The stylish 4 TB Mercury Elite-AL Pro Quad Interface External Dual Drive Array with RAID 0 from OWC is an external hard drive array that utilizes two high-capacity, high-performance hard drives and offers superb data transfer speeds. This enclosure contains two Hitachi Deskstar 7K3000 2.0 TB hard drives that spin at a swift speed of 7200 rpm, have a fast 6.0 Gbps SATA drive interface, and boast a total storage capacity of 4.0 TB. They also each boast a 64 MB buffer. The drives come preconfigured as a RAID 0 array, so that you can experience maximum data transfer performance from this array. In addition, this array utilizes an Oxford 944 Bridge chipset for increased speed.
RAID, or Redundant Array of Independent Disks, is a system that stores the same data on different drives, so that if one drive fails, you don't lose all your data. RAID 0, essentially 'No RAID,' also known as Striping Mode, allows for maximum performance as data is "striped" across the drives, using the full speed of the individual hard disks. This setting offers no redundancy and, thus, little protection against data loss, but it maximizes usable drive capacity.
For connecting the drive to your computer, you have numerous options. You can use one of two built-in FireWire 800 ports, the eSATA port, the FireWire 400 port, or the USB 2.0 port. The USB 2.0 port is also backwards compatible with computers that have older USB ports. You can transfer data at speeds up to 3.0 Gbps via the eSATA port, 800 Mbps via the FireWire 800 port, 400 Mbps via the FireWire 400 port, and 480 Mbps via the USB 2.0 port.
This external hard drive array comes formatted for Mac computers and is plug-and-play via the USB 2.0 port; however, you can reformat the drive to work with Windows as well. While you can easily use it to store additional files or backup your hard drive, you can also use it as an external boot drive for your Mac or Windows computer. Along with the drive, you'll receive the following software: Intech's Hard Disk SpeedTools Utilities, Prosoft's Engineering Data Backup, NovaStor's NovaBACKUP, Carbon Copy Cloner, and over 1.5 GB of other free programs.

| Boot Requirements |
Below are the requirements for using the drive as an external boot disk. eSATA General Requirement for either Mac or Windows Computers: Bootable eSATA host controller Mac: Built-in: Any SATA based Mac using a built-in SATA connection adapted to an eSATA connection will support booting. Port multiplier enclosures are not supported. Card/HBA: Most eSATA expansion cards or host board adapters will not be bootable. Check with your specific card manufacturer regarding Mac boot support. PC: Will boot as long as your BIOS supports booting from the eSATA interface. BIOS support will vary by motherboard and host board adapters. FireWire 800 Boot/Startup Mac: Intel Macs and some PowerPC Macs running OS 8.6 or later. Please note, non-Intel Macs will not be able to boot external enclosures that have over 2.2 TB support enabled. This is a hardware limitation of the computer. PC: Will boot as long as your BIOS supports booting from the FireWire 800 interface. BIOS support will vary by motherboard and host board adapters. FireWire 400 Boot/Startup Mac: Intel Macs and some PowerPC Macs running OS 8.6 or later. Please note, non-Intel Macs will not be able to boot external enclosures that have over 2.2 TB support enabled. This is a hardware limitation of the computer. PC: Will boot as long as your BIOS supports booting from the FireWire 400 interface. BIOS support will vary by motherboard and host board adapters. USB 2.0 Boot/Startup Mac: All Intel Macs. Unofficial support exists for various PowerPC models running OS 8.6 or later, but OWC cannot guarantee any particular boot support. Please note, PowerPC Macs will definitely not be able to boot external enclosures that have over 2.2 TB support enabled. This is a hardware limitation of the computer. PC: Will boot as long as your BIOS supports booting from the USB 2.0 interface. BIOS support will vary by motherboard and host board adapters. |

Comments about OWC / Other World Computing 4 TB Mercury Elite-AL Pro Quad Interface External Dual Drive Array with RAID 0:
This drive works perfect but to use this on xp you have to set the jumpers inside of the array to use both individual 2TB disks. windows7 it will work as a perfect 4TB one large drive. and because of the XP issue i only gave 4stars.

Comments about OWC / Other World Computing 4 TB Mercury Elite-AL Pro Quad Interface External Dual Drive Array with RAID 0:
This would be a five star rating if the actual capacity was closer to 4 TB. Out of the box, the capacity is 3.6 TB. That's not a huge complaint. You can't expect to access the full capacity of any hard drive. Still, for such a quality product it's hard to beat the price.
