Qio CF4 with Sonnet Bus Extender PCIe Adapter

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 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 but 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.
Mac, Windows & Thunderbolt™ Compatible
Sonnet's latest professional media reader 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, Qio CF4 fits seamlessly into your workflow. Using a Mac with a Thunderbolt™ port? Qio CF4 is compatible with Thunderbolt technology and performs at maximum speed when connected with Sonnet's Echo™ ExpressCard Pro Thunderbolt Adapter, xMac™ mini Server, Echo Express, or Echo Express Pro Thunderbolt Expansion Chassis, expanding the reach of Qio CF4's benefits to more even more computers than before.
6Gb/s SATA PCIe 2.0 Host Controller Inside
Qio CF4 incorporates two eSATA connectors on the back to enable you to connect two Sonnet Fusion™ F2QR portable 2-drive hardware RAID SATA storage systems, or other SATA storage to easily ingest files in the field.
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. Sharing the same 15cm (5.9") by 16cm (6.2") footprint as the Fusion F2QR storage system, the case measures just 2.5cm (1") tall. It's rugged, too—the robust aluminum case 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; it's capable of powering the Qio CF4 plus an attached F2QR. For battery-powered operation, an optional XLR 4-pin adapter cable can route battery power to the Qio CF4 plus one attached Fusion F2QR.
