—Superior Performance—
For years, pro digital video camera pioneers Sony and ARRI have used SxS professional memory cards for capturing footage on select cameras, relying on the cards for their durability and speed. With the move to shooting in 4K and higher frame rates, cards fill up faster than ever, and the need for a truly high-speed card reader with the fastest interface available is undeniable. Sonnet’s SF3 Series - SxS Pro Card Reader fills the bill. Featuring a 40Gbps Thunderbolt™ 3 interface, this device quickly ingests footage from SxS memory cards to any Mac or Windows computer with Thunderbolt 3 ports—on location, in the studio, or in the edit suite—at the fastest speeds the cards will support*.

—Industry’s First SxS Card Reader for Thunderbolt 3—
The SF3 Series - SxS Pro Card Reader is the industry’s first SxS card reader for Thunderbolt 3. This dual-slot reader takes advantage of Thunderbolt 3’s 40Gbps bandwidth to ingest files simultaneously from two cards at maximum speed—more than double the average ingest speed of USB 3.0 card readers. Using the Sonnet SxS reader enables you to ingest footage from multiple cards in much less time for a significantly more efficient workflow.

—Compact, Rugged, and Stackable; Ingest Four or More Cards Simultaneously—
The SF3 Series - SxS Pro Card Reader—measuring a compact 5.75 inches wide by 1 inch high by 5.1 inches deep—is suitable for use in any workspace. The reader’s extruded aluminum shell makes it lightweight, yet rugged enough to be transported in an equipment bag without fear of damaging the case. SF3 Series card readers are designed to be stacked, allowing multiple readers to occupy the same footprint. The SxS reader’s dual-port Thunderbolt 3 interface enables you to daisy chain up to six readers and connect them to your computer through a single cable, taking advantage of Thunderbolt 3’s 2,750 MB/s bandwidth to ingest four, six or more cards simultaneously.

—Ready for Racking—
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.
