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. 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. For the fastest ingests, get a Sonnet SxS PRO X Thunderbolt Single-Slot Card Reader; it’s the best tool for the job.

Sonnet SxS PRO X media card reader is small, ultra-fast, and easily reads all SxS memory cards at their rated speeds.
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. SxS PRO X media card reader is bus-powered, operating off its Thunderbolt™ connection so there’s no need to plug in a power supply or power cable.
Ingests footage from any SxS card at maximum supported speeds; up to 1250 MBps with SxS PRO X, and up to 440 MBps for SxS Pro+ media.
Ideal for use with a laptop computer when no power outlet is available.
Pro media card reader provides four lanes of PCIe bandwidth for maximum performance.
Supports all SxS media, including SxS PRO X and SxS PRO+ E Series cards. SD cards are supported when used with adapter.
Small and rugged aluminum enclosure for easy packability and reliable operation.
Powered through its Thunderbolt connection, SxS PRO X media card reader requires no power adapter.
Compatible with Mac and Windows. See Tech Specs for details.

Sonnet’s SxS PRO X media card reader supports SxS media up to the latest PRO X cards.
Equipment size and design features matter. Sonnet’s SxS PRO X media 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).
Featuring a high-bandwidth Thunderbolt interface, this media card reader ingests footage from all SxS memory cards to supported Thunderbolt Mac and Windows computers — on location, in the studio, or in the edit suite — at the fastest speeds the cards will support.


Many Sonnet Thunderbolt products featuring Thunderbolt ports come equipped with threaded mounting holes to securely attach a Sonnet ThunderLok connector lock, preventing Thunderbolt cables from accidentally disconnecting.
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.
