  • Product Introduction
    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.
  • Maximizing Cooling Performance
    Considering M.2 NVMe SSD is notorious for generating high temperatures, the drives must be maintained under operating temperatures at all times to prevent degradation of performance. Each drive tray comes equipped with an extra-large high-efficiency aluminum heatsink lid and thermal pad.
  • Working together with the dual 40mm cooling fans, the heat is further dispersed through the intelligently place ventilation holes throughout the entire enclosure.
  • The dual cooling fans come with three fan speed settings: High, Low, and off. The user can manually select the proper cooling option to keep the drives at optimal operating temperatures.
  • Packed with Features
    An LED status light built into the tray lets you know your drive is powered up and in use. The LED will shut off when no drive is installed to save power.
  • For an additional physical layer of security, the included key-lock can be used to protect against unwanted access and secure drives in rough environments, such as military systems and in-vehicle PCs.
  • Never forget which drives belong in what bays. With our individual drive ID labels, you'll always know which drive tray belongs in your RAID array or which drives contains specific files. Freely unplug and rearrange them to better suit your configurations or remove them for a simplified look.
  • The ToughArmor MB720MK-B V2 supports 15-pin SATA power cables with locking latches. You'll never need to worry about cables unintentionally disconnecting from your enclosure. Once these cables are connected, they will lock and stay in place.

Q: The mounting screws for the device seem to be too short to secure the device onto my system, what should I do?

A: For computer cases that have a thick metal sheet, the included mounting screws (M3*2.5L) may not fully secure the device. Please use longer screws (M3*4L) to secure the device or contact us at tech@icydock.com for replacement screws.


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?

A:The following information is the fan specification requirement and compatible fan models for MB720M2K-B V2

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:

Q: I feel that the drive tray's upper and lower metal spring is stuck when inserting the drive tray. What should I do?

A: Remove the drive tray from the enclosure and reinsert the tray without putting excessive pressure on the metal mesh sheet in front of the tray. Excessive force on the front metal mesh sheet may bend the top and bottom metal spring, causing difficulties when inserting the drive tray. Therefore, please do not forcingly insert the drive tray when this happens as it may cause damage to the metal spring.
