ThunderboltEX II Storage Performance

As far as modern day Thunderbolt storage solutions go, I have yet to find something as stunningly fast as the LaCie Little Big Disk Thunderbolt 2. This small device is capable of 1400 MB/s read and 1200 MB/s write, making it my de facto go to drive for testing Thunderbolt.

Inside every Thunderbolt device, you will find a small PCB similar to what you see above. As I stated previously, Thunderbolt is basically external PCI Express, so what we have here is a central controller switching that data from Thunderbolt to a PCIe slot.

To get an idea of what kind of performance we can expect, I ran the LaCie through CDM. As you can see, we reached some pretty impressive speeds here touching 1200 MB/s read and 970 MB/s write.

ATTO was the next benchmark on our list, so we fired it up and gave the LaCie a go. We were able to reach 1284 MB/s read and 901 MB/s write at QD4.

Next up, we loaded up the latest build of Anvil's storage utilities. Here we did quite well with the LaCie reaching a final score of 4389.

 

In our next batch of tests, we used IOMeter and tested the response time of the LaCie LBD Thunderbolt 2 with Queue Depth.

Above, we have the random read response time. Here the LBD peaked at 0.6ms at QD32.

Random write response time peaked at 1.1ms, again at QD32.

With sequential response time, we found a slight increase to 2ms at QD32.

Sequential write response was by far the highest at 6ms.
