Product Description

CompactFlash to the Power of Four

4 CompactFlash Cards CompactFlash (CF) memory cards are rugged, offer high storage capacities, and can deliver fast data transfers; that’s why HD camcorders from RED® and Canon®, as well as DSLR cameras from Canon and Nikon® use them. Even as the card specs have improved, moving ever-larger files from from cards to computer has remained mostly a low speed affair. If you have ever ingested files from CF cards, you know what we mean. Plug in the camera or a USB reader, grab a cup of coffee, and relax while all those gigabytes of data are transferred at around 30 MB/s. But what if you need faster transfers? Or want to ingest files from more than one card at a time? Sonnet’s Qio CF4 is the answer to all of these questions.

This Sonnet pro media reader distills the feature set of the award-winning original Qio universal media reader, and is designed specifically for use with CF media cards. Providing a cost-effective, high-speed multi-slot alternative to stand-alone card readers for pro videographers and photographers alike, Qio CF4’s four CF slots enable you to ingest files faster and more efficiently, with aggregate ingest speed up to 400 MB/sec., much faster than standard USB adapters are capable.
