The force itself is a Seagate BarraCuda Pro, which is designed for 24/7 operation and features a lengthy five-year guaranty. LaCie additionally contains enhance for one example of forensic lab-based information restoration, will have to one thing unhealthy occur. This is relatively the freebie; this sort of carrier is most often relatively dear by itself.

The force enclosure is designed to stay it working great and funky. Its unibody development (in Apple Mac-speak) is composed of a unmarried, monolithic piece of aluminum and a big, HAL-9000-esque LED. Inside the enclosure is a small fan. Even a tiny airflow can assist to stop meltdowns in maximum desktop-class exhausting drives.

Aside from the enterprise-grade inside of, the true promoting level of the d2 is the array of connectivity choices it supplies. In addition to the 2 Thunderbolt 3 ports, there’s additionally a USB 3.1 Type-C port…

You can clearly attach the d2 to a PC with a Thunderbolt 3 port, however maximum PCs (and Macs) don’t have those ports. That’s why LaCie contains two cables: a Thunderbolt 3 (with a USB Type-C connection at both finish) cable, and a Thunderbolt-to-USB Type-A cable for customers who do not thoughts working at USB speeds—Thunderbolt 3’s pace merit comes into play when daisy-chaining relatively than the usage of a unmarried force (see our efficiency segment under).

Also, if you must attach the d2 to an older Mac and don’t need to use USB for some reason why, you’ll attach Thunderbolt 3 to a Thunderbolt 2 dongle.

Easily probably the most attention-grabbing side of the d2’s connectivity is that it permits daisy-chaining two 4K presentations, one 5K show, or as many as six d2 drives (although you’ll, naturally, attach Thunderbolt 3 drives from different distributors to the chain). It’s additionally imaginable to energy a suitable computer in the course of the latter’s USB-C port, although that is extra of a theoretical characteristic (the d2 can handiest output 15 watts).

Like different LaCie drives, the setup wizard permits you to partition the d2 into each PC and Mac document codecs for document sharing. You can drag a slider to create walls, leaving you with one partition that may proportion information between PC and Mac, and one partition this is only for Macs.

Performance Testing

To take a look at the d2, we plugged it right into a PC with a USB 3.1 Gen 2 connector, in addition to a Thunderbolt 3 connector on a brand new Razer computer, as we had been curious if there’d be any efficiency distinction. Both Thunderbolt 3 (in addition to 2, if truth be told) and USB 3.1 Gen 2 supply greater than sufficient bandwidth for a spinning exhausting force. With the d2 the proscribing issue is not the particular connection in play, however relatively the force output. As you’ll see within the effects, each connections fared about the similar. So don’t be swayed by means of the truth that the Thunderbolt 3 interface is, on the core, “faster” than USB 3.1; for a spinning force, the additional theoretical bandwidth is moot.


We began out with this ageing however well-liked benchmark for garage aficionados who, like PCMark enthusiasts, need the whole thing boiled all the way down to a unmarried rating…

LaCie d2 Thunderbolt 3 (Anvil)

The d2 carried out relatively smartly in Anvil’s rigidity take a look at, making it the quickest unmarried exterior exhausting force we’ve examined to this point by means of a small margin. That’s most likely because of its 7,200rpm relatively than 5,400rpm exhausting force. The small pace spice up may well be useful to inventive pros, for whom time is cash. It’s additionally attention-grabbing that the USB 3.1 take a look at rating used to be a little bit upper than the Thunderbolt 3 rating, however that is throughout the margin of error.

We run this well-liked sequential learn/write take a look at as a result of, for this sort of secondary garage, sequential operations are probably the most related. It’s now not randomly having access to information right here and there, however most often simply writing or studying massive information equivalent to motion pictures, track, high-res pictures, and video.

Once once more, the LaCie d2 sped thru this sequential learn and write take a look at, soaring round 237MB consistent with 2nd for reads and 227MB consistent with 2nd for writes. That’s relatively just right for a unmarried force, and similar to with Anvil, those are the quickest rankings we’ve observed for a non-RAID setup. The LaCie force’s 7,200rpm platter takes credit score for that, after all, however the evidence is within the pudding. It’s dearer than its opposite numbers, however its efficiency partially explains its value. (The different phase is the top class that the Thunderbolt 3 interface and cabling puts on issues.)


At $529.99 for 8TB, the d2 isn’t just dear however wildly dear for an exterior exhausting force of that dimension. The explicit naked force mechanism inside of bought for $299 from e-tailers on its own at this writing. The leisure is going towards the LaCie’s aluminum development and Thunderbolt 3 structure. By distinction, shoppers can get a USB 8TB Seagate exterior force for simply $179, which in reality illustrates the LaCie force’s lofty positioning.

Of route, this is a top quality, full-featured product for the dollars. It runs quietly, has slick device for each PCs and Macs, and can be utilized with a variety of computer systems, each new and previous. The Thunderbolt 3 connectors are in reality the principle promoting level, although, so if in case you have a brand new MacE-book Pro or Windows 10 PC that has a type of modern ports, you may well be eyeballing this force. It’s a backup answer par excellence, definitely, however it kind of feels sensible to spend on it provided that you’re into daisy-chaining drives, and feature a Thunderbolt 3-equipped pc or computer systems (or purpose to within the close to long run).

If you simply need an 8TB backup force, there are a long way inexpensive choices, but when Thunderbolt 3 is a must have, the d2 is a chic, versatile garage answer with options and construct high quality that the majority drives lack.

LaCie d2 Thunderbolt 3 (8TB)

Our Verdict: The LaCie d2, made for folks with more recent Macs, is a quick, versatile, however dear exterior exhausting force with twin Thunderbolt 3 ports for daisy-chaining expandability.
