Superior Dual-Slot Ingest Performance

With the move to shooting demanding 8K and at high frame rates, those cards fill up faster than ever — the need for a tool that accelerates offloading footage from multiple cards is greater than ever, too. Sonnet SF3™ Series - RED MINI-MAG Pro Card Reader is the ultimate tool for the job.
