## Long description

GrauGear G-M2DK-U4-40G is a desktop docking station for M.2 NVMe SSDs offering a USB 3.2 Gen 2 Type-C host interface with up to 40 Gbit/s transfer rate. Constructed from aluminium and plastic in grey, it supports M.2 PCIe NVMe Gen4×4 drives in all common lengths and includes an active cooling fan for thermal management, making it suitable for fast data access, cloning, backups and drive diagnostics.
Advantages
The docking station supports PCIe Gen4×4 NVMe M.2 SSDs and provides high-speed data transfer up to 40 Gbit/s over a USB Type-C connection. Its aluminium and plastic construction offers a balance of durability and heat dissipation, while the built-in 50 mm (5.5 cm) fan and power switch enable controlled active cooling and convenient operation. Compatibility with multiple M.2 lengths allows flexible use with a wide range of SSDs.
Suitable for
Data transfer and file access from M.2 NVMe SSDs
Cloning and imaging SSDs for upgrades or deployment
Backups and data recovery operations
Drive testing and diagnostics on the desktop
When it may not be suitable
This docking station is designed specifically for M.2 PCIe NVMe SSDs and does not support SATA-only M.2 drives or traditional 2.5"/3.5" HDDs without an adapter. It requires a host device with a USB Type-C port; older systems without compatible USB interfaces or lacking sufficient host bandwidth will not achieve the specified 40 Gbit/s transfer rate. The compact desktop form factor is not intended as a permanent in-rack storage solution.
Key specifications
Supported SSD type: M.2 PCIe NVMe Gen4×4
Supported M.2 lengths: 2230, 2242, 2260, 2280, 22110
Maximum transfer speed: up to 40 Gbit/s (USB 3.2 Gen 2 / USB 4.0 bandwidth)
Host interface: USB Type-C (USB 3.2 Gen 2 compatible)
Cooling: built-in active fan, fan diameter 50 mm (5.5 cm)
Material: aluminium and plastic
Colour: grey
How to use
Open the docking station according to the manufacturer's instructions, insert an M.2 PCIe NVMe SSD of a supported length and secure it in place. Connect the docking station to a host computer via a USB Type-C cable. If required, enable the power switch and ensure the fan is operating to manage drive temperature during heavy use. Use standard disk management, cloning or backup software on the host system to access, clone or back up the SSD.
What to consider before purchase
Ensure your SSD is a PCIe NVMe M.2 drive (not SATA M.2)
Verify your host computer has a compatible USB Type-C port and supports the desired bandwidth
Confirm the M.2 SSD length is one of the supported sizes (2230–22110)
Usage recommendations
For sustained high-speed transfers and heavy workloads, keep the built-in fan unobstructed and use a host port that supports the highest available bandwidth. For cloning or imaging operations, connect directly to the host’s Type-C port rather than through low-bandwidth hubs to achieve optimal performance.
