A variety of RAID modes are supported, which help provide users with data redundancy, speed, or a combination of both. Supported RAID modes include RAID 0, 1, 5, 6, 10, Basic, and Synology Hybrid RAID. For those who do not require a RAID, JBOD is also available, allowing each drive bay to be individually utilized.

ioSafe has engineered this NAS to be energy efficient. Not only does it use dual 80 x 80mm fans to help keep the system running cool, the server supports numerous scheduled power on / off cycles and hard drive hibernation to further minimize power consumption and operational expenses.
