The Sonnet card reader can ingest files simultaneously from two CFexpress cards at up to 2,600 MB/s (or two XQD cards at up to 800 MB/s). This can cut ingest times by up to half compared to any USB- or Thunderbolt-based single-slot reader available.

The Sonnet’s SF3 Series – CFexpress / XQD Pro Card Reader is the only dual-slot CFexpress 2.0 Type B card and dual-slot XQD card reader available, and it supports both card types in both slots. For DITs working multicamera shoots or in a small workspace, the ability to stack multiple SF3 Series CFexpress / XQD, RED MINI-MAG, SxS, and CFast 2.0 readers in the same footprint is convenient, and you can do all this by connecting them all to a computer through a single cable.
