Key Features • Four swappable drive modules equipped with 4TB Enterprise/RAID edition hard drives(1) • eSATA, FireWire 800, FireWire 400, and USB 2.0 interfaces • Single cable to host connectivity through an integrated port multiplier(2) for all interfaces • Up to 220 MB/sec transfer rate through eSATA interface (configured as RAID 0) • Drive Activity, Drive Presence, and Power LED indicators • Quiet fans • 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 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 storage systems provide mass storage in four swappable drive modules, and four ways to connect to your computer through a quad interface. Fusion D400Q offers speed, versatility, and reliability—its a great solution for anyone looking for an affordable storage system that will fit into a variety of workflows. Fusion D400Q enclosures employ a high performance SATA II port multiplier to manage the enclosed drives—just a single locking data cable connects the enclosure to a SATA 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. OS Compatibility • Platform independent—Mac, Windows(3), and 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 D400Q and R400Q storage systems require a SATA host controller that supports port multipliers, 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 or Tempo SATA Express 34 for portable computers with an ExpressCard slot. (3) Creating RAID volumes under Windows requires dynamic disk storage, a formatting option available with Windows Server 2003 SP1, Windows XP Professional (32- and 64-bit versions), or Windows Vista Enterprise or Ultimate (32- and 64-bit versions). In order to create RAID volumes larger than 2TB, you must do one of the following: Concatenate (link together in a virtual chain) the volumes, and then format them as NTFS. -OR- Use GPT formatting. Note that drives and volumes with GPT formatting are not visible to any version of Windows XP Professional, nor to the 32-bit version of Windows Server 2003 SP1.
