Sonnet SF3 Dual-Slot RED MINI-MAG to Thunderbolt Pro Card Reader
Model: SF3-2RMM
About: Sonnet SF3 Dual-Slot RED MINI-MAG to Thunderbolt Pro Card Reader
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.
Features
- Superior Ingest Performance - Ingests footage from RED MINI-MAG cards at up to maximum supported speeds. Simultaneously ingest from two cards at full speed.
- Dual Card Slots - Enable simultaneous ingest of files from two cards up to 1060 MB/s aggregate.
- PCIe 3.0 x4 Thunderbolt Device - This Thunderbolt 3 device provides four lanes of PCIe 3.0 (two lanes to each card slot). Thunderbolt 4 would be limited to one lane total. Learn more about Thunderbolt 3 performance benefits over Thunderbolt 4.
- Compact, Rugged, Stackable - Small and rugged aluminum enclosure for reliable operation; design enables multiple SF3 Series pro card readers to occupy same footprint.
- Rackable - Threaded mount points enable secure attachment of two readers side-by-side on a rack tray in just 1U of rack space.

Ingest Six Cards Simultaneously - In the Same Time as Just One Card in a USB Reader
The ability to ingest multiple cards simultaneously at full speed means you can complete the process — without swapping cards — in as little as one sixth the time required using a single-slot reader!
Dual Card Slots, Less Waiting - Ingest from Two Cards at up to 1060/MBs
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.
RED Ready. Rack Ready. - The Perfect Mobile RED Ingest Station
Sonnet’s SF3 Series pro card readers include threaded mount points that enable you to securely attach two readers side-by-side on a rack tray in just 1U of rack space.
Designed for Digital Imaging Technicians - Portable, Rugged, Stackable
Measuring 5.8 inches wide by 1.4 inches high by 6.1 inches deep, the SF3 Series - RED MINI-MAG Pro Card Reader is suitable for use in any workflow and workspace; for DITs working multi-camera shoots or in a small space, the Sonnet reader’s design advantages stand out.
Sonnet SF3 Series Pro Card Readers - Designed to be Stacked and Daisy Chained
SF3 Series pro card readers feature rugged aluminum enclosures designed to be stacked and daisy chained, enabling multiple AJA PAK Media, CFast 2.0, CFexpress/XQD, RED MINI-MAG, and SxS PRO X readers to occupy the same footprint, while connecting to your computer through a single cable. You can take advantage of Thunderbolt’s up to 2800 MBz/s of PCIe 3.0 x4 bandwidth to ingest four, six, or more cards simultaneously!
40Gbps Thunderbolt - Fastest External Interface Available
Featuring a dual-port 40Gbps Thunderbolt interface, this reader ingests footage from all RED MINI-MAG memory cards to Mac and Windows computers with Thunderbolt 4 or Thunderbolt 3 ports — on location, in the studio, or in the edit suite — at up to the fastest speeds the cards will support.
- Dual 40Gbps Thunderbolt Ports - One port is reserved for the connection to your Thunderbolt 4 or Thunderbolt 3 computer; the second port enables expansion of up to five additional Thunderbolt peripheral devices in a daisy chain.
- 10Gbps USB 3.2 Gen 2 Support - 10Gbps USB 3.2 Gen 2 support allows you to connect a USB device to the second Thunderbolt port using the proper cable or adapter.
- Provides 15W of Power - For peripherals requiring extra power, 15 watts is provided to bus-powered devices.
- Supports Connecting One 5K 60Hz Display - Maximize the utilization of one computer Thunderbolt port.
All the Right Connections - 40Gbps Thunderbolt Cable and ThunderLok 3 Included
Sonnet includes a Thunderbolt cable that supports Thunderbolt’s full 40Gbps bandwidth, and is fully compatible with Thunderbolt 4 and Thunderbolt 3 computers. Sonnet also provides a ThunderLok 3 Thunderbolt connector retainer clip that prevents accidental cable disconnections — just slide it over one end of the cable, and then plug in the connector and secure it to the reader by turning a thumbscrew. Because of its unique design, ThunderLok remains on the cable so it won’t get lost when not in use.
Compatible with Thunderbolt 4 Computers and Apple M series Macs
SF3 Series professional card readers are fully compatible with Thunderbolt 4 computers, including Apple M series Macs. Sonnet’s media readers are purposely designed with a Thunderbolt 3 controller and its four lanes of PCIe (not available in a Thunderbolt 4 peripheral) to achieve maximum simultaneous ingest speeds.
Backward Compatible with Older Macs
No Thunderbolt 4 or Thunderbolt 3? No problem — SF3 Series - RED MINI-MAG Pro Card Reader is also compatible with Macs with Thunderbolt 2 or Thunderbolt ports when used with the bi-directional Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter and a Thunderbolt cable (both sold separately).
