When you shoot on RED, chances are your video footage is captured to RED MINI-MAG media, known for their quality and durability. With the move to shooting demanding 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. Sonnet SF3™ Series - RED MINI-MAG Pro Card Reader is the ultimate tool for the job. Featuring a dual-port, high-bandwidth Thunderbolt™ interface, this RED APPROVED reader ingests footage from RED MINI-MAG memory cards to your computer at the fastest speeds the cards will support.

The ability to ingest multiple cards simultaneously at full speed means you can complete the process — without swapping any of your cards — in as little as one sixth the time required using a single-slot reader!

Ingests footage from RED MINI-MAG cards at up to maximum supported speeds. Simultaneously ingest from two cards at full speed.
Enable simultaneous ingest of files from two cards up to 1060 MB/s aggregate.
Pro media card reader provides four lanes of PCIe bandwidth for maximum performance.
Small and rugged aluminum enclosure for reliable operation; design enables multiple SF3 Series pro card readers to occupy same footprint.
Threaded mount points enable secure attachment of two readers side-by-side on a rack tray in just 1U of rack space.
One port connects to computer; second port supports daisy chaining additional SF3 Series pro card readers.
Compatible with Mac, Windows, and Linux. See Tech Specs for details.
