Thunderbolt Software
Consumers dealing with Thunderbolt 3 must understand that this is cutting-edge technology. It is imperative that the drivers and the Alpine Ridge firmware be up to date in order to ensure a smooth usage experience. GIGABYTE has a driver update as well as a firmware update tool available for the GA-Z170X-UD5 TH motherboard, and other system vendors should also have similar updates available.
The Thunderbolt software component gets installed along with the driver. Unlike traditional USB, every connected Thunderbolt peripheral must first be authorized to connect before becoming accessible. This authorization can be permanent or on a case-by-case basis. Management of authorized devices is done through the Thunderbolt software.
The software also allows users to check the driver and firmware versions.
Power Consumption
Power consumption of the Thunder3 Duo Pro units were recorded under various conditions. While using the device in a standalone mode (i.e, just connected to the host, and no daisy chaining involved), the unit idled at around 5.4W and had a peak power consumption of around 12.1W. This was with two of the Intel SSDs in RAID-0 in the course of our benchmarking routine.
Benchmarks were also processed with the typical usage scenario of high-capacity hard drives. Two 8TB Seagate Enterprise NAS HDDs (7200 RPM) were configured in RAID-0 for this purpose. Peak power consumption was around 40W, but the unit stayed between 24W and 28W throughout the course of our benchmarking.
Adding the SanDisk Extreme 900 to either of the above configurations drove up the power consumption at the wall by around 5 - 8W.
Concluding Remarks
The Thunderbolt ecosystem has received a major boost with the release of products and peripherals supporting Thunderbolt 3 with its Type-C connector. Intel has managed to create a compelling case for the inclusion of Thunderbolt 3 in various systems due to the unique features of the Alpine Ridge controller. The integration of a USB 3.1 Gen 2 host controller has emerged as a key aspect.
Coming to the business end of the review, the 2-bay Akitio Thunder3 Duo Pro performed flawlessly in our testing, and gave expected results in various benchmarks. More importantly, thanks to the presence of a two-port controller, it could easily bring out the various advantage provided by Thunderbolt (daisy chaining etc.). The availability of a USB 3.1 Gen 1 device port ensures that the unit can also be used with systems that don't have Thunderbolt 3.
The unit has a solid feel and a pleasing industrial design. The tool-less installation procedure for the drives is welcome. The unit includes an active Thunderbolt 3 cable (capable of handling 40 Gbps), and, for a cutting-edge product, the street price of $378 sounds reasonable. That said, there is scope for improvement in the product - it would be nice to have easy hot-swap capabilities similar to, say, the LaCie 2big Thunderbolt 2. A notch / plastic key to help in setting the RAID level would also be welcome. The drive bay / slot could also be designed to make drive removal / replacement simpler.
Going through the specifications of the Thunderbolt 3 peripherals currently announced / available in the market (including the Akitio Thunder3 Duo Pro) shows that Windows support is being worked upon first, and not Mac OS X. This leads me to believe that Thunderbolt has well and truly arrived for the mass market. Widespread usage is bound to bring down the premium associated with Thunderbolt right now. One can definitely say that Thunderbolt will not go the Firewire way.

Agreed. If performance is what you seek, this maybe it;https://www.cinema5d.com/faster-than-fast-sonnet-f...

I am more of a Mac guy then a Windows or a linux guy.I own 3 macs
I own 3 windows pcs
I own a linux pc
Thunderbolt is all over my home and I use it for a lot of IT work on Macs.
A portable 2 drive piece of gear like this allows for rescue work.
Simply have a ssd in one slot with a mac os and a blank ssd 2tb samsung. go to a clients place
boot with it and then clone and rescue the dead mac's hhd on the big ssd in your other slot.
I do this now with an older version of thunderbolt then this one. Works great.
I have owned a dozen thunderbolt devices and they are day and nigh over most usb3 devices in terms of being a reliable stable external booter. None of this matters to most none mac users.
One of the great features is I can plug in a thunderbolt mac os and boot most macs.
Windows never really allowed this. So to complain about a system like thunderbolt costing too much is okay but the truth is when you realize what thunderbolt 1 and thunderbolt 2 can do to and with someone else's mac you would say that it is too cheap .

