Small Package, Great PerformanceFusion F2QR In Hand

Mounted side by side in a tough aluminum enclosure about the size of two stacked CD cases, the diminutive Fusion F2QR contains two, 2.5-inch hard drives, with 3TB or 4TB storage capacity. Based on the multiple-award-winning Fusion F2, a portable two-drive RAID SATA storage system recognized for its performance, reliability, whisper quiet operation and shock-resistant characteristics, this compact device adds a built-in hardware RAID controller for configuring the drives, a quad interface enabling connection to almost any computer, and a greater storage capacity.

Internal Hardware RAID

A built-in high performance RAID controller manages Fusion F2QR's drives and supports RAID 0 (fast), RAID 1 (safe), concatenated (span) and even JBOD  (Just a Bunch of Disks) configurations, so you can choose the setup that best suits your needs. Whether you choose RAID 0 for the best performance, RAID 1 for a mirrored backup of your data, or JBOD to work with more audio tracks, changing the drive configuration is simple using included configuration application software. The application also provides information on the health of the drives when they've been configured as a RAID 1 set.

All the Right Connections

Fusion F2QR Back Panel PortsConnecting Fusion F2QR to your computer is simple. This portable storage system features a quad interface that requires just a single data cable to connect the enclosure to an eSATA host controller card for the fastest data transfers possible—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 2.0 cable, the drives can be accessed at the full speed of the respective interface. Sonnet even includes all the cables so you can connect your Fusion storage system right out of the box.

Fusion F2QR is powered by your computer through a spare FireWire port(2) using an included adapter cable. Alternatively, you can power the F2QR by connecting it directly to Sonnet's Qio with an optional 15cm (6") power cable. For longer fieldwork, the F2QR is also compatible with all models of myPower ALL batteries from Tekkeon at an 8-19V setting. Sonnet recommends model MP3450i, which at a 56 Watt-hour capacity, should provide up to 9 hours of F2QR run time. Other power options include another FireWire device, powered hub, or Sonnet's optional World Travel Power Adapter.

Rugged, Quiet, and Secure

Aluminum LogoFusion F2QR was devised as a high-performance, high-reliability alternative to existing portable drive solutions. Encased inside a thick aluminum shell, Fusion F2QR's drives are shock-isolated, not only protecting the drives during transport, but also virtually eliminating cross-coupled vibration—a potential source of soft-error-induced skipped frames. Fusion F2QR is cool, quiet, and energy-efficient: side-by-side placement of its drives increases the metal case's cooling surface area, thereby eliminating the need for a fan, and allowing it to be bus-powered so it can be used even when no grid power is available.

F2QR Kensington Lock PortSecure Your Fusion F2QR When Necessary. Fusion F2QR incorporates a slot for Kensington® and similar security locks to secure the system and deter theft.

Key Features

Ultra-Portable—Two 2.5" SATA drives mounted side-by-side for a total of 3TB or 4TB storage, all inside a 5.9" x 6.1" x 0.95" aluminum case and bus-powered for the ultimate in portability

Integrated Hardware RAID Controller—Supports RAID 0 (fast), RAID 1 (safe), concatenated (span) and JBOD  (Just a Bunch of Disks) configurations

Flexible Connectivity—eSATA, FireWire 800, FireWire400, and USB 2.0 interfaces enable single cable connection to most computers

Durable and Dependable—Both of F2's drives are individually shock-isolated, virtually eliminating cross-coupled vibration, which, unchecked, can induce soft errors—a potential source of skipped frames

Fast—When set to Fast mode (RAID 0) and connected via eSATA, Fusion F2QR can sustain transfer rates of up to 160 MB/sec

Complete Package—Carrying case, eSATA, FireWire 800, FireWire 800 to 400 and USB 2.0 cables included

Wide Host Controller Card Compatibility—Compatible with Sonnet's full line of Tempo PCIe and ExpressCard/34 host controllers. Also compatible with Sonnet's Qio Professional Universal Media Reader.

Cross Platform Compatibility—Supports Mac® and Windows® computers


Fusion F2QR Video Projects

Sonnet's Fusion F2QR is the perfect portable storage system for storing all your projects. With a versatile quad interface design and FireWire bus-powered operation, Fusion F2QR compliments your mobile workflow from studio to on location.


Connected to a Tempo SATA E4P eSATA adapter installed in a Mac Pro®, and with its drives configured as a RAID 0 striped volume, the compact Fusion F2QR is capable of sustained data transfers at up to 160 MB/s read and 110 MB/s write. With its drives configured as a RAID 1 mirrored volume, sustained transfers of up to 85 MB/s read and 83 MB/s write are possible, providing plenty of performance while keeping the data backed up at the same time.

Qio Companion

Fusion F2QR with QioFusion F2QR is a great matching storage solution for Sonnet's award-winning Qio Professional Universal Media Reader. Qio reads from and writes to just about any type of memory card—CompactFlash®, P2, SDHC, SxS, and SDXC—and SATA storage systems with an eSATA interface, all at high speed. Sharing the same compact footprint, the F2QR and Qio can be stacked on top of each other. You can connect the F2QR directly to the Qio using optional 15cm (6") power and eSATA data cables to keep cable clutter to a minimum.

Technical Notes

  1. Although most hard drive manufacturers and Mac OS X 10.6 define 1 gigabyte as 1,000,000,000 byte, the computer operating systems usually calculate a gigabyte by dividing the bytes (whether it is disk capacity, file size, or system RAM) by 1,073,741,824 (). This distinction may be a cause of confusion, as a hard disk with a manufacturer rating of 500GB may have its capacity reported by the operating system as 454.7GB.
  2. Powered by FireWire 400 port on computer or optional powered FireWire hub, or power out port on Sonnet Qio. May also be powered by an optional Fusion F2 World Travel Power Adapter or rechargeable battery pack.
  3. Creating RAID volumes under Windows requires dynamic disk storage, a formatting option available with Windows Server 2008 R2, Windows Server 2003 SP1, Windows 7 Professional, Enterprise or Ultimate (32- and 64-bit versions), Windows Vista Enterprise or Ultimate (32- and 64-bit versions), or Windows XP Professional (32- and 64-bit versions).
