Product Identity

The Hetai Tech SCRM331 is an 8-in-1 card reader with a USB 3.0 interface for laptops, desktops and tablets. It accepts SD and TF cards up to 512G capacity and works with Windows, Mac OS and Linux without driver installation.

Thermals Noise Power

The reader draws power directly from the USB 3.0 port and has no fan or moving parts, so it adds no audible noise to the workstation. Normal operation stays cool to the touch during sustained file transfers.

Accessories Impact

A lanyard buckle is moulded into the body to reduce the chance of misplacing the adapter. The safety-head design shields the USB connector from physical damage when the reader is carried in a bag.

Questions about this item

How do I connect the SCRM331 to my laptop and which slot do I use for an SD card?

Plug the USB 3.0 connector into any free USB port; the reader is hot-swap and driver-free. Insert the SD card into the larger SD slot — the smaller slot is for TF or microSD cards only.

Will the card slots or the USB connector wear out and need replacement?

The USB connector has a safety-head cover that shields the contacts when the reader is not in use, reducing wear. The SD and TF slots are fixed solid-state contacts with no moving parts, so no scheduled replacement is required.

What caps the transfer speed when I move large files continuously?

The USB 3.0 interface limits sustained throughput to its 5 Gbps theoretical maximum, and the reader supports cards up to 512 GB, so the bus ceiling is reached before the storage media.