Is it just me or did you really comparr a performance of USB 3.1 Gen.2 SSD connected directly to PC's GEN2 port, vs it connecting to GEN1 port of a DAS and claimed that performance drop is purely due to DAISY CHAINING?ganeshts - Sunday, April 17, 2016 - link
Nope.The USB 3.1 Gen 2 SSD is first connected to a PC's Gen 2 port.
In the second case, it is connected to the Thunderbolt 3 port of the second DAS unit. Note that Thunderbolt 3 can support both Thunderbolt peripherals as well as USB 3.1 Gen 2 devices for daisy chaining. Only obvious restriction is that USB 3.1 Gen 2 devices can appear only at the end of the daisy chain.
Also, please read specifications carefully for the USB 3.1 Gen 1 port of the DAS - The Gen 1 port is a device port - i.e, it can connect to a PC directly. It can't connect to another device like the Extreme 900 Portable SSD.

1.) Could you please add USB 3.1 results for direct-attached? (just use USB cable instead of thunderbolt). Presumably the same, right? So, what is the point of Thunderbolt here? Daisy chaining?2.) Temperature is steadily increasing in your test. 10 minutes is quite short-ish test. What is the steady-state temperature and does it throttle at that temperature?

(1) The USB 3.1 port is USB 3.1 Gen 1 - Maximum possible bandwidth on that is theoretically 5 Gbps, but, in practice, for RAID-0 SSDs, one would get around 450 - 500 MBps. So, it will not be the same as that of Thunderbolt 3 - where we could get around 800 MBps(2) Temperature for SSD configuration was with the fans completely turned off. You can see that the fan 'on' case for HDDs shows that even after more than 250GB of continuous data transfer, the temperature of the HDDs is within 5C of the temperature prior to the start of the transfers. I don't expect throttling to be a concern. If it is (depending on the SSD or HDD in use), one should just turn on the fan.

Pretty underwhelming for the enormous price; USB3 is fast enough to handle three or even four drives if there's hardware RAID on the other end, so Thunderbolt only really offers an improvement if you're handling a JBOD enclosure, and even then two drives won't really justify it.Also, for the price, why aren't these hot-swap bays? Someone wanting to use paired drives in a mirror setup would benefit from being able to hot-swap in a replacement, and for the money you're spending I'd think that pretty reasonable.
Lastly, couldn't this be bus-powered? Even 3.5" drives shouldn't require so much power the bus can't handle it, plus any good RAID controller should be able to spin them up separately (so you're not drawing peak power for both drives simultaneously).
I dunno, I get that Thunderbolt is still a premium product, but it still feels as though the actual quality of design and features you're getting is severely lacking. Besides, being the first Thunderbolt 3 enclosure for two SATA III drives is meaningless as even Thunderbolt 1 is more than fast enough for that. Even the bigger "high end" enclosures are surprisingly poorly made and thought out for the amount of money you need to drop on them; a networked iSCSI device using ZFS with l2ARC will meet most needs, and the NAS/SAS options are just way better.

As a thunderbolt user, there are several other benefits (especially for Mac's) that is brings to the table. For example, I added an external HDD, then added 5 more, 1 by 1 as time went on and as needed, for a total of 6, but only using the 1 port. On Mac's, ports are a valuable commodity. On this same iMac, I only had a few USB ports and they were quickly used up for various things. So that left the thunderbolt port... but i was able to connect 5 devices on it. None of them came even remotely close to using it's bandwidth, but for me, it wasn't about that, or about speed... but expandability. That is something worth noting, for sure. Granted, in PC land, this isn't really a concern, but on Mac's, it's a huge thing. There's also an aesthetic factor to daisey chaining, over a spiderweb hub solution.Haravikk - Wednesday, April 20, 2016 - link
True, but my main point was that you're paying a pretty big premium for the Thunderbolt aspect of this device, for what is overall a pretty poor product; two 3.5" bays, not really setup well for 2.5" drives, not hot-swappable, not actually all that compact. Even little things haven't been thought through, like the place of the Thunderbolt ports under the fan, limiting you to a smaller fan size (bigger is always better when it comes to noise after all).Also, technically it's possible to create daisy-chained USB devices too (each one would integrate a three port hub, with one port for whatever it actually does), the only difference with Thunderbolt really is that it's a crucial part of the design so manufacturers are forced to enable chaining, whereas USB device manufacturers are happier cutting their costs and forcing us to rely on hubs.
Also, if I've understood you right and you've got six HDDs, I'd seriously consider an 8-bay NAS instead. If you're fine with command line stuff then you can set that up with ZFS backed iSCSI, format the iSCSI volume as ZFS on your mac and assign it a chunk of your internal drive as a cache, and it's just better overall (if a little complex to setup in the first place). If someone manufactured a Thunderbolt cache device that I could plug straight between a Mac and a NAS then that would be the perfect option, but until then it's big local cache plus NAS with tons of drives for me =)
