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. 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). Its USB 3.0, eSATA, and dual FireWire® 800 ports provide you flexibility in connecting the system to just about any computer. The QR even includes a built-in carrying handle to make this rugged and lightweight system highly portable. 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(1) 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.
