Product Overview

The EliteRAID ER104UT+ is a 4-bay hardware RAID 5 rackmount storage unit that utilizes high performance USB 3.0 and eSATA interfaces to provide over 200MB/s in performance. The included USB 3.0 is backwards compatible with the widely available USB 2.0 port, which is a convenient feature when both USB 3.0 and eSATA connections are unavailable. With built-in RAID 0, 1, 10, 3, 5+hot-spare and JBOD, the ER104UT+ provides hardware RAID redundancy protection against hard drive failures. A brand new RAID mode, CLONE or N-Way Mirror, is also introduced to replicate the saved data throughout each of the installed hard drives. The RAID engine is embedded within the enclosure and performs all RAID parity calculations to reduce CPU utilization from the host computer, RAID controller cards are no longer necessary.

The use of enterprise hard drives is recommended when in use with any RAID controller applications. Standard desktop or green desktop drive may not be supported and may compromise RAID system stability and performance
