This is the RAID storage solution I have been asking for and waiting years to get! It's a two drive external RAID with Thunderbolt 3 connectivity that also has built in card readers! YAY!!
2big Dock can be easily configured for Windows or Mac, in RAID 1, 0 or JBOD, using LaCie's excellent RAID manager tool. Because it is Thunderbolt 3, it also supports USB-C, USB3 and USB2, so you can connect it to any computer you own. The throughput will vary based on connectivity. With Thunderbolt 3 in RAID 0 you get a blazing fast 440 megabytes per second throughput. More than fast enough for all HD workflows and most compressed 4K formats.
The 2big Dock includes an SD card and compact flash reader. It also gives you a USB3 port and display port, making it a must have storage solution for laptop based digital photographers and video editors. In the future I'd love to see a version with more professional readers like CFast or XQD. Starting at $649 for an 8TB model it's pretty affordable, but I think the 12TB for $799 and 16TB for $999 are much better values. While the 20TB for $1,199 is a great investment for those who need massive amounts of storage.
