More Info

The Mercury Elite Pro Dual mini Quad Interface RAID Enclosure is an exceptional way to create your own high-capacity, high-performance external storage out of any SATA 2.5" internal hard disk or solid-state drives. This enclosure can hold two of these drives of up to 12.5mm in size. It supports RAID 0, 1, and NRAID (or spanning) and can also be used as an external boot drive.

In terms of connecting to your computer, this enclosure features four different interfaces. At your disposal, you will have two FireWire 800 ports, one FireWire 400 port, one eSATA port, and one USB 2.0 port. With the eSATA port, you can transfer data at a speedy rate of up to 300MB/s. Also, with the FireWire 800 port, you can power the enclosure.

Beyond these ports, this enclosure is shock-resistant, near-silent and fanless in operation. While it comes formatted for Macs and is Time Machine and Mac OS X 10.6 Snow Leopard ready, it can also be reformatted to work with your Windows or Linux computer system.

Includes two FireWire 800 ports, one FireWire 400 port, one USB 2.0 port, and one eSATA port 1
With the eSATA port, you can transfer data at up to 300MB/s. With either FireWire 800 port, you can transfer data at up to 100MB/s. With the FireWire 400 port, you can transfer data at up to 50MB/s. With the USB 2.0 port, you can transfer data at up to 60MB/s
The enclosure supports hardware RAID Modes: 0, 1, and NRAID (Span)
During RAID 0 (Stripe), data is split into blocks over two or more drives at same time for high speed and large capacity
During RAID 1 (Mirror), data is written at same time to two drives only for highest level of data safety and redundancy
With NRAID (Span), you can combine the capacity of two or more drives of the same size into one logical desktop volume without any RAID data distribution scheme. This will also combine the capacity of varying size drives based on the lowest capacity drive in the set

Boot Requirements Below are the requirements for using the enclosure (and separately-purchased drives within it) as an external startup drive.

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 2.2TB 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 2.2TB 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 2.2TB 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.
Power Requirements Bus power via FireWire 800 supported on all models equipped with an available FireWire 800 port either factory stock or via add on FireWire 800 PCI Card

Note: eSATA connection requires FireWire bus power or external power supply and USB port requires external power supply

Note: AC adapter not required for most applications provided computer bus supplies appropriate power needs
