The Bottom Line

Akitio rounds out the Thunder3 lineup with a budget friendly high performance multi-gigabit NIC that's ready to travel.

Adding to our catalog of Akitio products reviewed, we move on from the impressive Thunder3 Quad X in March to the Thunder3 10G NIC today.

The Thunder3 10G NIC is aimed at consumers that have an available Thunderbolt 3 port and want the quickest network connection possible. Designed to be compact and portable the Thunder3 10G is bus powered offering a recessed Thunderbolt 3 connection along with enclosure protection with a silicon cover.

Along with its prowess as a 10Gbe NIC, the Thunder3 does support multi-gigabit networks such as 1, 2.5 and 5Gbe and is even backwards compatible all the way down to 100M Fast Ethernet including Jumbo Frame 9K support. As mentioned above, compatibility includes Windows and Apple machines with an available Thunderbolt 3 port.

MSRP of the Akitio Thunder3 10G NIC comes in at $279.99 with a two-year warranty.

Pulling it apart, I removed the four end screws and slid out the heat sink that includes the PCB.

For testing, I paired the Thunder3 10G with my ASUS C10C 10Gbe adapter using Cat6 cable. To throw data back and forth I used netperf and starting out with 1Gbe, the Akitio Thunder3 brought in 941Mbps. Moving to 2.5Gbe we see 2088Mbps and 5Gbe reaches 4159Mbps. Testing out 10Gbe, performance tops out at 8729Mbps.

The Thunder3 lineup from Akitio spans a broad portfolio of storage, networking and eGPU solutions. As of today, we have tested all three of those solutions and the build quality top to bottom is superb. I enjoyed the unique design of the 10G adapter with large air gaps and the heat sink stack to keep the unit cooled passively but even more, I'm pleased to see Akitio think outside the box and include the silicon sleeve knowing this solution is going to be thrown into a bag daily as you travel.

The performance was quite good with the Thunder3 10G but throughput did fall off as we increased available bandwidth. This is most likely due to the workload as it wasn't heavy enough as the pipe opened up. That said, with 1Gbe we did see 941Mbps and that moves to 2088Mbps with 2.5Gbe. At 5Gbe, results came in at 4159Mbps eventually peaking at 8729Mbps with 10Gbe.

Overall, I did enjoy the Thunder3 10G as it's such a compact bus-powered solution that opens you up to a world of high-performance networking. With that said it does represent a cheaper alternative for consumers wanting to add wired networking to their Thunderbolt 3 enabled MacBook or Notebook as the $279.99 MSRP is nearly $300 dollars cheaper than the next competing solution.
