Sonnet SF3 Series: The Ultimate Dual-Slot RED MINI-MAG Thunderbolt 3 Reader

Accelerate your post-production workflow and eliminate ingest bottlenecks with the Sonnet SF3™ Series RED MINI-MAG Pro Card Reader. As a RED-approved solution, this dual-slot ingest station is meticulously engineered for professionals shooting in 8K and high frame rates, where media cards fill up faster than ever. When every second on set or in the edit bay counts, waiting for footage to offload is not an option. The SF3 reader is your tool for reclaiming valuable time.

At the heart of this reader is a blazing-fast 40Gbps Thunderbolt™ 3 interface, enabling you to transfer footage from two RED MINI-MAG cards simultaneously to any Mac®, Windows®, or Linux® computer. By leveraging both slots, you can achieve combined read speeds of up to 1060 MB/s, effectively cutting your ingest times in half compared to single-slot solutions. This dramatic speed increase means you can move from offloading to editing faster, boosting productivity whether you're on a remote location, in the studio, or finalizing a project in the edit suite.

Built for the rigorous demands of Digital Imaging Technicians (DITs) and high-pressure production environments, the SF3 reader features a compact and rugged extruded aluminum enclosure for reliable, go-anywhere performance. Its intelligent, stackable design allows you to daisy-chain multiple SF3 Series readers (for RED MINI-MAG, SxS, and CFast 2.0 cards) via its second Thunderbolt 3 port. This lets you create a custom, high-volume ingest station with a minimal footprint, ingesting from four, six, or more cards at once. For fixed installations, integrated threaded mount points allow for securing two readers side-by-side on a standard 1U rack tray, seamlessly integrating into your professional gear setup.
