Configured with SATA drives, these systems are designed to provide a low-cost entry point for small to medium size businesses without sacrificing scalability or functionality. Transitioning from the entry-level to the midrange, the DS4300 includes three options; a single controller unit, dual controller unit, and dual controller unit with Turbo features. These three disk systems are based on the same controller and offer users high-end functionality, integrated data replication services, and a choice of FC or SATA drives to best meet their requirements. Squarely in the midrange is the DS4700 Express model. This fully-featured disk system is based on 4 gigabit per second Fibre Channel technology and provides outstanding connectivity, exceptional performance value, high-end functionality, integrated data replication services, and scalability up to 112 FC or SATA drives. With 2 distinct offerings, the DS4700 Express is right at home fulfilling energetic departmental workloads or the requirements of the storage area network. At the upper end of the midrange is the DS4500. This field-proven disk system offers scalability up to 224 FC or SATA disk drives and can still deliver more disk-based IOPS than most competitive systems. As the new flagship system in the DS4000 series, the DS4800 is a true industry leader. From its full 4 gigabit per second Fibre Channel design to its industry-leading performance, the DS4800 is unrivaled among modular storage sys
