Product Description
Next Generation Ingest. Supports SxS PRO X Cards at Full Speed
The Sonnet SxS PRO X Thunderbolt 3 Single-Slot Card Reader is the perfect choice for today’s high-speed production workflows. Co-developed by Sony, SxS professional memory cards are trusted media for many Sony and ARRI digital cinema cameras. The latest SxS PRO X cards deliver nearly 3x faster read speeds than previous generations — and this reader ensures you get every bit of that performance.
When you’re traveling light, bus-powered operation makes a huge difference — no extra power brick needed. The Sonnet SxS PRO X Thunderbolt 3 Single-Slot Card Reader runs entirely off its Thunderbolt connection, keeping your kit compact and ready to go anywhere.
Supports all SxS Media: This versatile reader works with all generations of SxS cards, including SxS PRO X, SxS PRO+ E Series, and SxS-1. It also supports XQD cards via Sony’s ExpressCard Adapter (QDA-EX1), and SD cards via Sonnet’s SDHC Adapter for SxS Slot (SD-SXS-E34).
Perfect for DITs, the reader’s pocket-sized aluminum enclosure is just 2.8 x 4.1 x 0.8 inches — roughly the size of a deck of playing cards — and it fits easily in a backpack or laptop bag. Its single-port Thunderbolt design makes it ideal for use at the end of a daisy chain with other Sonnet SF3 Series readers.
Sonnet includes everything you need — a 0.5-meter Thunderbolt 3 cable and ThunderLok 3 connector retainer to keep your connection secure during critical transfers.
