The optimum combination of mega storage capacity, SATA speed and superior RAID security, this powerful RAID comes in a 4-bay array with hot-swappable hard disks and hardware RAID controller. Preconfigured at RAID 5, it supports RAID levels 0, 0+1, 5 and RAID 5+hot spare, and offers automatic background rebuilding (in RAID 5). Its SATA interface provides a speedier boot process and faster loading of programs and data and even simpler cabling, enabling rapid sustained transfer rates of up to 80MB/s. Ideal for saving hefty files, protecting databases or working directly on the drive, it delivers high-capacity performance at a comparatively low cost.
