A New Pro Card Reader Arrives From Sonnet


The first in a new family of professional media readers that feature a 40Gbps Thunderbolt 3 interface has hit the marketplace.

Sonnet Technologies’ new SF3 Series — CFast 2.0 Pro Card Reader employs dual card slots and can receive files simultaneously from two cards at concurrent data transfer speeds up to 1,000 MB/s.

Sonnet says this is more than double the average ingest speed of USB 3.0 card readers.

“Our CFast 2.0 Pro Card Reader was designed to meet the time-sensitive demands our customers face on location as they ingest footage from Canon, ARRI, and Blackmagic Design professional cameras,” says Sonnet CEO Robert Farnsworth. “Not only do they need a rugged and portable reader, but they also need to be able to ingest a whole stack of CFast cards as quickly as possible. The SF3 Series — CFast 2.0 Pro Card Reader gives users the ability to ingest content from two cards at once and at the fastest speeds the cards will support.”

Measuring 5.75 inches wide by 3.5 inches deep by 1 inch tall, the CFast 2.0 Pro Card Reader’s shell is made from extruded aluminum. The reader features a user-replaceable, captive 0.5-meter Thunderbolt 3 (40Gbps) cable with USB-C connector, and it is bus-powered with no power adapter required.

Sonnet’s SF3 Series — CFast 2.0 Pro Card Reader (part number SF3-2CFST) became available Monday (5/22) with a suggested retail price of $199.
