This week, LaCie took the wraps off what they’re calling the “World’s Fastest” portable external hard drive.

The new model, named the LaCie Little Big Disk, featuring Thunderbolt 2 pushes 4K video files around faster than it takes to say the product name. Well, not quite, but with read/write speeds approaching 1,375 MB/s we’re not too far away.

LaCie, now fully owned by storage giant Seagate, achieve the speeds quoted by pairing their Little Big Disk with high–performing solid state drives – a pair of 500 GB PCIe Gen 2 SSDs. According to the company, performance can be pushed even further by daisy-chaining two Little Big Disks together to achieve speeds faster than the maximum Thunderbolt 2 transfer rate. Tests conducted by LaCie with two Little Big Disks connected in parallel to Apple’s  new Mac Pro saw speeds up to 2,600 MB/s.

Positioned for video professionals, up to five  Little Big Disks plus a 4K display can be daisy-chained simultaneously and connected to a computer via a single cable.

Expect pricing to be as premium as the Little Big Disk’s performance, with 1TB SSD capacity starting at $1299.
