Looking for an affordable desktop multi-drive storage system? Sonnet’s Fusion QR should be on your short list. This versatile 4-drive RAID 5 SATA storage system delivers reliable operation, simple configuration, and flexible connection options in a small, budget-friendly package. Available without drives, and in 8TB, 12TB, and 16TB configurations(1), this Sonnet storage system is equipped with a high-performance internal storage controller that manages the enclosed 3.5″ hard drives and offers five drive configuration options (including RAID 5).

The QR even includes a built-in carrying handle to make this rugged and lightweight system highly portable.

Key Features

Protected Data—RAID 5 support offers enhanced security for your critical files, providing data protection in case one of the drives fails

RAID Controller Onboard—Integrated hardware RAID controller supports RAID 5, RAID 0, RAID 10, JBOD, and span drive configurations with no specialized controller card needed

Quad Interface—Choice of USB 3.0, dual FireWire 800, and locking eSATA interfaces; three cables included

Simple Configuration—A simple switch enables you to select RAID modes and configure the drives to meet your performance and data security needs

Simple Status Display—Determine operating status at a glance

Highly Portable—Rugged and lightweight enclosure with built-in handle allows the QR to be picked up and moved easily and securely

Quiet Fan—Low fan noise level makes this Fusion storage system suitable for use in noise-sensitive environments



RAID 5 Controller OnboardHardware-Based RAID 5 Storage Controller Onboard

The Fusion QR’s integrated storage controller supports RAID 5 formatting without additional hardware or software, providing data protection in the event of a single drive failure and eliminating the need for a specialized RAID controller card. In addition to RAID 5, the QR supports RAID 10, Span, and JBOD(2) drive formatting. With RAID 10, two drives are combined into a single volume, while the remaining two drives mirror the data on the first two, providing good performance and better file security. Span formatting combines all four drives’ capacity into a single, large volume.  The JBOD (Just a Bunch Of Disks) formatting option enables more concurrent audio file editing capabilities. Whichever mode you choose, setup is as simple as setting a switch. Drive operation and health status is available at a glance with multi-color LEDs.

Choice of Connections

Connecting the Fusion QR to your computer is simple. This storage system features a quad interface that requires just a single data cable to connect the enclosure your computer, simplifying setup and cutting cable clutter without compromising performance. The USB 3.0 port enables you to connect the system to nearly any computer equipped with USB ports. The eSATA port allows you to connect to computers with eSATA controller cards, and it supports Sonnet’s exclusive locking eSATA cables that prevent accidental cable disconnection. FireWire 800 connectivity is provided to support older computers. For your convenience, Sonnet includes the cables for each interface (USB 3.0 with standard full-size A and B connectors, FireWire 800, and eSATA with Sonnet-exclusive locking connectors) so you don’t need to buy a new one or search for a spare. In case you want to use an interface your computer lacks, Sonnet offers a wide variety of PCIe, ExpressCard, and PCI computer cards to get you connected.

Compact, Rugged & Portable

The Fusion QR is compact—it’s not significantly larger than the four hard drives it holds. Its outer enclosure is made of extruded aluminum, making it lightweight, yet rugged. A large, built-in carrying handle makes the QR easy to carry, but for times when you prefer to keep it in place, the QR incorporates a slot for Kensington® and similar security locks to secure the system and deter theft.

Large Quiet FanQuiet Enough to Sit Beside You

To keep things cool, the Fusion QR uses an external power supply, allowing the use of a single, large fan to cool the drives. The fan runs quietly, make the QR suitable for use in many noise-sensitive environments, too.

Driving Force

The Fusion QR storage system employs Sonnet-certified desktop drives 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 become the building blocks of a super-reliable Fusion storage system.

Versatile Performance

The Fusion QR delivers data transfers up to 250 MB/sec read and 240 MB/sec write with its drives configured as a RAID 5 group. The flexibility and interoperability that the QR provides are a great match for the various operating systems, applications and output demands your workflow requires. Because this Fusion storage system uses an integrated storage controller, it supports Mac®, Windows®, and Linux® computers, no configuration software required.

Checkmark IconCustomizable Storage Option

Looking for a storage system that is more closely tailored to your needs, one with a lower storage capacity, for instance? Choose the Fusion QR 0TB—you purchase the drives that best suit your capacity and performance needs, and then install them yourself.

Technical Notes

  1. Although hard drive manufacturers and Mac OS X 10.6 define 1 gigabyte as 1,000,000,000 byte, many other computer operating systems calculate a gigabyte by dividing the bytes by 1,073,741,824 (). This distinction may be a cause of confusion, as a hard disk with a manufacturer rating of 1000GB may have its capacity reported by the operating system as 915GB.
  2. When connected to your computer via eSATA, JBOD formatting requires the use of a SATA host controller with port multiplier support.
