Supports SxS PRO X Cards at Full Speed

Superior Dual-Slot Ingest Performance

SxS professional memory cards are used in many past and current Sony and ARRI pro digital video cameras and camcorders. Sony’s latest cards — SxS PRO X — take a performance leap by offering nearly 3x the maximum read speeds over previous generation cards. While Sony Venice Cinema Camera and PXW-Z750 XDCAM exploit SxS PRO X cards’ enhanced performance capabilities, even users of compatible Sony video cameras, such as PXW-X400 and PXW-Z450, can take advantage of the cards’ read speed potential. Using a single Thunderbolt cable, it’s compatible with Apple M series Macs or Intel Macs with Thunderbolt 3 ports, as well as Windows computers with Thunderbolt 5 or Thunderbolt 4 ports.

When it’s time to ingest footage to your computer, don’t settle on any old card reader — for the shortest ingest times, SxS PRO X cards require a card reader designed to support their maximum ingest speeds (and, for even greater efficiency, a dual-slot card reader that can ingest two cards simultaneously). Get a Sonnet SF3™ Series – SxS PRO X Card Reader; it’s the fastest tool for the job.

Designed for the Fastest Connection to Thunderbolt Computers

SF3 Series Professional Media Card 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. Watch this video to learn more about the performance benefits.

Bus-Powered Option Available

Do you need the fastest ingest speeds but need to travel light — extra power bricks and cables take up extra space and can weigh you down — and don’t have a large stack of cards to ingest? Check out Sonnet’s SxS PRO X Thunderbolt Single-Slot Card Reader. It’s bus-powered, operating off its Thunderbolt connection so there’s no need to plug in a power supply or power cable, and reads SxS PRO X cards at rated speeds.
