Supports CFast 2.0 Cards at Maximum Speed

Superior Dual-Slot Ingest Performance

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. With current CFast 2.0 cards’ rated read speeds near 550 MB/s, it’s clear that USB readers don’t fill that need. Sonnet’s SF3™ Series - CFast 2.0 Pro Card Reader does. Equipped with a high-bandwidth Thunderbolt™ interface, this professional media card reader enables ultra-fast transfer of footage from CFast memory cards to Apple M series Macs, Intel Macs with Thunderbolt 3, and Windows PCs with Thunderbolt 4 or 5 — delivering speeds as fast as the cards allow.
