LaCie has updated their 2big dock for desktop creators. This device can hold up to 20TB in a RAID or Mirror format. Compact Flash, SD, USB-A, Dual USB-C (TB3 rated), and Display Port connections so you can dock devices for file transfer, viewing, and more.
If you need to go backwards compatible with Thunderbolt 2, you will have to get the Apple Adapter ($49). For content creators, this can allow you to hold over 650 hours of 4K video. You can also chain another 2big to add even more storage if needed.
The Thunderbolt 3 version of 2big will be out in the next couple months. No price points have been set. For more information, head to LaCie 2big page.
