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

Mac | Windows

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.

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.

Built for Two - Read up to 2500 MB/s | Dual-Slot Ingest at Maximum Read Speeds

The SF3 Series - SxS PRO X Card Reader easily reads all SxS memory cards at their rated speeds, with simultaneous aggregate performance of two cards up to 2500 MB/s.

Key Features | Superior Ingest Performance

Ingests footage from all SxS cards at up to maximum supported speeds. Simultaneously ingest from two cards at full speed.

Broad SxS Card Support

Supports all SxS media, including SxS PRO X, SxS PRO+ E Series, and SxS-1 cards.

PCIe 3.0 x4 Thunderbolt 3 Peripheral

Thunderbolt 3 provides four lanes of PCIe 3.0, two lanes to each SxS PRO X card slot (a Thunderbolt 4 device wound be limited to one lane total).

Compact, Rugged, Stackable

Small and rugged aluminum enclosure for reliable operation; design enables multiple SF3 Series card readers to occupy same footprint.

Rackable

Threaded mount points enable secure attachment of two readers side-by-side on a rack tray in just 1U of rack space.

Two 40Gbps Thunderbolt Ports

One port connects to computer; second port supports daisy chaining of up to five additional SF3 Series pro card readers.

Forward Compatible

Sonnet Thunderbolt 3 Pro Readers are fully compatible with Thunderbolt 4 computers, and are purposely designed with Thunderbolt 3 which has four lanes of PCIe 3.0 available.

Backward Compatible

Compatible with Thunderbolt 2 and Thunderbolt Macs when used with an Apple® Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter and a Thunderbolt 2 cable (both sold separately).
