Quick Link:
Q: I'm connecting my Oculink or SlimSAS NVMe PCIe HBA/RAID card to the MB720M2K-B via miniSAS HD (SFF-8643) interface, but the U.2 drives did not show up in my system.
A: The MB720M2K-B are not compatible with the Oculink or SlimSAS PCIe HBA/RAID cards due to different connector pin assignments used on the device. Please check the compatibility list in the FAQ section for HBA/RAID cards that are compatible with MB720M2K-B.
Q: Can you recommend an add-on card that works with MB720M2K-B?
A: The following add-on cards are compatible with MB720M2K-B. We highly recommend using the official cable for the best compatibility.
We are currently certifying our NVMe enclosure with the major add-on card manufacturers. We will be adding compatible add-on cards to the list.
You can click here to report a compatible add-on card/cable. If you want to check the compatibility of add-on card(s) that are not on the list, please click here.
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.
Windows 7 – Right-click on the computer icon on the desktop, select properties, click device manager, right-click on the disk drive icon and then 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?
A:The following information is the fan specification requirement and compatible fan models for MB720M2K-B
| Fan Dimension (LxWxH) | 40 x 40 x 10mm | 40 x 40 x 20mm |
| Connector Type | 3 Pin Wafer | |
| Rated Voltage (VDC) | 12V DC | |
| Rated Current (A) | < 0.12A (127mA) | |
| Screw Specification | Phillips Flat Head - M3 x 15mm - Steel (Came with stock fan) |
Phillips Flat Head - M3 x 25mm – Steel (Not Included) |
Compatible fan models

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.

| Please DO NOT put excessive pressure on the metal mesh sheet as shown |
