The ICY BOX IB-RD3680SU3 External RAID Enclosure gives you the ability to install up to eight 3.5″ drives inside two trayless drive cages (4 drives each) and in turn allows you to configure them either as BIG (1/2x), RAID 0 (1/2x) or RAID 5/50/10 (2x). RaidSonic has also given it both USB 3.0 and eSATA connectivity (ideal for new and older systems) along with hot-swap support, energy-saving feature for reduced power consumption when the drives aren’t accessed and two thermal controlled 80mm fans (can also be controlled manually).
