General Features

With the increasing popularity of professional digital cinema cameras from RED, Canon, ARRI, and Blackmagic Design, the use of CFast 2.0 memory cards has soared, and the need for a truly high-speed card reader is undeniable.

Featuring a 40 Gb/s Thunderbolt interface, this RED APPROVED device quickly ingests footage from CFast memory cards to your Mac or Windows computer with Thunderbolt 4 or Thunderbolt 3 ports at the fastest speeds the cards will support.

question

Has anyone used this with the Apple thunderbolt 2 to 3 adapter to plug into a Mac with thunderbolt 2 ports?
Asked by: Daniel
In order to use the Apple Thunderbolt 3 to Thunderbolt 2 adapter you would need the device to have a female Thunderbolt 3 port. Since the cable is attached on the Sonnet SF3 Series CFast 2.0 Pro 3 Card Reader B&H # SOSF32CFST, it will not be able to connect to the adapter.

Under key features it says the cable is user replaceable. What does that mean? I thought the cable was permanently attached.
Asked by: Peter
You can unscrew the back which gives access to where the cable is connected; it's a regular Thunderbolt cable plugged into a regular Thunderbolt female connector.

What is the length of the cable on this unit? Looks awfully short.

The included cable is about 20 inches long. It is not built in so you could buy a longer cable if needed.
