Concluding Remarks

LaCie's 2big Thunderbolt 2 and the Rugged Thunderbolt are both attractive pieces of technology. For users who just want a plug-and-play experience, both units just work. However, the scheme to change the RAID level is just not intuitive. A very similar problem existed with the LaCie 2big NAS that we reviewed a couple of years back when it came to starting from a diskless configuration. That issue has since been resolved in the later generation NAS units via the use of a dedicated boot up key. Hopefully, LaCie is able to do something for the future generation DAS units to resolve the non-intuitive requirements. We would have also liked to see the 6 TB enterprise drives being used in the unit, but given the cost, one really can't complain. The use of a high quality Noctua fan enables the unit to keep a low noise profile even under high loads.

The LaCie Desktop Manager program also needs some updates. Display of RAID rebuild progress would be nice. The ability to change the RAID level of the unit from within the program would also be quite useful. On Windows systems, we found that the program would recognize the units only over USB. In addition, TRIM capability seems to exist only over USB for the Rugged Thunderbolt SSD version. Though the last aspect is something dependent on the system / OS and the ncessity is also dependent on the nature of the Rugged workload, prospective consumers would do well to remember that and keep the Rugged connected over USB to maintain performance levels.

On the whole, LaCie has managed to deliver a compelling solution for multimedia professionals. The devices work as expected, performance seems to be good enough for the target market (given the device parameters) and pricing is in-line with similar units from other vendors. Thunderbolt's capabilities are best brought out in daisy chaining scenarios (as we saw that a single unit was able to get better performance over USB 3.0 in our testbed). So, it is definitely a great idea on LaCie's part to integrate both USB 3.0 and Thunderbolt connectivity options in the 2big Thunderbolt 2 and Rugged Thunderbolt.

    So... thunderbolt is slower, more power hungry and more expensive than USB 3.0. And it's effectively unavailable. I can see why Intel integrates USB 3.0 into their chipsets and not Thunderbolt.

    Of course, I understand that this is a function of volume; Thunderbolt doesn't really sell and is an Intel exclusive whereas USB 3.0 controllers are made by every man and his dog, so it's much more optimized both in cost and data stream efficiency, not to mention driver compatibility. But this still begs the question: why even include Thunderbolt? It's objectively worse than USB 3.0 and just needlessly increases the price of both Apple and peripheral products.

    I would like to see the benchmarks under Mac OS too. They don't rely on bios drivers for thunderbolt and use their own. I think Linux will have the same driver later this year but I think on Mac thunderbolt driver is more optimised.

    Agreed. I'd really like to see a USB 3.0-Thunderbolt shoot-out under OS X and Linux as well!

    I don't know if this is possible Ganesh, but if you could get access to a mac with thunderbolt, it would be pretty neat to see! :)

    Yea I'm a little concerned by these numbers, I mean... Isn't the Mac Pro supposed to be able to drive a 4K display over TB2? I would imagine that's a much more bandwidth heavy application than file transfer. Also maybe the devices themselves or the add-on card are the limitations?
  • Essence_of_War - Wednesday, July 9, 2014 - link

    Yeah, I think it's pretty clear that in no case is the theoretical limit of TB being saturated.

    It's possible that the speed differences are within the margin of error, but my first guess would be some sort of driver/controller issue for TB on Windows.

    I'm a Big Mac Mini fan... I've been trying to rationalize TB, and just can't quite get there. I use external drive over the network for media and backups. I wound up buying a 4-bay USB 3.0 box for $250; with 4-4Tb drives, I have 12Tb of RAID 5 storage for under $1000. So I really don't get the price tag on a 2-bay TB drive.

    I get 230 MB/s on Blackmagic. That's not that much slower than my buddy's Promise 2 RAID, the reason being the spinning drive are the main limiting factor. And, 30+ % cheaper. And 230 is fast enough for anything I need . You really need 6 bays or SSDs to take advantage of TB.

    If I had to do it over, I'd consider the OWC thunderbay box. $450 vs. $250 for the Dyconn Quartz4 box I bought. Just depends what you're using if for. I'm almost there!

    I may be off on the TB speeds. ..just looked at a review on owc , it's twice the speed of USB 3 on RAID 5 ... Like I said, I might decide different today
  • ganeshts - Wednesday, July 9, 2014 - link

    As I mentioned in the concluding remarks, for these particular devices, TB is useful only in the daisy chaining scenario. Otherwise, USB 3.0 is going to deliver better performance.

    Apologies for not testing with Macs. I should have probably noted in the very beginning that we are going to start monitoring Thunderbolt performance on Windows from my side. For Mac-based coverage, Anand is the best bet (for example, the LaCie Little Big Disk review that he put out earlier this year -- which I have also linked in the article).
  • M/2 - Thursday, July 10, 2014 - link

    Agreed! USB 3.0 beats any 1 or 2 drive configuration (IMO), simply because because the drives can 't fill the TB bandwidth (unless you're using SSDs). Sure, TB is cool, but adding USB3 would make a more versatile package.

    FYI, I see the OWC thunderbay price is now $500, up $50, people must be buying them. Still too much of a premium IMO (unless you're using SSDs and/or really need 500+ Mb/s)

    You really need to include the Mac numbers; otherwise, nobody will be holding PC manufacturers to task in making these devices perform remotely near their potential. The current situation is abysmal, and with zero reason other than near total incompetence.
