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.

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.

Equipment size and design features matter.
