Nobody ahould be expecting that a flush actually flushes because the biggest manufacturer of hard drives tells you it doesn't.
Read documents and specifications like this tester didn't do.
And don't use random enclosures and pull the plug since the design spec assumes hold up times and sequencing that enclosure may not be compliant with.
Please stop replying with misinformation all over this thread.
The NVMe spec is available for free; you should read it.
And you're 100% wrong about the enclosure too. It's driven by an Intel TB bridge JHL6240 and the drives are PCIe NVMe m.2 devices. Power specs are identical to on-board m.2 slots with PCIe support (which is all modern ones). There is no USB involved.
See my other reply to you where I explain what Flush actually does (your comments about it are also completely wrong).
I apologize.
Your TB test sounds valid but did you verify with manufacturer that power loss protection or power failure protection works in your TB enclosure? Is that a fair assumption or do you need to ask?
