Dual-Slot RED MINI-MAG Pro Reader

The Sonnet SF3 Professional is a Thunderbolt 3 card reader built for high-resolution content creation. It ingests footage from two RED MINI-MAG cards simultaneously. A durable aluminum enclosure ensures reliable operation on location or in the studio. The compact, stackable design saves workspace and integrates into existing setups.

For RED camera workflows

This reader suits photographers and videographers offloading 8K and high-frame-rate footage from RED MINI-MAG media. It is not for users working with CFexpress, SD or other card formats. Buyers without a Thunderbolt 3 host connection cannot use this device. It does not serve as a general-purpose multi-format reader.

Up to 1060 MB/s simultaneous transfer

Dual-slot operation delivers speeds up to 1060 MB/s, drastically reducing offload time for large video files. This throughput is the key metric for matching the reader to your post-production pipeline. Verify your workstation provides a Thunderbolt 3 port to achieve this performance.

Questions about this item

Should I pick the single-slot or dual-slot version of this reader?

This model is the dual-slot version, so you can offload two RED MINI-MAG cards at the same time.

What does the 1060 MB/s figure mean when I am actually copying footage?

It represents the peak combined throughput when both slots are active, letting you ingest high-resolution RED footage much faster than single-slot alternatives.

How does the Thunderbolt connection affect the speeds I will see?

The Thunderbolt 3 interface provides enough bandwidth to sustain the reader's 1060 MB/s maximum without capping the transfer.
