I have a Sonnet Echo Express III-D Thunderbolt to PCIe Card expansion chassis connected to Bus 2 on my new Mac Pro. There are no other devices on this bus. I purchased it with the Thunderbolt 1 card and received the Thunderbolt 2 card today. I used Black Magic to test the speed of my Samsung EVO 840 1TB SSD installed in the expansion chassis using the Sonnet Tempo SSD Pro. I have attached screen shots of TB1 and TB2 tests. As you can see no difference in performance.
Got a tip for us?

Sonnet TB2 card upgrade results

so i am a little confused, shouldn't the TB2 be 'twice' as fast? [theoretically]..am i missing something?
If I'm understanding the poster correctly, he's testing the speed of one installed Samsung SSD.
The top speed of that SSD is less than the maximum throughput of Thunderbolt 1. Thunderbolt 2 won't change anything. I'm pretty sure he could install up to two of those SSDs without hitting the speed limit of Thunderbolt 1.
my card arrives on tuesday. i'll test with my 2-drive (840 EVO 1TB) RAID0.
wouldn't expect there to be any difference with one drive. their tempo pro and tempo cards experience no difference -- 1 SSD is nowhere near the max of those cards nor of the TB1 bandwidth limit.
a 2-drive SSD exceeds the limits of the tempo SSD card (i have both tempo and tempo pro) and comes nearer to the limits of TB1. TB2 could provide a bit more headroom.
we shall see in a few hours.

posted my findings with a 2x840 EVO RAID0 in my thread about real-world TB enclosure performance.
in summary: reads got bumped 40-200MB/s; writes saw a very modest improvement. All that changed was the TB2 card.

Imagine you are driving at the top speed on a straight, empty highway with 3 lanes. Now imagine the highway has 6 lanes empty. Will the car go faster?
i agree..follows my rule when i don't get something right away, talk to me like i'm 5.
