Key Features • Four swappable drive modules equipped with 2TB Sonnet-certified desktop hard drives(1) • High Performance, Protected Data • RAID 5 Onboard—Integrated hardware RAID controller supports RAID 5 drive configuration on its own; no need for a specialized RAID controller card • Four Interfaces, Single Cable Connection—Choose from eSATA(2), FireWire 800, FireWire 400, and USB 2.0 interfaces, and connect to your computer with a single cable • Informative Display and LED Indicators—Provide operating status at a glance • Simple Configuration—Integrated controls enable you to select RAID modes and configure the drives to meet your performance and data security needs, no matter which interface you choose • Quiet Fans—Low fan noise levels make these Fusion storage systems suitable for use in noise-sensitive environments • eSATA, FireWire 800, FireWire 400 and USB cables included • Compatible with Sonnet Tempo™ SATA II PCI-X, PCIe, and ExpressCard/34 host controllers • RoHS compliant Performance and Data Security Considering a multi-drive storage system? If so, you already know about the benefits of striping data across multiple drives—you’ll gain the faster performance necessary for working with HD video formats when you connect the system to an eSATA host controller. Sonnet’s Fusion™ D400QR5 desktop SATA storage systems deliver speed, reliability, and versatility in easy to deploy packages. Fusion D400QR5 systems offer security, too—each one features a high performance internal RAID controller that manages the enclosed drives and supports RAID 5 drive formatting, which provides data protection in case one of the drives fails. Fusion D400QR5 storage systems incorporate an informative display and status LEDs, and simple to use controls that enable you to easily configure the drives or select information to be displayed. OS Compatibility • Mac OS X • Windows Vista Ultimate/Enterprise • Windows XP 64-bit(3) • Windows Server 2008 • Windows Server 2003 • Linux Technical Notes (1) Although most hard drive manufacturers 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) When connected to a computer via its eSATA interface, Fusion D400QR5 and R400QR5 storage systems perform their best when used with a high performance SATA host controller such as Sonnet's Tempo SATA E4P for computers with PCI Express slots, Tempo SATA X4P for computers with PCI-X slots, or Tempo SATA Pro ExpressCard/34 for portable computers with an ExpressCard slot. (3) Windows XP 32-bit (most versions of Windows XP are 32-bit) does not support volumes greater than 2TB. Windows XP x64, Windows Vista Ultimate/Enterprise (32-bit and 64-bit editions), Windows Server 2003 and Server 2008 support volumes greater than 2TB, but must be formatted using the GPT file system, which is not accessible by Windows XP 32-bit.
