More Than Two Times the Average Ingest Speed of USB 3.0 Readers

Productivity Enhancer

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.

Thunderbolt 3 —
The USB-C That Does It All

The SF3 Series – SxS Pro Card Reader includes two Thunderbolt 3 ports; the first connects it to your computer, while the second supports daisy chaining of up to five additional Thunderbolt peripheral devices(2) to a single port on your computer. The reader includes 10Gbps USB 3.1 Gen 2 support, meaning you can connect a USB device to the second port using the proper cable or adapter. The SxS reader also provides full support for connecting up to two 4K displays @ 60Hz or one 5K display @ 60Hz(4). For connected devices requiring extra power, 15 watts is provided to bus-powered other devices, such as the SF3 Series – CFast 2.0 Pro Card Reader.

The SF3 Series – SxS Pro Card Reader supports all generations of SxS media, up to the latest E Series cards. When used with the Sony ExpressCard Adapter for XQD Memory Card (QDA-EX1) adapter or the Sonnet SDHC Adapter for SxS Camera Slot (SD-SXS-E34) adapter, you can even use XQD and SD cards, respectively, with this reader.

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 such as additional SxS Pro Card Readers and Sonnet’s CFast 2.0 Pro Card Readers to occupy the same footprint. The SxS reader enables you to daisy chain multiple readers to ingest four, six or more cards simultaneously, taking advantage of Thunderbolt 3’s 2,750 MB/s bandwidth.

Stackable for Customizing Your Workflow with Additional Sonnet SxS or CFast 2.0 Pro Card Readers

Thunderbolt 3 (40Gbps) Cable and ThunderLok 3 Included

Sonnet includes a 0.5-meter Thunderbolt 3 cable to connect the SF3 Series – SxS Pro Card Reader to your computer, and a Sonnet ThunderLok 3 Thunderbolt connector retainer clip(5) to secure the cable to the reader. Accidentl cable disconnect can lead to data loss. Sonnet’s ThunderLok 3 secures the Thunderbolt cable to the SxS reader, and is easy to install and use—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 does not attach to the connector, but remains on the cable so it won’t get lost when not in use.
