Somewhere between a desktop media drive and a portable storage unit, the Fusion F2 comprises two 2.5in eSATA drives bolted together in a rugged chassis.
Pitched at video editors, VFX and motion-graphics artists, and animators, the Sonnet Fusion F2 is an innovative but pricey device that's in essence two 2.5in eSATA drives bolted together in a rugged chassis, with power provided by a FireWire lead.
The standard set-up for the slick, matte silver Sonnet Fusion F2 requires you to connect the device to your MacBook Pro or Windows laptop over two eSATA cables, using an ExpressCard plug-in card such as Sonnet's Tempo SATA ExpressCard/34.
You then plug the power lead into the laptop's FireWire port and set up the drives as a striped or mirrored device using Mac OS X's Drive Utility, or as a striped array using Windows Administrative Tools (as only the server versions of Windows support creating RAID 1 arrays in software).
The Sonnet Fusion F2 uses the FireWire's power output, and is designed to be used alongside AJA's Io external capture and effects box - which requires all of the FireWire bandwidth to itself - to create a full Final Cut Studio edit suite around a MacBook Pro.
The innovative set-up enables you to create a floating edit suite: you can edit on the road just using your laptop and Sonnet Fusion F2, then plug in an LCD screen, decks and other hardware boxes such as the Io for a full-powered studio. As it uses a software RAID, it's not practical to swap the F2 between desktop and laptop edit suites.
The Sonnet Fusion F2 is a niche device but if you regularly edit on location or in transit, it's going to be highly useful. For example, Sonnet has made much of the F2 being used for editing Iron Maiden's recent tour diaries between gigs.
