The Mercury Elite-AL Pro Qx2 is a quad-interface RAID, equipped with FireWire 800, FireWire 400, USB 2.0 and external Serial ATA (eSATA) ports. It also features four SATA hard disk drive bays and four user-selectable hardware RAID settings.
Equipped with 2TB SATA hard drives in each bay, the Mercury Elite-AL Pro Qx2 can hold up to 8TB of storage and can achieve data transfer speeds of up to 300 megabytes per second, according to OWC. The front-panel LEDs give you at-a-glance system status and the drive bays can be locked behind a removable key lock. The front panel selector switch lets you choose between four hardware RAID settings: 0, 1, 5 and 10, as well as a “span” or NRAID setting.
