Where to buy

External box AXAGON EEM2-U3C is designed for SATA M.2 SSD drives. It is equipped with a modern SuperSpeed USB-C connector for easy and reliable connection.
SATA 6G interface with UASP and USB 3.2 Gen 1 support allows you to enjoy the speed of modern M.2 SSD drives.
The external box supports TRIM function to reduce the gradual degradation of SSD performance over time. Booting from an SSD in an external box is also supported.
In external box you can use B key and B&M key SATA M.2 SSDs up to 22x80 mm without limiting the maximum capacity of the SSD.
M.2 cards can be both single-sided or double-sided.


The box is equipped with a double-sided USB-C connector, which offers a convenient and fast connection without having to find the correct orientation of the cable.
The USB-C connector also ensures reliable contact without the risk of accidental disconnection of the external drive.
The included 25 cm connection cable is equipped with the most common and thus the most versatile type A USB connector.
A decently lit blue LED indicates that the computer is connected to the USB port with a permanent light and flashing when transferring the data.
For efficient operation, the external box is programmed to suspend the drive after 5 minutes of inactivity.


The clever design of the box makes it easy to mount and dismount the M.2 drive thanks to the latches mount.
To complete the assembly, simply screw a single screw into the box body and the external drive is ready for use.
The smart aluminium body is not only durable, but also ensures sufficient SSD cooling.
Installation on supported operation systems is completely automatic. The external drive can be connected
not only to computers and laptops, but also to cell phones and tablets if they have OTG support.


Aluminium external box AXAGON EEM2-U3C with USB 3.2 Gen1 (USB 3.0) is designed for SATA M.2 SSD disks.

SATA 6G interface with UASP support allows you to enjoy the speed of modern M.2 SSD drives. The transmission rate amounts to 5Gb/s thanks to the fast USB 3.2 Gen 1 interface. The external M.2 box also supports other modern functions, e.g. TRIM.

In the external box, SATA M.2 SSD disks with a size up to 22x80 mm can be mounted. The box is not limited by capacity of SSD disks. M.2 cards may be one-sided or double-sided.

Screwless mounting of the inserted M.2 SSD with latches ensures very easy assembly and disassembly, aluminum body allows good cooling.

Insert the M.2 SSD disk into this box and you can easily form a fast and compact external disk.The Box can be used with both computers and laptops, so with mobile phones and tablets with the OTG supporting function.

A): By initializing the disk, you can set the mode in which the hard disk will work

B): You can use the partition with the master boot record (MBR) or the GUID partition table (GPT). For disk up to 2TB, use the MBR option, we recommend selecting GPT on a larger disk than 2TB. Subsequently, the initialized disk should be formatted.

A): The newly purchased disk must be initialized before first use.

B): If the new disk is not initialized automatically, open "Disk Management", right-click on the desired disk and initialize it.

A): Drivers are included with operating systems and are installed completely automatically. The external box (adapter / docking station) is detected as a standard storage device, such as a USB flash disk, no additional drivers are needed.

B): No other drivers need to be installed and are not even available. If you continue to have problems with your external box (adapter / docking station), check out more tips that can help you troubleshoot problems.

A): If the external box (adapter / docking station) is not displayed in "Device Manager", there may be a USB port malfunction. It is also possible that your computer has a poor power supply to USB ports and the power is not sufficient to operate an external box (you can detect by listening that HDD is not spinning). This is a problem especially for older computers, where the source part already works at the limit of its parameters. In this case, it would help to use a USB hub, with an auxiliary power supply, by which the external box (adapter / docking station) would be connected to the computer.

B): Try plugging the external box (adapter / docking station) into another USB port, preferably on the back of your PC. The external box (adapter / docking station) should be detected and the drivers loaded automatically. If the problem persists, plug the external box (adapter / docking station) into the USB port of another computer to verify its functionality.

A): If this happens, it means that the operating system failed to get the necessary information to install the drivers.

B): The cause may be a defective USB cable or damaged device. If the problem persists, plug the external box (adapter / docking station) into the USB port of another computer to verify its functionality.

A): If this happens, it means that the Windows operating system did not assign a drive letter to the new storage device.

B): If the drive letter is not assigned, open "Disk Management", right-click on the desired drive and manually assign the drive letter. If the drive letter can not be assigned to the disk, it is possible that the disk is formatted as "dynamic". If you want to keep disk data, connect it to the original device and make a backup of the disk. Then convert it to a normal disk, initialize it to MBR (or GPT, see other points), and then perform Low Level Format (e.g. using the Low Level Format Tool)

A): The external AXAGON boxes (adapters / docking stations) support the USB Mass Storage protocol making it easy to connect to TV.

B): When using a disk larger than 2TB, some TVs do not support GPT format. In such case, MBR format must be used when initializing a disk.
