The Sonnet SF3 AJA PAK Media Pro Card Reader is built for professional media workflows — fast, compact, and certified by AJA. Whether you're capturing multi-cam events or 4K footage on an AJA Ki Pro Ultra 12G, this Thunderbolt 4/3 reader lets you offload your footage at lightning speed — up to 1030 MB/s aggregate.
With dual card slots, you can ingest from two AJA PAK media cards at once, cutting your workflow time in half. Need more power? Daisy chain up to six readers for simultaneous six-card ingest — without swapping or pausing.
