SMUGDESK M.2 to USB-C adapter board with RTL9220 chip

SMUGDESK

SMUGDESK USB 3.2 Gen2x2 20Gbps M.2 SSD Adapter RTL9220

SKU CH-TK5A-YSASW

Connects M.2 NVMe or SATA SSDs via USB 3.2 Gen2x2 at 20Gbps using an RTL9220 controller

  • Up to 20Gbps transfer speed with USB 3.2 Gen2x2
  • Dual protocol support for M-Key NVMe and B/B+M Key SATA SSDs
  • RTL9220 chip provides stable and efficient performance
  • Converts M.2 interface to Type-C for flexible connectivity
  • Compact riser board design enables portable external storage

USB 3.2 Gen2x2 M.2 Adapter

The SMUGDESK adapter uses the RTL9220 chip to convert an M.2 M-Key NVMe or B/B+M Key SATA SSD into a USB Type-C device. It operates at the USB 3.2 Gen2x2 standard with a maximum transfer speed of 20Gbps. The compact riser board is designed for building portable high-speed external storage.

Builders needing dual-protocol M.2 support

This adapter suits users who want one enclosure that accepts both NVMe and SATA M.2 modules. It is not for buyers who require a bridge that only handles a single protocol. It is also not for setups where the host system lacks a USB 3.2 Gen2x2 Type-C port to reach the rated throughput.

RTL9220 dual-protocol bridge

The RTL9220 controller is the specification that determines compatibility. It enables simultaneous support for NVMe and SATA M.2 drives on a single Type-C connection. If your workflow demands a different controller or protocol combination, this board will not meet that requirement.

Questions about this item

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

Insert the M-Key NVMe or B/B+M Key SATA drive into the M.2 slot at the correct angle, secure it with the mounting screw, then plug the board's Type-C port into a USB 3.2 Gen2x2 port for up to 20Gbps bandwidth.

What maintenance or part replacement will this adapter need over time?

The RTL9220 riser board itself has no moving parts or serviceable components; only the installed M.2 SSD may eventually require replacement after its write-endurance limit is reached.

What is the first performance limit I will hit during sustained transfers with this USB 3.2 Gen2x2 adapter?

The USB 3.2 Gen2x2 interface caps sustained throughput at 20Gbps, so long sequential reads or writes will saturate that link before the RTL9220 chip or the SSD becomes the bottleneck.
