4.0TB OWC Mercury Elite Pro Qx2 eSATA,FireWire 800+USB 2.0 1U 4-Bay SATA Desktop RAID Solution with selectable RAID 0,1,5,10 Hardware RAID Mode, NRAID Span Options. Oxford 936 chipset, 3 Year Warranty.

Four 3.5" Serial ATA (SATA I/II) hard disk drives in a brushed aluminum enclosure with Hardware RAID setting flexibility and up to 300MB/s data transfer speed for high performance data storage and redundancy.

Thanks to a front panel selector switch, the Mercury Elite-AL Pro Qx2 enables easy configuration of the Hardware RAID settings - NRAID, 0, 1, 5, 10 - so you can select the best combination of speed, capacity, redundancy, or any combination of the three.

  • NRAID (Span): Combines capacity of two or more drives of the same size without any RAID data distribution scheme into one logical desktop volume. Will also 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.
  • RAID 1 (Mirror): Data is written at same time to two drives only 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 of speed, capacity, and redundancy. The "Quad 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.

Time Machine ready means that OWC's external hard drives keep an up-to-date copy of all of your files and documents under OS X Leopard™.
