LaCie, which is now part of the Seagate house, has released a new version of its Little Big Disk storage unit that's claimed fast enough to enable simultaneous plug-and-play RAW 4K video editing and display. The device boasts a terabyte of onboard storage, two Thunderbolt 2 ports, and near silent dual cooling performance.

LaCie says that the Little Big Disk's interior design has been optimized to improve cooling efficiency, adding two aluminum heat-sink plates to help reduce the unit's dependence on the integrated thermoregulated, whisper quiet fan. It features two 500 GB PCIe Gen 2 SSDs in a RAID 0 configuration (which can be configured to RAID 1 or JBOD if desired), and two Thunderbolt 2 ports for interface transfer rates of up to 20 Gb/s.

The company is claiming transfer speeds of up to 1,375 MB/s (read) and 1,180 MB/s (write), and connecting two storage units in parallel to the new Mac Pro is said to boost transfer speeds up to 2,600 MB/s. Up to five units can be daisy-chained (plus a 4K monitor on the end of the chain), and the drive unit will work with first-gen Thunderbolt technology, that first arrived on the company's Little Big Disk in 2011.

Though described as portable due to its 1.6 x 5.5 x 3.3 in (40 x 140 x 85 mm) dimensions and weight of just 1.4 lb (620 g), the new Little Big Disk, which includes AES 256-bit software encryption to help keep your data safe, will still require users to be near a 110/240 V power outlet to run the storage unit.

The Little Big Disk Thunderbolt 2 is available in 1 TB SSD capacity for a suggested starting price of US$1,299.99.
