    LaCie today announced its next-generation 2big professional 2-bay RAID storage solution, debuting the LaCie 2big Dock with Thunderbolt 3 connectivity for use alongside the new 2016 MacBook Pro, which supports Thunderbolt 3.

    The LaCie 2big Dock is a docking station designed for media professionals, offering a wide range of ports for a streamlined creative workflow. There are front-facing SD and Compact Flash Card slots to pull images off of memory cards from cameras and drones, plus it can connect to 1080p and 4K displays.


    There are dual Thunderbolt 3 ports for driving a compatible laptop while daisy-chaining up to five additional Thunderbolt or one USB-C drive, and included USB-C ports can charge an iPhone or other similar device. An adapter cable is included for use with USB-A devices.

    LaCie's latest dock offers up to 20TB of storage, a 25 percent increase over the previous version, enabling it to store up to 650 hours of 4K 30fps footage or up to 200,000 RAW images. It supports transfer speeds of up to 440MB/s, for transferring the equivalent of an hour of 4K footage in a minute.


    The dock features a stylish aluminum enclosure and a thermoregulated fan to keep it cool, and it supports Seagate IronWolf Pro enterprise-class devices and RAID optimization.

    The LaCie 2big Dock will be available in 12TB, 16TB, and 20TB capacities through LaCie resellers starting this summer.

    i would love a feature to automatically download every photo/data off an external card as soon as you plug it in.
    just save everything to /CardName/DateAndTime, then blink to inform that transfer is over. boom.

    Is there an SSD cache or some other mechanism that will allow it to reach anywhere near that 440MB/s mark? Or is this just marketing hooplah for theoretical USB 3.1 throughput?

    2 disk raid? No parity? Isnt that very insecure?

    I wonder what the price is. Silly, I know, but I like the build in card readers. I will be interested when they release it.

    I thought TB3 was 40Gbps... 440mbps is not even close

    The speed is 440 MBps (big 'B' for bytes), which is approx 3.5 Gbps. That's the max speed of the two hard drives, not at all bottlenecked by the interface. Seagate rates their 10TB drives at 220 MBps each, with two striped you'll get 440 MBps.

    I have 2 x Seagate Ironwolf 8TB (not the Pro Version) in a Terra-Master D2-310 RAID 0, connected to a 2016 MBP via USB-C (3.1, 2nd Gen).

    I get 440-460 MB/s

    Not a Lacie fan, had two of their drives in my time and both failed. I prefer to go the route of NAS, far more reliable, accessible outside the network and for most people is more than fast enough 150 MB/s over wifi. I totally get video editors who want faster speeds but for most people they're just backing up pictures and archiving on such a disk and they're vastly over spec'd. Personally I would use an SSD USB 3 drive, edit the video project and then archive to cheaper spinning media on a network device so it can be accessed anywhere anytime if needed later on.

    Driving this in raid 0 mode is insanity! Imagine 20 tb of data lost because of a raid error!!! So you'll end up with 220 Mbps. What do you need tb3 for here?

    I just want a small size TB3 drive, like 1tb.....looking like it might be years before anybody makes a small one though.....

    For daisy chaining and avoiding adaptors with new USB-C-plug-only Macs. In principle also the ability to forego an extra power supply (not sure if possible with this device).

    Lacie lists that "No matter what Thunderbolt interface your computer runs on, the LaCie 2big Dock will connect to it via the Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter." Does that really mean you could hook a Thunderbolt 2 computer up to this unit? Because if that is the case that is pretty darn cool.

    Exactly. This product is used as a single-cable dock, TB3 will give enough headroom in bandwidth for the RAID drive, the card readers, and other components down the daisy-chain. The choice of stripped RAID0 fast drive for quick deposit of media, can leave another slower array of drives down the chain for more secure storage / backup.

    To be honest this should have been the dock that Apple shipped alongside with the MBP2016.

    Wow, this looks great and useful with the extra ports. The USB port could also be used to add an XQD reader.

    Knowing Lacie this won't be cheap. I guess the 2big TB3 will start around $799 and top out at $1200.

    The drives mentioned each have approx 220MB/sec sustained thruput performance. 2 drives striped in RAID-0 could deliver 440MB/sec.

    Thunderbolt3 or USB 3.1 gen2 could easily support that thruput if the drives live up to expectation.

    If drives were hybrid SSD/HDD, the thruput could be higher, but only for transfer as large as the SSD cache.

    If HDDs were replaced by SSDs, thruput could be 800MB/sec if striped as RAID-0 array. LaCie does not offer empty chassis without drives, though.

    RAID-0, no parity, built for speed not data reliability. advertised capacity.
    RAID-1, redundancy, reliable if one drive fails. 1/2 the capacity

    A USB3.1gen2 portable drive is all you would need.

    Thunderbolt3 ports have both Thunderbolt and USB capability, and 15watts available. For a single drive, HDD or SSD, USB 3.1 gen2 has all the headroom one might need for performance.

    LaCie has their Rugged Portable and Porsche Mobile drives; there are other portable drives with USB 3.1gen2. Google Search, Amazon, and Apple website all reveal possibilities, and the Mac centric sites have reviews.

    It supports RAID 1 as well.
    --- Post Merged, Apr 19, 2017 ---
    Well, the new MacBook Pros only have TB3. Sure, you could buy an adapter but simplicity sake...
    --- Post Merged, Apr 19, 2017 ---
    Yes, you'll be able to use TB3 devices on TB2 computers if you have the adapter. You're still limited to TB2 speeds though so you're likely better off buying the older TB2 2big for a discount.

    How feasible is it to replace the stock HDD that come with this and drop in Samsung 850 pro SSD drives? Is it as simple as just hot/swap?

    Welcome to the world of and AppleScript. Except for the blink that's the way it works with my Mac mini. I get a message on the Apple Watch instead. :cool:

    cmdlet/code please? ;)

    PS: Does anyone know what recent camera still uses CompactFlash storage? It's almost as old as those original iOMega drives.

    CF is used in the Canon 5D Mark IV, which is canon's latest full frame pro camera, so yes, it does still exist. I believe the latest gen of CF cards are still much faster than most SD cards as well.

    LOL are you serious? That thing has a starting price of $1,200 and doesn't include any drives. It's $1,700 with their cheapest drive options.

    The 2big TB3 is typically priced around $300-$800 INCLUDING drives.

    2big and the product you mentioned are in two completely different market segments.

    The LaCie 6big is a better comparison to your product feature/price wise.

    Understand! :) I did not state clear enough!
    What I mean was, why use TB3 on a 2x HDD which can be used in USB3.0 or eSATA.

    As far as TB3 RAID, i think DATOptic T8C-S6.TB3

    is far better than LaCie6Big

    because the new MacBook Pro doesn't have USB 3.0 or eSATA.

    It does have USB Type-C 3.1 though but using USB breaks the ability to daisy chain further devices on that port.
