Card reader Satechi ST-TCU3CRM USB 2.0 Type-C — SD, MicroSD, Grey, internal, 312 Mbit/s

Satechi ST-TCU3CRM is an internal USB Type-C card reader designed for convenient access to SD and MicroSD (TransFlash) memory cards. The compact aluminium housing in grey measures 56.8 × 10.6 × 37 mm and weighs 25 g, allowing installation inside a compatible device or enclosure while providing a Type-C interface for file transfers. The reader supports card compatibility for SD and MicroSD formats and operates over a USB 2.0 connection with a stated maximum data transfer rate of up to 312 Mbit/s.

Advantages

The card reader offers simultaneous MicroSD and SD card access in a slim, internal form factor that conserves space. Its aluminium construction provides a durable, low-profile enclosure and a neutral grey finish that integrates with a range of devices. The Type-C interface enables straightforward connection for devices that accept internal Type-C card readers, and the stated transfer rate supports relatively fast reading and writing of photos and media compared with typical USB 2.0 peripherals.

Suitable for

• Transferring photos and video files from SD and MicroSD cards to a host with internal Type-C support
• On-site media management for photographers and videographers using SD/ MicroSD cards
• Data backup and file access where a compact internal card reader is required

How to use

Install the card reader into a compatible internal slot or enclosure following the host device manufacturer's instructions for internal Type-C modules. Insert an SD or MicroSD card into the corresponding slot until it clicks into place. Connect the device's internal Type-C connection so the host system recognises the reader over USB 2.0. Use the host operating system's file manager to browse, copy or move files between the card and host storage. Safely eject the card from the operating system before removing the card to avoid data loss.

Recommendations

For reliable results, use SD and MicroSD cards that comply with SD Association standards and ensure the host system supports USB 2.0 internal Type-C devices. Regularly back up important files and avoid removing cards during active file transfers. If higher sustained transfer speeds are required for professional UHS-II workflows, verify host compatibility and consider external UHS-II devices that use higher-bandwidth interfaces.
