We have already talked about the Thunderbolt software and how it provides more security compared to connecting traditional USB peripherals. Detailed coverage of the Intel SSD Toolbox is also beyond the scope of this review. However, there are a couple of aspects - performance consistency and power consumption - that bear relevance in the day-to-day usage of the Thunder3 PCIe SSD.

Performance Consistency

Our performance consistency test takes the robocopy benchmark described in the previous section and instruments it to record the drive temperature as well as instantaneous transfer rates during the process.

The active thermal solution helps a lot, with the SSD barely going above 33C in the course of transferring more than 250GB of data continuously. There is absolutely no thermal throttling at play in the Thunder3 PCIe SSD, and we don't expect any workload to be really able to stress the fan-based cooling mechanism much.

Power Consumption

The power consumption of the Thunder3 PCIe SSD was recorded at the wall while processing the CrystalDiskMark benchmark, as well as over the course of processing our DAS test suite (including PCMark 8 storage bench).

The above graphs show that the PCIe SSD itself can consume upwards of 16W for certain workloads. The unit idles at around 7W. Utilizing the DisplayPort output and/or adding another device in a daisy-chain configuration is also bound to drive up these numbers (particularly if the added device is bus-powered).

Final Words

The strength of the Intel SSD 750 lies in performance consistency with random I/O intensive workloads. This is not something evident in the typical DAS workload. That said, the SSD 750 has the highest possible capacity of any consumer drive model that uses a PCIe 3.0 x4 NVMe interface. Considering the target market, it makes sense that AKiTiO uses the highest capacity model in the only version of the Thunder3 PCIe SSD. On the other hand, a bus-powered enclosure using a M.2 SSD with a better guaranteed endurance rating (in terms of drive writes per day (DWPD)) would be nice, though such a product would probably target a different use-case.

Coming to the business end of the review, it can definitely be said that the Thunder3 PCIe SSD is a unique product - It is the only product we are aware of that can put the Intel SSD 750 to use in a direct-attach scenario. The key here is that the storage is not tied to a single computer, and a portability option is available. Such fast and massive storage is a boon for multimedia editors working as a team, or, across multiple locations.

The pricing aspect is a bit shocking at first - $1300 for 1.2TB is more than $1/GB (the last Thunderbolt SSD that we evaluated - the LaCie Rugged Thunderbolt - was priced at $1/GB, but limited to SATA speeds). However, one must note that the Intel SSD 750 1.2TB add-in card itself still retails between $1018 and $1150. The Thunderbolt 3 enclosure with daisy-chaining capabilities and a dedicated DisplayPort output adds comparatively little to the final cost of the Thunder3 PCIe SSD. Considered standalone, the Thunder3 PCIe SSD is an technically exciting product that will also draw the attention of professional users. We would like to see AKiTiO add a bus-powered PCIe SSD to round out their Thunderbolt 3 Series.

    Where are the PCIe adapters for thunderbolt 3?
  • osxandwindows - Thursday, June 2, 2016 - link

    When I first saw the title I thought, hell yea.
    A PCIE thunderbolt 3 enclosure.
  • AppleJon - Thursday, June 2, 2016 - link

    Would taking the drive out and putting a graphics card in the pcie slot be something possible?
  • CharonPDX - Thursday, June 2, 2016 - link

    No, for quite a few reasons:
    1. The enclosure isn't very large, so a long video card wouldn't fit.
    2. It doesn't have a power connector for video cards that require more than the PCIe bus provides.
    3. Even the PCIe bus is limited by the 12V, 6A power supply (less than 70W available to the card.)
    4. It only has a x4 PCIe slot, that doesn't appear to be open-ended, so no x16 cards.

    In theory, you could throw a low-power x4 video card in, but those aren't "powerhouses" by any means. They're meant purely for adding more displays. Again, I suppose you COULD do that, but there are dedicated graphics Thunderbolt chassis on their way soon that would be far cheaper than buying this just to use it for a video card.

    So yes but with limitations. 1300$ minus the 1100$ for the SSD is not to bad if you need it. I know the GPU "real' enclosure are comming but still currius to know if anandtech would have the time to try something like that? With the new finfet GPU comming could make things even more interesting on the low power side pcie power only type enclosures.

    I'm surprised that no one is mentioning the fact that the development kit mentioned by Ganesh is available for $280 with free shipping and comes with a x16 PCI-E connector, Thunderbolt cable and everything needed to get started.

    It also has a pretty standard power connector for providing bus power up to 75W. For more powerful video cards, one could easily buy one of those kits, install it in some off the shelf mini-ATX/mini-ITX/fancy custom case with a reasonably large ATX power supply (350W would be plenty for a single card) and have a nice custom made graphics card enclosure.

    I'm sure the mod community would find plenty of fun in packaging this development kit in a dedicated GPU case :-)
  • samer1970 - Friday, June 3, 2016 - link

    why do that ? Thundebolt3 GPU cases already exist , you can buy them from Razer , and powercolor .. and many chinese companies.
  • danbob999 - Thursday, June 2, 2016 - link

    Another thunderbird device. Another overpriced device.
  • damianrobertjones - Thursday, June 2, 2016 - link


    Really? STOP MILKING CONSUMERS you idiotic companies. It's annoying.
  • Peterman1 - Thursday, June 2, 2016 - link

    This price really isn't that bad considering the intel ssd inside is $1100. The company then has to include the aluminum housing, circuitry, and make a little profit on the device.
