The 8big Rack's innovative cooling system prolongs component lifespan, featuring three efficient, thermoregulated cooling fans to drive airflow. A metal sheet beneath the disks dissipates heat, and cool air flows under the sheet to drain hot air away. Above and between the two rows of disks, air flows from front to back, conducting heat away from sensitive components.The Most Powerful I/O, Reinvented Thunderbolt technology redefined external storage with its speed and versatility for bandwidth-intensive applications. Thunderbolt 2 builds on those advances by doubling the speed potential to 20Gb/s and enabling simultaneous RAW 4K video editing and display. And thanks to support for DisplayPort 1.2, it's now possible to daisy chain higher-resolution displays such as 4K monitors. In addition to higher performances, the Thunderbolt 2 I/O offers dramatically simpler connections than Fibre Channel. Connect the LaCie 8big Rack to a computer via the Thunderbolt cable - no HBA (host bus adapter) necessary - and instantly the volume mounts on your OS. And unlike Fibre Channel, Thunderbolt 2 is truly a plug and play and single-vendor solution. No port mapping or multipathing is required to achieve this performance. Thunderbolt technology even supports optical cables, which means you could connect a LaCie 8big Rack to a computer located up to 60 meters (197 feet) away.
