Product Description

CompactFlash to the Power of Four

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 2.0 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 USB 2.0 adapters are capable.

Choice of Interface

Qio CF4 is available with your choice of a PCIe interface card for desktops, an ExpressCard/34 interface for notebooks, or a Thunderbolt interface adapter (with included Thunderbolt cable) for any Mac with a Thunderbolt™ port. With the purchase of an additional Qio CF4 PCIe adapter card, ExpressCard/34 card, or Thunderbolt adapter, you can move your Qio CF4 from suite to suite, and then to location and back again without breaking a sweat. No matter where you use it, Qio CF4 will quickly become an essential tool in your workflow.

Mac and Windows Compatible

Sonnet’s Qio CF4 offers cross-platform compatibility, extending its usefulness on location and in the studio. Whether you’re using a MacBook Pro®, HP Z800 or Mac Pro®, or any Mac with a Thunderbolt port, the Qio CF4 fits seamlessly into your workflow.

6Gb/s SATA PCIe 2.0 Host Controller Inside

Qio includes two 6 Gb/s eSATA ports, perfect for connecting media readers with an eSATA interface, such as the RED STATION REDMAG 1.8″ and 2.5″.

Travel and Desktop Companion

This Sonnet pro media reader is small—about the size of three stacked CD cases—and takes up so little space, you can use it just about anywhere. It’s rugged, too—the robust aluminum case easily withstands heavy use. For desktop use, a universal 12V output AC power supply with wall plugs for US, Japan, Europe, UK and Australia use is included. For battery-powered operation, an optional XLR 4-pin adapter cable can route battery power to the Qio CF4. This pro media reader even incorporates a Kensington® slot for to secure the device and deter theft.
