Product Description
The Sonnet SF3 Series – RED MINI-MAG Pro Card Reader is the ultimate solution for offloading RED footage fast. When you shoot on RED, your media is stored on RED MINI-MAG cards—known for their durability and quality. With today’s 8K and high frame rate productions, those cards fill up faster than ever, and fast ingest is critical to your workflow.
Featuring a dual-port, 40Gbps Thunderbolt 3 interface, this RED APPROVED reader ingests footage from RED MINI-MAG cards to any Mac, Windows, or Linux computer with Thunderbolt 3 ports—on location, in the studio, or in post-production—at the fastest speeds your media can deliver.
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 speed of typical RED MINI-MAG readers—cutting your ingest times in half and keeping your workflow moving fast.
Compact, rugged, and ready for pro use, this reader also includes a Thunderbolt cable and ThunderLok connector lock. It’s stackable, rack-mountable, and even backward compatible with older Macs via an Apple Thunderbolt 3 to Thunderbolt 2 adapter.
