to install or remove the drive physically. However, with the ToughArmor MB720M2K-B, your drives are brought to the front of the computer case, making M.2 drive installation and removal a more straightforward and efficient process.
DemonstrationWhen using the ToughArmor MB720M2K-B, the user can simply place their M.2 NVMe SSD in the drive tray, adjust the drive locker to the correct length per M.2 drive size and be set to go. With this method, it will take users a few seconds per drive tray to install, avoid the hassle of dealing with tools and screws while being more efficient and innovative way to installing M.2 drives.
Full Drive Length SupportThe 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 TechnologyAs little do people know, grounding your drive is very important through many swaps; to ensure your drive and most importantly your drives are always safe. Without grounding, when swapping drives, there is a high possibility that there may be static shocks which can damage your drive and lose your data. With our innovative adjustable M.2 locker, it grounds your drive automatically once your M.2 locker clips into the SSD screw hole. The drive will be constantly grounded throughout the tray and housing of the enclosure. The grounded connector design protects your drives from static electrical surge, ensuring your data is always safe during drive swapping.
Superior PerformanceTo fully use the speeds of NVMe, each drive will use its’ own MiniSAS HD (SFF-8643) connector, maximizing the potential transfer bandwidth rate of 64Gbps in each drive bay which is over 10 times faster than previous SATA standard. This makes an ideal solution for data intensive application such as real-time servers, high performance PCs, deep-learning machines, and 4K / 8K / 3D media workstations.
ToughArmor ProtectionEnsuring the enclosure can be relied upon for many years, the ToughArmor MB720M2K-B 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. Because of the high build quality, it can be used in various enterprise systems including the military and law enforcement industries along with manufacturing conditions such as embedded control and factory automation systems.
Maximum Cooling PerformanceAs M.2 NVMe SSD are notorious for reaching high temperature, it is important to keep it cooled at all times or it may result in performance degradation and transfer speed throttling. As we understand this may be concerning to some, on each drive tray it comes equipped a extra-large high efficiency aluminum heatsinked. Additionally, it comes with thermal pads included to ensure the extra excessive heat is dispersed throughout the entire heatsink.
Integrated Aluminum Heatsink Cover
Working together with the dual 40mm ball-bearing cooling fan, the heat is further dispersed through the intelligently place ventilation holes throughout the entire enclosure. Each fan has three fan settings: high, low, and off. The user can manually select the proper cooling option to keep the drives at optimal operating temperatures, even under heavy load.
Packed with FeaturesAn LED status light built into the tray lets you know your drive is powered up and in use. To save power, the LED is shut off when no drive is installed.
For an additional physical layer of security, the included key-lock can be used to protect against unwanted access and secure drives in particularly rough environment, such as military application and in-vehicle PCs.

