SxS PRO X Thunderbolt Single-Slot Card Reader
Compact Professional SxS PRO X Card Reader for Computers with Thunderbolt 4 or Thunderbolt 3 Ports

Supports SxS PRO X Cards at Full Speed
Superior Ingest Performance
Co-developed by Sony®, SxS™ professional memory cards are the onboard recording media used in many past and current Sony and ARRI® pro digital video cameras and camcorders. The latest generation of exceptionally fast memory cards—SxS PRO X—offer a nearly 3x increase in maximum read speeds of the previous generation. If you use SxS media in your workflow, you should use an SxS card reader capable of supporting SxS PRO X and every other SxS memory card at maximum speed. For the fastest ingests, get a Sonnet SxS PRO X Thunderbolt™ Single-Slot Card Reader; it’s the best tool for the job.

Small and Ultra-fast
Ingest at Maximum Read Speeds
The SxS PRO X Thunderbolt Single-Slot Card Reader is small, ultra-fast, and easily reads all SxS memory cards at their rated speeds

The Perfect Travel Companion
Bus-Powered Operation
When you need to travel light and don’t have a large stack of cards to ingest, extra power bricks and cables take up extra space and can weigh you down. Sonnet’s SxS PRO X Thunderbolt Single-Slot Card Reader is bus-powered, operating off its Thunderbolt connection so there’s no need to plug in a power supply or power cable.

Superior Ingest Performance
Ingests footage from any SxS card at maximum supported speeds; up to 1250 MB/s with SxS PRO X, and up to 440 MB/s for SxS Pro+ media(1).

Bus-powered
Ideal for use with a laptop computer when no power outlet is available.

PCIe 3.0 x4 Thunderbolt 3 Device
This Thunderbolt 3 card reader provides 2 lanes of PCIe 3.0 to the SxS PRO X card slot. A Thunderbolt 4 device would be limited to one lane total. Learn more about Thunderbolt 3 performance benefits over Thunderbolt 4.

Equipment size and design features matter. Sonnet’s SxS PRO X Thunderbolt Single-Slot Card Reader measures just 2.8 inches wide by 4.1 inches deep by 0.8 inches tall (about the size of a deck of playing cards), making it suitable for use in any workspace and workflow. Featuring a rugged aluminum enclosure, the Sonnet reader packs easily into a computer bag or backpack. Its single-port Thunderbolt interface and bus-powered operation make it perfect for use at the end of a daisy chain (such as multiple Sonnet SF3™ Series dual-slot pro card readers).

40Gbps Thunderbolt
Fastest External Interface Available
Featuring a 40Gbps Thunderbolt 3 interface, this reader ingests footage from all SxS memory cards to any Mac or Windows computer with Thunderbolt 4 or Thunderbolt 3 ports—on location, in the studio, or in the edit suite—at the fastest speeds(1) the cards will support.

All the Right Connections
40Gbps Thunderbolt Cable and ThunderLok 3 Included
Sonnet includes a 0.5-meter Thunderbolt 3 cable that supports Thunderbolt's full 40Gbps bandwidth, and is fully compatible with Thunderbolt 4 computers. Sonnet also provides a ThunderLok 3 Thunderbolt connector retainer clip(3) 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.
