The LaCie 2big 2-Bay Thunderbolt 2 RAID Array has two hot-swappable bays that each contain a 6TB 7200 rpm hard drive for a total storage capacity of 12TB. For connectivity, the 2big has a USB 3.0 port as well as two Thunderbolt 2 ports, so you can daisy chain it with other Thunderbolt 2 devices. The drives are preconfigured in HFS+ for Mac systems and in RAID 0 for performance up to a max speed of 420 MB/s. For security, it's compatible with Kensington locks, and is cooled thanks to a built-in fan.
