OWC Mercury Elite Pro Qx2

4-bay add your own drives enclosure kit

Mac / PC / USB 3.0 & 2.0 / FireWire 800 (FireWire 400 Backwards Compatible) / eSATA
The Ultimate Blend of Professional
Performance and Convenience
Install your own set of four matched (same part number) 3.5" Serial ATA (SATA I/II) hard disk drives into this brushed aluminum enclosure with Hardware RAID setting flexibility and experience up to 300MB/s data transfer speed for high performance data storage and redundancy.
User-Selectable Hardware RAID Settings
Thanks to a front panel selector switch, the Mercury Elite Pro Qx2 enables easy configuration of the hardware RAID settings to Span, 0, 1, 5, 10, and JBOD/Independent drive modes – so you can select the best combination of speed, capacity, redundancy.
Combines the capacity of two or more drives of the same size without any RAID data distribution scheme into one logical desktop volume. This mode can combine the capacity of varying size drives based on the lowest capacity drive in the set.
RAID 0 (Stripe)
Data is split into blocks over two or more drives at same time for high speed and large capacity. The ideal RAID setting for demanding video production/editing.
RAID 1 (Mirror)
The same data is written to two drives for highest level of data safety and redundancy.
RAID 5 (Stripe with Parity)
Data is Striped (RAID 0) while incorporating redundancy over three or more drives for the best combination for speed, capacity, and redundancy. The Multi-Interface 4 Bay Enterprise Class Performance RAID Solutions are pre-configured as RAID 5.
RAID 10 (1+0)
Data is Striped (RAID 0) over two Mirrored sets (RAID 1) of drives for fast redundancy.
JBOD/Independent drive operation
Each drive mounts as an individual volume.
Uses four 3.5" SATA hard drives
(Drives not included)

A 'recommended' drive is one that, through our extensive and ongoing evaluation process, we've found to have optimum operational characteristics required for demanding RAID applications.

Note: OWC is always testing new drive models and adds additional models as they become available and have passed our stringent requirements. If you do not see a new drive model listed, please check back in the future for confirmed OWC Qx2 Qualification.

Note: Regardless of drive model used, OWC requires that all drives used match exactly for proper RAID operation.

OWC strongly recommends against use of any 7200.11 HD in the Qx2 Solution due to inconsistencies in 7200.11 firmware sets and general long term stability concerns. Seagate 7200.11 Drives do not meet OWC QX2 Qualification.
