Multiple Drives, No Compromise

Digital content creation and editing requires more speed and space than standard desktop drives are capable—why limit yourself to a single drive? Sonnet’s award-winning Fusion™ D400Q desktop and R400Q rackmount storage systems (except 0TB models) provide up to 8TB(1) of storage in four swappable drive modules, and four ways to connect them to your computer. They offer speed, versatility, and reliability—they’re great solutions for anyone looking for an affordable storage system that will fit into a variety of workflows.

One Cable, All the Data

Fusion Enclosure Back PanelFusion D400Q and R400Q enclosures employ a high performance SATA II port multiplier to manage the enclosed drives—just a single locking data cable connects the enclosure to an eSATA host controller card. This efficient interface simplifies setup and cuts cable clutter without compromising performance. No SATA? No problem—connected via a single FireWire® 800, FireWire 400, or USB cable, all four drives can be accessed at the full speed of the respective interface. There is no need to reformat drives when changing from one interface to another, regardless the configuration.

Maximum Performance, Maximum Convenience

Connected to a Sonnet Tempo™ SATA E4P PCIe or X4P PCI-X host controller installed in a Mac® or Windows® computer, a Fusion D400Q or R400Q system’s drives can be accessed through its port multiplier(2) at maximum speed, whether configured as a RAID 0, 1, 10, or JBOD set. With its drives configured as a RAID 0 striped set, a single Fusion D400Q or R400Q system achieves data throughput of 220MB/sec, fast enough to support multiple streams of DV, HDV, DVCPRO, ProRes 422, or a single stream of uncompressed 10-bit NTSC video. Do you want even more performance? Up to four Fusion D400Q or R400Q systems can be ganged on a single Tempo SATA E4P or X4P controller for enhanced data throughput and multiple times the available streams (as well as increasing the number of supported video formats).

Driving Force

Fusion storage systems (except 0TB models) employ Enterprise/RAID Edition hard drives or select, Sonnet certified desktop drives(3) that have been selected for their superior performance, error handling, and reliability characteristics, especially when used in RAID groups. These drives are subjected to hours of additional, stringent testing to check for soft errors, vibration, and other reliability predictors. Just the sturdiest drives pass these tests and are prepared with special RAID-optimized firmware to become the building blocks of a super-reliable Fusion storage system.

Versatile Performance

These systems are ideal for use in mixed environments—various operating systems, editing applications and output demands requiring the flexibility and interoperability that Fusion D400Q and R400Q storage systems provide. Fusion storage systems support Mac OS® X, Windows® 7, Windows Vista®, Windows XP, Windows Server 2008 and 2003, and Linux. They are compatible with capture cards from AJA, Blackmagic Design, Matrox, and Bluefish444, and work with all mainstream video editing applications including Apple® Final Cut Pro®, and Adobe® Premiere® Pro.

Desktop or Rackmount

To keep things cool, the Fusion D400Q uses a swappable fan module. The fan is 80% quieter than a standard case fan, making this system perfectly suited for use in noise-sensitive environments. The 1U rackmount Fusion R400Q system enclosure, at just 1.75" tall, is simple to deploy in most server racks. Both systems feature drive presence and drive activity LED indicators on their front panels, so drive status can be determined at a glance.


Fusion D400Q storage systems integrate an ultra-quiet, user-swappable fan module using the Vantec Stealth™ fan. This fan is 80% quieter than a standard case fan, making this system perfectly suited for use in noise-sensitive environments.

Secure Connection
Fusion D400Q and R400Q enclosures link to Sonnet Tempo SATA E4P and X4P SATA host controller cards with Sonnet's exclusive locking eSATA data cables with connectors that lock securely at both ends.

Expandability to Start

Looking for a desktop or rackmount 4-drive, removable storage system to expand with your needs? Fusion D400Q-0TB and R400Q-0TB storage systems offer the same great features as Sonnet’s other D400Q and R400Q models, but without the hard drives(3). Of course performance, capacity, and RAID reliability are dependent on drive choice.
