LaCie says its Little Big Disk, featuring Thunderbolt 2, is the fastest portable external storage solution ever. We won't argue as it delivers speeds up to 1,375 MB/s and fits in a laptop bag.

Thanks to its two Thunderbolt 2 ports, the LaCie Little Big Disk can be daisy chained with other devices. Professionals can daisy chain up to five LaCie Little Big Disks plus a 4K display, and connect them to a computer via a single cable. These features offers professionals a portable solution for editing 4K video in the field.

To achieve the full potential of Thunderbolt 2 speeds, LaCie engineered the Little Big Disk with a pair of 500 GB PCIe Gen 2 SSDs. It's possible to push the boundaries of the technology even further by daisy chaining two LaCie Little Big Disks to achieve speeds faster than the maximum Thunderbolt 2 transfer rate. By connecting them in parallel to Apple's new Mac Pro, they can deliver speeds up to 2,600 MB/s.

In addition to its post-production benefits, the LaCie Little Big Disk can transfer dailies ten times faster than any mobile USB 3.0 hard drive. For example, it's possible to transfer 300 GB of 4K footage in less than three minutes, saving hours a day.

Including high–performance SSDs and interface meant LaCie had to optimize the Little Big Disk's interior design to improve cooling efficiency, while simultaneously reducing noise. The company added two heat–dissipating aluminum plates in addition to a larger, thermoregulated fan. This means that the fan only turns on when necessary, and when it does, it produces nearly zero noise.

The new Little Big Disk, featuring Thunderbolt 2, is available in 1TB SSD capacity through the LaCie Online Store and LaCie Resellers starting at US$1,299. Thunderbolt 2 is compatible with the same cables and connectors as first–generation Thunderbolt. Go to www.lacie.com for more info.
