SMUGDESK

SMUGDESK USB 3.2 Gen2×2 20Gbps M.2 NVMe SATA Adapter RTL9220

SKU CH-TZ89-Q21T3

Connects M.2 NVMe and SATA SSDs via USB 3.2 Gen2×2 at 20Gbps using an RTL9220 controller

  • 20Gbps transfer speed via USB 3.2 Gen2×2 RTL9220 controller
  • Works with NVMe MKey and SATA B/B+MKey M.2 SSDs
  • Type-C output for plug-and-play connection to PCs and laptops
  • Compact riser board design for portable external storage expansion
  • Compatible with Windows macOS and Linux without extra drivers

High-speed M.2 to USB-C adapter

The SMUGDESK adapter uses an RTL9220 controller to connect M.2 NVMe MKey or SATA B/B+MKey SSDs to a USB 3.2 Gen2×2 Type-C port at 20Gbps. It targets users who need fast external storage without opening their computer. The board works with Windows, macOS and Linux without extra drivers. It suits anyone turning a spare internal drive into a portable device.

Passive cooling on a compact riser

The small riser board has no fan, so it runs silently and draws power only from the USB connection. Heat dissipates through the PCB and the metal shielding of the attached SSD. Under sustained transfers the drive may warm up, but the adapter itself adds no active noise or extra power demand. It is built for typical file-copy workloads rather than continuous server duty.

Plug-and-play with no bundled software

The package includes only the adapter board; no cables, enclosures or utilities are supplied. Users must provide their own USB-C cable and manage the SSD with standard operating-system tools. The lack of proprietary software means no background services or licence keys to maintain. It simply exposes the drive as a native block device.

Questions about this item

How do I install an M.2 NVMe or SATA SSD onto the RTL9220 riser board and connect it via USB Type-C?

Insert the SSD into the M-key or B+M-key slot at an angle, press down and secure with the screw, then plug the Type-C cable into a USB 3.2 Gen2×2 port for up to 20Gbps.

Will the RTL9220 controller or Type-C connector need replacement after heavy daily use?

The RTL9220 controller is soldered on the board and the Type-C connector is rated for thousands of cycles; neither is user-serviceable, so the whole adapter is replaced if either fails.

What speed ceiling appears first during long sequential transfers with this 20Gbps adapter?

Sustained throughput is limited by the SSD’s own sequential rating and thermal throttling, not by the RTL9220 or the USB 3.2 Gen2×2 link.