How can I troubleshoot this issue?
A: Please first confirm the compatibility of your hardware, and make sure that the drive, drive enclosure, cable, and host interfaces are compatible. Try connecting the drive directly to the host to see if the system can detect the drive. If it still doesn't detect it, this can rule out issues with the drive enclosure. You can also try connecting the drive enclosure with different drives, cables, or systems to see if the issue can be resolved. If the system still can't detect it, here are some possible issues:
• Insufficient PCIe lanes in the system: Whether you're connecting the drive enclosure to the motherboard or add-on card, It is important to note that the number of available PCIe lanes is limited. This includes understanding the number of lanes provided by the CPU and chipset, as well as their allocation method. Failure to do so may result slower transfer speeds, unstable connections, or even the inability to detect the drive. • Incompatible interface protocols: It is crucial to verify whether the Mini-SAS HD, OCuLink, or SlimSAS interface on the motherboard or add-on card is capable of supporting NVMe. • Incompatible interface pinout standard: Prior to connecting the drive enclosure to the Mini-SAS HD, OCuLink, or SlimSAS port on the motherboard or add-on card, please verify that the port utilizes the same pinout standard as the port on our drive enclosure. To check the pinout standard of our drive enclosure, you can refer to the specification table on our product page, where it specifies whether the pinout standard is Legacy or SFF-9402 1.1. • Excessive length of the connecting cable: To ensure optimal performance, it is advised to use a connecting cable that is no longer than 50cm. Using longer cables can lead to excessive signal loss, resulting in slower transfer speeds, unstable connections, or even the inability to detect the drive. Additionally, we recommend using the same interface connector for both the device and the host to prevent any potential compatibility issues. Q: I'm using Intel/Broadcom Tri-Mode HBA and RAID cards with the MB720M2K-B, but the drives do not show up in my system?
A: The issue is caused by RAID card manufacturers using a different pinout for Tri-Mode cards than is typically used for U.2 connections. When using these cards with U.2 NVMe drives and cables, a U.2 enabler cable must be used for compatibility, which reverts the pinout back to standard U.2 specifications. For more information, please click here.
Q: The system does not detect the M.2 SSD I installed in the ICY DOCK enclosure. What should I do?
A: Since the M.2 SSD is not designed for hot-swapping or hot-plug, please make sure you power off the device/system before inserting or removing an M.2 SSD. If the system is still unable to detect the drive, follow the steps below to scan for new hardware manually:
If you are unable to detect the drive after performing the manual refresh, your system might not support hot-plug functions. We suggest you check with the motherboard/add-on card manufacturer to see if it supports the NVMe hot-plug function.
Windows 11 / Windows 10 / Windows 8 – In the search box on the taskbar, type device manager, and click it from the menu. Once the device manager window pops up, right-click on the disk drive icon, and click scan for hardware changes.

Q: The mounting screws for the device seem to be too short to secure the device onto my system, what should I do?
A: The included M3*2.5L screws fit most metal sheets of the computer cases with 0.8~1mm thickness. For cases that have a wider 5.25" bay, make sure you place the device in the center to tighten the screw holes on both sides. Please contact us at tech@icydock.com if you have a problem securing the drive enclosure onto the drive bay.
Q: Is the ICY DOCK NVMe enclosure supporting the PCIe 4.0 standard?
A: Yes, all ICY DOCK NVMe enclosures support the PCIe 4.0x4 standard, with up to 64Gbps transfer rates.
Q: Can I replace the cooling fan attached to the device? Will doing that void the warranty?
A: The cooling fan we used has been thoroughly tested with the drive enclosure to ensure it functions properly and supports the fan speed control (for select models). Therefore, we suggest our customers keep the original fan for the best result. However, we understand the stock fan may not be suitable for all the applications, so we elected to honor the warranty when 3rd party fan is using. The warranty may void if the 3rd party fan causes electrical damage to the device, though.
Q: Which specification should I check before buying the 3rd party cooling fan?

(without test, use it at your own risk)Q: I'm having the difficulties closing the lid of the drive tray and unable to insert the drive tray all the way to the drive enclosure after placing the M.2 SSD onto the drive tray.
A: Make sure to lock the M.2 SSD with the adjustable M.2 locker. The tray lid will not close properly if the M.2 locker is not fully secured. If you are having difficulty secure the M.2 locker or close the cover, the M.2 SSD you are using may not follow the standard M.2 SSD thickness, which is less than 1.5mm height for each side with a total height that does not exceed 3.8mm. Using the M.2 SSD with non-standard thickness will cause improper tension on the M.2 locker and tray lid and make the M.2 connector misaligned. If you are having issues inserting the drive tray to the enclosure, please stop the operation immediately and check the drive thickness to ensure it follows the standard M.2 SSD thickness - less than 1.5mm height for each side and less than 3.8mm for total height.
Note: Some M.2 SSD uses a metal heat dissipation sticker that causes each side's thickness more than the 1.5mm. Remove the sticker will solve the problem, but do it at your own risk (might void the warranty of SSD)
ICY DOCK enclosure is design to be compatible with M.2 SSD that has standard thickness. We highly recommend checking the drive thickness before purchase, and please refer to the incompatible M.2 SSD list below for further information:
