If you've been looking for a powerful and versatile Thunderbolt 3 docking station that restores many of the ports and connectivity that have been removed on modern day laptops, take a look at the 20TB 2big Dock 2-Bay RAID Array Thunderbolt 3 from LaCie. The 2big Thunderbolt 3 Dock delivers a storage capacity of 20TB, which is comprised of two 10TB Seagate IronWolf Pro 7200 rpm SATA III 3.5" enterprise-class hard drives.

Also supported is RAID 1 and JBOD.

The back of the 2big is equipped with two 40 Gb/s Thunderbolt 3 ports and one 5 Gb/s USB 3.0 Type-C port, all of which allow you to interface with your host system at speeds up to 550 MB/s. The Thunderbolt 3 interface can also be used to connect two 4K displays or one 5K display, as well as daisy-chain up to five additional Thunderbolt 3 peripherals together. If you need to power your laptop, the USB Type-C port provides 27W of power, while the Thunderbolt 3 interface provides 15W of power for charging USB Type-C laptops. Additionally, there is a DisplayPort interface that supports 720p, 1080p, 4K, and 5K displays.

On its front, the 2big has a built-in USB 3.0 Type-A port, which can charge your USB device or connect a USB drive or digital camera for offloading files, as well as a CompactFlash Type I and UHS-II SDXC card slots, allowing you to directly download content from your drone, DSLR, GoPro, and more. This dock can store hundreds of hours of 4K footage and hundreds of thousands of raw images.

The LaCie 20TB 2big Thunderbolt 3 Dock includes a Thunderbolt 3 / USB Type-C cable and an external 60W power supply. If you want to use this dock with your USB 3.0 Type-A system, a USB 3.0 Type-C to Type-A cable is available separately. Protection is provided by a limited 5-year warranty.

Thunderbolt and Thunderbolt 2 are only supported when Apple's Thunderbolt 3 (USB Type-C) to Thunderbolt 2 Adapter is used with systems running macOS 10.12 Sierra or later.

LaCie External HDD Reviews

Reliable, easy to set up and manage

By Rain
Rated 5 out of 5
Date: 2022-07-17

This is my second LaCie 2big RAID array. I bought it because I needed more capacity. The five-year-old one still runs like a champ. I've had zero issues with the devices or the simple management software. Setting them up as RAID 1 (to store two copies of the data) takes a couple of seconds, and then you're good to go. Using a Thunderbolt 3 cable makes for fast transfers to and from my main machine or the other RAID device. It looks good, too!

Fast reliable storage

Works well with the Thunderbolt M.1 Mac I paired it with. Very fast, like having a 36TB internal hard drive. If I run out of space, I'll add another.

Great Product

I have used these drives for several years in my home office lab. Very reliable and good support. You do need to make sure that your cabling is compliant if you do not use the cables provided with the drive. That being said very reliable product.

It's fast, but it never seems to turn off

I'm using this as a Time Machine Backup for a 8TB hard drive in my Mac. I was using an older hard drive that couldn't even do a partial backup of my computer in almost 2 months. So, it was finally time to upgrade. This one did a full initial backup in like 6 hours, so it's definitely fast. I agree with the other reviewers that it is kind of loud, although my old hard drive was a LOT louder. The only downside is, it never seems to turn off. The blue light isn't on, but the fan still seems to run. So, I've just found myself unplugging it instead. Kind of a pain, but at least it actually backs up my computer!

Nice and compact, minimalist management software not great

This unit has a nice and compact footprint. The capacity in raid 1 mode meets my needs. Very quiet in operation. However keep in mind the minimalist management software approach by Lacie. They only offer a Raid Manager and not a desktop manager like they offered with their older products. The lack of control for the extremely bright blue status led on the front panel means that that led is very glaring especially in reduced lighting situations.

Third LaCie array and not disappointed.

This is now the 3rd device I have, the first two are connected with Thunderbolt 2 and this direct via TB3. Have it sitting on my desk and is fairly quiet, but I do hear the hum of the device. The other devices are connected with a long (25ft) optical cable so the drives can sit in a cabinet behind my desk, out of the way and quiet. Was looking to get another TB-3 cable, so I could do the same with this device. Pricey!! For now, it will be sitting on my desk. Always partition to RAID-1 for redundancy on the LaCie arrays and is working as designed. My only fault with the drive (and my unique issue), since I now have 3 versions of the arrays, I now have 3 different desk-top managers or RAID monitor running. Really a pain and I wish that LaCie as a company would make some better software to view/manage these drives. Only reason I am giving it 4*

Good hardware, bad software

Terrible experience using the software trying to convert it Raid 1. Otherwise working fine.

Works as it's supposed to. Setup took a little longer than I would have liked (had to restart system multiple times), but nothing too complicated and now everything is quite simple and easy.

If I fill up the hard drives can I buy the exact same replacement drives and swap them out? Is this a bad practice if I still want to access the content that's on the removed drive in the future?
Asked by: Dan
Yes, the drives on the LaCie 20TB 2big Dock 2-Bay RAID Array Thunderbolt 3 BH #LASTGB200004 can be swapped for Seagate drives if you run out of space. It is not bad practice so as long as you also have that data backed up elsewhere.

Is there a way to turn off the blue light, any options under LaCie's Manager software?
Asked by: Philip
Hello, There are no options in the LaCie RAID Manager that allow to turn off the Blue LED. This is a status indicator as well as a power indicator to give important warnings about the state of the 2big. The list of colors below helps you identify the general status of your LaCie 2big Dock. Color State Solid blue Ready Blinking blue Activity Slow blinking blue (10 second interval) Power-saving Fast blinking blue Startup and shutdown Blinking red and blue RAID initialization or synchronization Blinking red (1 second interval) Temperature warning, drive failure or fan failure Solid red Temperature critical or fan absent Regards

Can a LaCie 20TB 2big Dock 2-Bay Raid Array Thunderbolt 3 be purchased pre-formatted ("out of the Box") for Windows 10 PC and RAID 1? Possibly B&H could do this formatting?
Asked by: Tom
While you can not purchase the 2big Dock in this configuration, it is very easy to change. You will use the LaCie RAID manager ( LRM ) to change the RAID to RAID 1 then the LRM will auto format for Windows 10 PC. The LaCie RAID Manager can be downloaded at this link. https://www.lacie.com/support/software/lacie-raid-manager/
