The ICYNano MB861U31-1M2B USB 3.2 Gen 2 10Gb/s tool-less enclosure allows you to swiftly transform your M.2 NVMe PCIe SSD into a portable pocket drive. It is a unique external enclosure where you can swap any length M.2 drives within seconds by using the innovative tool-less M.2 adjustable locker. Utilizing the extra-long 22110 SSD for the intensive workflow with transfer speed up to 10Gb/s through USB 3.2 Gen 2 interface making the ICYNano a perfect tool for media professional editors, computer repair technicians, or daily on-the-go usage.

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

For users that have multiple M.2 drives in different length and require frequent drive change, the patent-pending M.2 adjustable locker lets you quickly place the M.2 NVMe SSD (2230, 2242, 2260, 2280, and 22110) into the drive tray and move the adjustable M.2 locker towards the M.2 NVMe SSD to lock in place.

Professional Enclosure for Enterprise Drives

With the ability to support 22110 (110mm) of M.2 NVMe SSD, the ICYNano let's enterprise users utilize the various type of M.2 NVMe SSDs without limitations. These enterprise 22110 SSDs offer high endurance for reliability, low latency, and the perfect balance of performance, which caters to the IT and media professionals who use data-intensive applications such as 3D animation rendering, video editing, and artificial intelligence applications.

Maximum Cooling Performance

As M.2 NVMe SSDs are notorious for overheating and throttling issues under heavy load, it is essential to have the proper cooling to pair with it. To maximize the cooling efficiency for the best performance, we have developed a dual function high-efficient heatsink lid and include the thermal pad to maintain optimal temperature under any circumstances.


Unlike many generic M.2 NVMe SSD enclosures that use a slide-in SSD design which prevents the SSD from fully touching the thermal pad/metal housing. The ICYNano MB861U31-1M2B's extra-large heatsink lid closes from the top leaves no gap between the SSD and thermal pad to provide the best heat conduction.


In the real-world test, the Samsung 970 Evo Plus SSD runs steadily at 44℃ under full load when used in ICYNano, 18℃ lower than used in generic metal M.2 SSD enclosures, proving ICYNano MB861U31-1M2B offers the best cooling performance in class.

Compact External Enclosure

The ICYNano has been engineered for mobility, with a slim and durable design. The solid metal construction helps ensure that your drive will be fully protected when you’re on the go and can be conveniently fit into your pocket or backpack.

Superior Performance

To fully utilize the power of the M.2 NVMe SSD, the ICYNano uses the USB 3.2 Gen 2 interface that can provide a transfer speed up to 10Gb/s and let you back up large data file and store 4K / 5K / 8K video within seconds.

Ultimate Compatibility

ICYNano comes with both USB Type C to C and C to A cable to support new and legacy PC/Macs that uses different types of USB ports. Using the included cables offers the best performance and compatability instead of using mini USB adapters, which may cause speed reduction and compatibility issues. The ICYNano is a true Plug and Play (no drivers needed) enclosure, designed to be multi-OS compatible. It is compatible with all Thunderbolt types, USB 2.0/3.0, and USB 3.2 Gen 1 for the best results.
