SF3 Series – RED MINI-MAG® Pro Card Reader

Professional dual-slot RED MINI-MAG card reader for computers with Thunderbolt 3 ports.



Imagine The Possibilities…

When you shoot on RED, chances are your footage is captured to RED MINI-MAG® media, known for their quality and durability. With the move to shooting in 8K and at high frame rates, those cards fill up faster than ever—the need for a tool that accelerates offloading footage from multiple cards is greater than ever, too. The Sonnet SF3™ Series – RED MINI-MAG Pro Card Reader is the ultimate tool for the job.

Featuring a dual-port, 40Gbps Thunderbolt™ 3 interface, this RED APPROVED reader ingests footage from RED MINI-MAG memory cards to any Mac®, Windows®, or Linux® computer with Thunderbolt 3 ports—on location, in the studio, or in the edit suite—at the fastest speeds the cards will support.

Dual Card Slots, Less Waiting

The SF3 Series – RED MINI-MAG Pro Card Reader can ingest files simultaneously from two cards at up to 1060 MB/s—more than double the average ingest speed of other RED MINI-MAG card readers—to cut your ingest times in half.
