Where to buy

Superfast external AXAGON EEM2-XR RADIATOR box with USB 3.2 Gen 2 interface is designed for NVMe (PCI-Express) M.2 SSD disks. A big advantage of the box is the double disk cooling system and thus the lowest possible temperature of the M.2 SSD disk. 

Sophisticated ribbed body design and internal heat sink provides great M.2 disk cooling. This extends its service life and also prevents the disk from slowing down, so-called "Thermal Throttling". Robust box body also protect the disk.

SuperSpeed USB 10 Gbit/s interface allows you to enjoy the speed of modern M.2 SSD drives. Due the fast USB 3.2 Gen 2 interface the transmission speed is up to 10Gb/s. Comfortable connection allows reversible USB-C connector. The external M.2 box also supports other modern functions, e.g. TRIM.

NVMe M.2 SSD disk up to 22x80 mm can be used in the external box. The box has no SSD capacity limitation. M.2 cards can be single-sided or double-sided.

Inserting M.2 SSD disk into this box you will create a fast and compact external drive. The box can be used with computers and laptops, as well as with OTG-enabled mobile phones and tablets.

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 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): 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 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.

A): Check if the M.2 disk type is NVMe (neither SATA M.2 drives nor mSATA drives are covered by this box)

B): Update the firmware of your NVMe M.2 drive using the manufacturer's utility

C): Update the firmware of the external box - download link
