Hi Les, I have performance variations of 3x between cold boot and hot plug with the Samsung 512GB X5 on Windows 10.
I understood this was because TB3 vendors have trouble with the re-negotiation of the Thunderbolt connection after hot plug.

The computer I used is a brand new HP Zbook Studio G5 with Samsung NVMe SSD boot drive running Windows 10 Pro update 1909.

Samsung 512GB X5 Magician benchmarks:
Benchmark #1: 2803/588/263427/25390 after disconnect/re-connect no G2 hub
Benchmark #2: 2806/1877/263427/251220 after cold boot, no G2 hub
Benchmark #3: 2818/589/261474/251220 after disconnect/re-connect with G2 hub
Benchmark #4: 2753/1386/259277/252192 after cold boot with G2 hub

Samsung Tech support confirmed that their tech support center has heard from customers experiencing the same issue.
I also found a lot of variation using TB3 add-in cards from ASUS (ThunderboltEX3), and Gigabyte (Alpine Ridge, Titan Ridge), which is why I wondered if you have tested or found differences in performance with hot plug, in which case it might be a useful test to add. I am definitely disappointed to need a cold boot to get best performance.

Now that you have switched to the ASRock X570 Creator as your test bed, I would like to know if the ASRock X570 motherboard TB3 implementations (Creator onboard TB3 and Taichi+PCI TB3 card) have reliably solved this issue.
Thanks for any help.

It is a given that the test speed would be different, the result of other background activity in the system, especially after a cold boot. We test during ideal conditions and I would be the first to write about it if the tests weren’t always consistent during these conditions. Yopu are also speaking on the X5 in a Plugable report? Are you finding same with this device?

Are the speeds identical or different in any way?
I get substantial differences between these two scenarios with the Samsung X5.

It seems any additional cost would easily be passed to the consumer, as the new device is TB3 with USB3 fallback.
